■ Safety Precautions CAUTION Do not touch the terminals while power is being supplied. Doing so may occasionally result in minor injury due to electric shock. Do not allow pieces of metal, wire clippings, or fine metallic shav- ings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur. Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. CAUTION - Risk of Fire and Electric Shock a) This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that does not allow fire to escape externally. b) When using more than one shutoff switch, always turn OFF all the shutoff switches to ensure that no power is being supplied before servicing the product. c) Signal inputs are SELV, limited energy. (See note 1.) d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2 circuits. (See note 2.) If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switching conditions. Note 1: An SELV circuit is one separated from the power supply with double insulation or reinforced insulation, that does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC. Note 2: A class 2 power supply is one tested and certified by UL as having the current and voltage of the secondary output restricted to specific levels. V

CAUTION Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose screws may occasionally result in fire. Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents. A malfunction in the Digital Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Digital Controller, take appropriate safety measures, such as installing a monitoring device on a separate line. When inserting the body of the Digital Controller into the case, confirm that the hooks on the top and bottom are securely engaged with the case. If the body of the Digital Controller is not inserted properly, faulty contact in the terminal section or reduced water resistance may occasionally result in fire or malfunction. When connecting the Control Output Unit to the socket, press it in until there is no gap between the Control Output Unit and the socket. Otherwise contact faults in the connector pins may occa- sionally result in fire or malfunction. VI

Precautions for Safe Use Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unexpected events. Do not handle the Controller in ways that exceed product specifications. 1) The product is designed for indoor use only. Do not use the product outdoors or in any of the following locations. • Places directly subject to heat radiated from heating equipment. • Places subject to splashing liquid or oil atmosphere. • Places subject to direct sunlight. • Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas). • Places subject to intense temperature change. • Places subject to icing and condensation. • Places subject to vibration and large shocks. 2) Use and store the Digital Controller within the rated ambient temperature and humidity. Gang-mounting two or more Digital Controllers, or mounting Digital Controllers above each other may cause heat to build up inside the Digital Controllers, which will shorten their service life. In such a case, use forced cooling by fans or other means of air ventilation to cool down the Digital Controllers. 3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product. 4) Be sure to wire properly with correct polarity of terminals. 5) Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires, use stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to cross-sectional areas of 0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two wires of same size and type, or two crimp terminals can be inserted into a single terminal. 6) Do not wire the terminals which are not used. 7) To avoid inductive noise, keep the wiring for the Digital Controller's terminal block away from power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to Digital Controller wiring. Using shielded cables and using separate conduits or ducts is recom- mended. Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component). When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the Digital controller. Allow as much space as possible between the Digital Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge. 8) Use this product within the rated load and power supply. 9) Make sure that the rated voltage is attained within two seconds of turning ON the power using a switch or relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur. 10) Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display. 11) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be within easy reach of the operator, and must be marked as a disconnecting means for this unit. 12) Always turn OFF the power supply before pulling out the interior of the product, and never touch nor apply shock to the terminals or electronic components. When inserting the interior of the product, do not allow the electronic components to touch the case. VII

13) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol. 14) Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be set after power ON. 15) The output may turn OFF when shifting to certain levels. Take this into consideration when performing control. 16) The number of nonvolatile memory write operations is limited. Therefore, use RAM write mode when frequently overwriting data during communications or other operations. 17) Always touch a grounded piece of metal before touching the Digital Controller to discharge static electricity from your body. 18) Do not remove the terminal block. Doing so may result in failure or malfunction. 19) Control outputs that are voltage outputs are not isolated from the internal circuits. When using a grounded thermocouple, do not connect any of the control output terminals to ground. (Doing so may result in an unwanted circuit path, causing error in the measured temperature.) 20) When replacing the body of the Digital Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well. 21) Use suitable tools when taking the Digital Controller apart for disposal. Sharp parts inside the Digital Controller may cause injury. 22) Check the specifications of the Control Output Unit and assemble it correctly. 23) When mounting the Control Output Unit, read and follow all relevant information in the product catalogs and manuals. 24) Do not continue to use the product if the front surface peels or becomes cracked.

SECTION 1 Communications Methods 1.1 Overview of Communications Methods Overview ■ Introduction The program for the communications functions are created on the host (personal computer, PLC, or other type of communications master), and the E5CN/AN/EN-HT’s parameters are monitored or set from the host. Therefore, the description provided here is from the viewpoint of the host. CompoWay/F is OMRON’s standard communications format for general serial communications. This format uses a standard frame format as well as the well-established FINS* commands used for OMRON’s PLCs. Therefore, it can simplify communications between components and the host. *FINS (Factory Interface Network service) The FINS protocol provides message communications between controllers in OMRON FA networks. Modbus is a standard communications control method that conforms to the Modicon Company’s RTU-mode Modbus Protocol (PI-MBUS-300 Revision J). Modbus is a registered trademark of Schneider Electric. It supports functions equivalent to the CompoWay/F Read Variable Area, Write Variable Area, Operation Command, and Echoback Test functions. The E5CN/AN/EN-HT supports the following communications functions. • Reading/writing of parameters • Operation instructions • Selection of setup levels Communications are subject to the following condition: • Parameters can be written only when the Communications Writing parameter is set to ON (enabled). 1-2

Note 2: Communications speed, data bits, stop bits and vertical parity can each be set independently in the communications setting level. Highlighted values indicate default settings. Note 3: The communications data length for Modbus must be 8 bits. ■ Transmission Procedure When the host transmits a command frame, the E5CN/AN/EN-HT transmits a response frame that corresponds to the command frame. A single response frame is returned for each command frame. The following diagram shows the operation of the command and response frames. Command frame Command frame Host E5CN/AN/EN-HT Response frame 1-3

Page 16

SECTION 1 Communications Methods Allow a wait time of at least 2 ms before the next command is sent after the host Overview receives a response from the E5CN/AN/EN-HT. ■ Interface Communications with the host are carried out through a standard RS-485 interface, RS-232C interface, or RS-422 interface (E5AN/E5EN-HT). Use a K3SC Interface Converter for RS-485, RS-232C, and RS-422 interface conversion. ■ Wiring RS-485 • The RS-485 connection can be either one-to-one or one-to-N. Up to 32 units including the host can be connected in a one-to-N system. • The total cable length is 500 m max. • Use a shielded twisted-pair cable with wires of a thickness of AWG24 (0.205 mm2) to AWG14 (2.081 mm2). 1-4

Set CompoWay/F or Modbus. • Communications Unit No. (u-no) This parameter is for setting a unique unit number for each of the Digital Controllers. This unit number is set so that the host can identify the Digital Controller when communications are carried out with the host. The unit number can be set to an integer value between 0 and 99. The default is “1.” When two or more Digital Controllers are used, do not set the same unit number. Doing so will prevent normal operation. • Communications Baud Rate (bps) This parameter is for setting the baud rate for communications with the host. The communications baud rate settings are as follows: 1.2 (1200 bps), 2.4 (2400 bps), 4.8 (4800 bps), 9.6 (9600 bps), 19.2 (19200 bps), 38.4 (38400 bps) or 57.6 (57600 bps) • Communications Data Length (len) This parameter is for setting the number of communications data bits. Set either “7 bits” or “8 bits.” 1-9

Page 22

SECTION 1 Communications Methods • Communications Stop Bits (sbit) This parameter is for setting the number of communications stop bits. Set Overview either “1” or “2.” • Communications Parity (prty) The communications parity can be set. Set the parity to “none,” “even,” or “odd.” • Send Data Wait Time (sdwt) The send data wait time is the time that the Controller waits from when it receives a command from the host computer until it returns a response. The wait time can be made longer if the response is returned too quickly for the host computer to receive it. The wait time can also be made shorter to make the communications response time faster. The send data wait time can be set in 1-ms increments between 0 and 99 ms. The default is 20 ms. ● Setting Communications Writing Set the communications writing parameter to ON to allow the host to write to the E5CN/AN/EN-HT via communications. Parameter Setting 1. Press the O Key for less than one second to move from the operation level to the adjustment level. 2. Select the parameter as shown below by pressing the M Key. 3.

SECTION 2 CompoWay/F Communications Procedures 2.1 Data Format Hexadecimal values are expressed by adding the prefix H’ before the number, e.g., H’02. Numbers shown without the H’ prefix are ASCII characters. The number underneath each item in a frame indicates the number of bytes. ■ Command Frame CompoWay/F Text Node number Sub-address SID Command text BCC STX 0 0 0 ETX 1 2 2 1 1 1 BCC calculation range STX This code (H’02) indicates the beginning of the communications frame (text). Always set this character in the first byte. When STX is received again during reception, reception is carried out again from the point where STX was received. Node number • This number specifies the transmission’s destination. • Specify the E5CN/AN/EN-HT’s communications unit number. • A BCD value between 00 and 99 or an ASCII value of XX can be set. • Specify “XX” for a broadcast transmission. No responses will be returned for broadcast transmissions. • No responses will be returned from node numbers other than the ones in the above range. Sub-address The sub-address is not used in the E5CN/AN/EN-HT. Be sure to set the sub- address to “00.” SID (Service ID) The service ID is not used in the E5CN/AN/EN-HT. Be sure to set the service ID to “00.” Command text This is the command text area. For details, see 2.2 Structure of Command Text. ETX This code (H’03) indicates the end of the text. BCC This is the Block Check Character. The BCC result is found by calculating the exclusive OR of the bytes from the node number up to ETX. 2-2

Page 25

2.1 Data Format ● BCC Calculation Example The BCC (Block Check Character) is determined by calculating the exclusive OR of the bytes from the node number up to ETX. The 8-bit result is written to the BCC byte at the end of the frame. STX Node number Sub-address SID Command text ETX BCC 02H 0 (30H) 0 (30H) 0 (30H) 0 (30H) 0 (30H) 0 (30H)5 (35H) 0 (30H)3 (33H) 03H 35H CompoWay/F BCC = 30H+30H+30H+30H+30H+30H+35H+30H+33H+03H = 35H The result of the calculation (35 hex) is written to the BCC byte. The + symbols indicate XOR (exclusive OR) operations. ■ Response Frame Node number Sub-address End code Command text BCC STX 0 0 ETX 1 2 2 2 1 1 Error End Name Description detection code priority 00 Normal completion The command ended normally without error. None 0F FINS command error The specified FINS command could not be executed. 8 The FINS response code should indicate why the command could not be executed. 10 Parity error The sum total of bits whose received data is “1” does not 2 match the set value of the “communications parity” bit. 11 Framing error Stop bit is “0.” 1 12 Overrun error An attempt was made to transfer new data when the recep- 3 tion data buffer was already full. 13 BCC error The calculated BCC value is different from the received 5 BCC value. 14 Format error • The command text contains characters other than 0 to 9, 7 and A to F. This error does not apply to Echoback Tests. (Refer to the Echoback Test for details.) • There was no SID and command text. There was no com- mand text. • “MRC/SRC” not included in command text. 16 Sub-address error • Illegal (unsupported) sub-address 6 • There was no sub-address, SID, and command text. • Sub-address was less than two characters, and there was no SID and command text 18 Frame length error The received frame exceeds the specified (supported) num- 4 ber of bytes. • An end code is returned for each command frame received that was addressed to the local node. • No response will be returned unless the frame contained all elements up to the ETX and BCC. • “Error Detection Priority” indicates the priority when two or more errors occur simultaneously. 2-3

SECTION 2 CompoWay/F Communications Procedures ■ Communications Data Communications Set (monitor) Negative values Decimal point format values CompoWay/F 8-digit hexa- 2’s complement Decimal point is removed and the result is converted decimal to hexadecimal. Example conversion: 105.0 → 1050 → H’0000041A However, when reading or writing time data in hh.mm, mm.ss, or dd.hh, BCD data is used (the CompoWay/F same format as the display). Example: The data is H’00009959 for a display of 99.59. ■ End Code Example The following examples show the end code when a command did not end normally. Example 1) Illegal Sub-address, No SID, and No Command Text Command Node number Sub-address BCC STX 0 A EXT Response Node number Sub-address End code BCC STX 0 A 1 6 EXT End code is “16” (sub-address error). The sub-address error code is used because the sub-address error has a higher error detection priority than the format error. Example 2) No Command Text Command Node number Sub-address SID BCC STX 0 0 0 EXT Response Node number Sub-address End code BCC STX 0 0 1 4 EXT The end code is “14” (format error). Example 3) No Node Number Provided Command BCC STX EXT The node number is lacking one character. 2-4

Page 27

2.1 Data Format Response There is no response. Example 4) No Sub-address and Illegal BCC Command Node number BCC STX EXT Err CompoWay/F Response Node number Sub-address End code BCC STX 0 0 1 3 EXT The sub-address is “00” and the end code is “13” (BCC error). 2-5

SECTION 2 CompoWay/F Communications Procedures 2.2 Structure of Command Text ■ PDU Structure An MRC (Main Request Code) and SRC (Sub-Request Code) followed by the various required data is transferred to the command text. Service Request PDU CompoWay/F MRC SRC Data The MRES (Main Response Code) and SRES (Sub-Response Code) are transferred to the response frame following the above MRC/SRC. Data is then transferred following the MRES and SRES. Service Response PDU (Normal Response) MRC SRC MRES SRES Data If the specified command text could not be executed, the service response PDU will contain only the MRC/SRC and MRES/SRES. Service Response PDU (Command Text Not Executed) MRC SRC MRES SRES MRES/SRES provides the response code. MRES/SRES are not output when processing ends in a normal completion. ■ Area Definitions Areas comprise only the variable area. ■ Type Code (Variable Type) The following tables show the variable area type codes. Variable type (1 byte) MSB LSB 0 0 0 0 Access size Area 11: Double word 0: Setup area 0 10: Word 1: Setup area 1 2-6

Page 29

2.2 Structure of Command Text The following table summarizes setup areas 0 and 1. Area Description Setup area 0 This area groups together the protect, manual control, opera- tion, adjustment, program setting, and PID setting levels. Setup area 1 This area groups together the initial setting, communications setting, advanced function setting, and calibration levels. CompoWay/F The variable type depends on the parameter. Refer to 3.1 Variable Area (Setting Range) List. The variable type is converted to 2-byte ASCII and loaded to the frame. The following table shows the available variable types. Variable type Description C0/80 R/O (read only) parameter for setup area 0. C1/81 R/W parameter for setup area 0. C3/83 R/W parameter for setup area 1. C4/84 R/W parameters for setup area 0 (program setting level, currently selected number). C5/85 R/W parameter for setup area 0. DA/9A R/W parameters for setup area 0 (program setting level, all). Note: Setup area 1 has no read-only parameters, so there is no variable type “C2.” ■ Addresses An address is appended to each of the variable types. Express addresses in 2-byte hexadecimal and append them for the specified access size. The address depends on the parameter. Refer to 3.1 Variable Area (Setting Range) List. ■ Number of Elements The number of elements is expressed in 2-byte hexadecimal. The range that can be specified for the number of elements depends on the command. Refer to 2.3 Detailed Description of the Services for details. ■ List of Services MRC SRC Name of service Processing 01 01 Read Variable Area This service reads from the variable area. 01 02 Write Variable Area This service writes to the variable area. 01 04 Composite Read from This service reads from the variable Variable Area area in the order specified by the parameters. 2-7

Page 43

2.3 Detailed Description of the Services (3) Operation Commands and Precautions ● Communications Writing Set the Communications Writing parameter to “ON: enabled” or “OFF: disabled” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur, however, if enabling or disabling communications writing is set for an event input. CompoWay/F ● Run/Reset Set control to “run” or “stop” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. ● AT Execute/Cancel Set AT (auto-tuning) to “execute” or “cancel” with the related information setting. This command can be accepted in setup area 0 only. An “operation error” will be generated in the following instances: • When the Run/Reset parameter is set to Reset (and the reset operation is set to stop control). • During standby status (when the reset operation is set to stop control). • During manual operation or when executing from setup area 1. • When ON/OFF control is being used • When 40% AT is specified during 100% AT execution. • When 100% AT is specified during 40% AT execution. • When 100% AT execute/cancel or 40% AT execute/cancel is assigned to an event input. In addition, a parameter error will occur if 40% AT is specified during heating and cooling control or during position-proportional floating control. Note: If the same type of AT execution is specified during AT execution (e.g., if 100% AT is specified during 100% AT execution), the AT will not be restar ted and the operation will end in normal completion with no processing. ● Write Mode Set either the backup mode or RAM write mode with the related infor- mation setting. The setting can be accepted in both setup area 0 and setup area 1. The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when frequently overwriting data. 2-21

Page 44

SECTION 2 CompoWay/F Communications Procedures Write mode Description Backup mode The data is written to non-volatile memory when a parameter in the operation, program setting, adjust- ment, or PID setting level (excluding read-only parameters) is written using communications. RAM write mode The data is not written to non-volatile memory when a parameter in the operation, program setting, CompoWay/F adjustment, or PID setting level (excluding read-only parameters) is written using communications. Parameters can be changed by using key operations on the front panel of the Controller. • When the mode is changed from RAM write mode to backup mode, the parameters in the operation, program setting, adjustment, or PID setting level (excluding read-only parameters) are written to non-volatile memory. • RAM write mode is enabled only when communications are enabled in the Communications Writing parameter (i.e., set to ON). Therefore, if the Communications Writing parameter is changed to OFF (disabled), the parameter settings from the operation, program setting, adjustment, and PID setting levels (excluding read-only parameters) are written to non-volatile memory even if the RAM write mode is set. ● Save RAM Data This command writes the parameters in the operation, program setting, adjustment, or PID setting levels (excluding read-only parameters) to non-volatile memory. The setting can be made in either setup area 0 or setup area 1. ● Software Reset Restarts processing from the point when power is turned ON. The setting can be accepted in both setup area 0 and setup area 1. ● Move to Setup Area 1 This command moves to “setup area 1” and can be accepted at both setup areas 0 and 1. If the “initial setting/communications protect” is set to “2,” an “operation error” will be generated, and the move to setup area 1 will be prohibited. When this move is carried out from setup area 0, the display indicates the Input Type parameter in the “initial setting level.” When this operation command is executed in setup area 1, the display will not change. 2-22

Page 45

2.3 Detailed Description of the Services ● Move to Protect Level This command moves to the “protect level” and can be accepted only in setup area 0.When this command is issued in setup area 1, an “operation error” will be generated, and the move to the protect level will be prohibited. ◆ Moving to Protect Level in Manual Mode When this operation command is issued in manual mode, an CompoWay/F “operation error” will be generated, and the move to the protect level will be prohibited. ● Auto/Manual Switch This operation command switches the mode to manual mode or automatic mode, based on the related information setting. This command can be accepted in setup area 0 only. An “operation error” will be generated in the following instances: • When the command is executed in “setup area 1" • When auto/manual switching is disabled (not displayed) When the Controller is switched to manual mode, the “manual manipu- lated variable” will be displayed. When the Controller is switched from manual mode to automatic mode, the operation level’s first parameter will be displayed. When the Controller is switched to manual mode while already in manual mode, the command will be completed normally and the display will not change (the contents will not be refreshed). Note: When the auto/manual mode is switched with an operation command through communications and the Controller is in RAM write mode, the auto/manual status is not stored in non-volatile memory. Consequently, if the Controller is restarted by performing a software reset or turning the power OFF and ON again, the auto/manual mode is set to the last saved status. ◆ Switching to Manual Mode during Auto-tuning If the mode is switched during auto-tuning (AT), the AT will be cancelled and the Controller will be switched to manual mode. ● Parameter Initialization The present settings are returned to the default values and written to non-volatile memory. This command can be accepted in setup area 1 only. When this command is issued in setup area 0, an “operation error” will be generated. 2-23

(These settings are the same as the ones used when “FACT” is selected for the setting data’s set value initial- ization.) CompoWay/F ● Alarm Latch Cancel The applicable alarm latch can be cleared with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur if communications writing is disabled or if an non-volatile memory error occurs. ● SP Mode Select program SP mode, remote SP mode, or fixed SP mode with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur in the following situations. • When AT is being executed. • When the SP Mode parameter is disabled (not displayed at the Controller). ● Invert Direct/Reverse Operation Inverting or not inverting direct/reverse operation can be selected with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. The related information specifications are written to non-volatile memory according to the write mode settings. An operation error will occur in the following situations: • When AT is being executed. • When inverting direct/reverse operation is set for an event input. • When executed in manual mode. ● Infrared Communications Use Select ON or OFF to enable or disable using infrared communications with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. ● Hold Turn the hold operation ON or OFF with the related information setting. The setting can be made only in setup area 0. An operation error will occur in the following situations. • When AT is being executed • During standby status 2-24

2.3 Detailed Description of the Services • During a reset or when continuing control at the end of operation • When Hold/Clear Hold is assigned to an event input ● Advance This operation command performs the advance operation. The setting can be made only in setup area 0. An operation error will occur in the following situations. • When AT is being executed CompoWay/F • During standby status • During a reset or when continuing control at the end of operation ● Setting Areas Control operation is executed in setting area 0. In this state, you can perform operations that are permitted only during control or those that cause no problems even if control is in progress. These operations include reading PVs, writing SPs, and change Run/Reset status. Setting area 0, however, prohibits operations that affect control, including writing data at the initial setting level. (Reading setting data is always allowed.) In setting area 1, control operation is stopped. In this state, you can perform operations that are not allowed in setting area 0. These opera- tions include writing data at the initial setting level. At power-ON, the Digital Controller is set in setting area 0. To move to setting area 1, use the “move-to-setting area 1” command. To return to setting area 0, turn the power OFF and ON again, or use the “software reset” command. Power ON Software reset command Setting area 0 Setting area 1 “Move-to-setting area 1” command Control in progress Control stopped. 2-25

SECTION 4 Modbus Communications Procedure 4.1 Data Format The data format complies with the Modbus (RTU) communications protocol, so commands from the host and responses from the E5CN/ AN/EN-HT are contained in data blocks called frames. The structure of the command and response frames is described below. In the following explanations, hexadecimal values are expressed by adding the prefix H’ before the number, e.g., H’02. Numbers and alpha- betic characters without the H’ prefix are ASCII characters. ■ Command Frame When using RTU mode, start with a silent interval of at least 3.5 character times and end with a silent interval of at least 3.5 character times. Slave Function address code Data CRC-16 1 1 2 bytes Modbus CRC-16 calculation range Silent interval of 3.5 character times minimum. Specify the unit number. The unit number can be set between H’00 to H’63 hexadeci- Slave address mal (0 to 99 decimal). Specify H’00 for a broadcast transmission. No responses will be returned for broadcast transmissions. The function code is a 1-byte hexadecimal code that indicates Function code the type of command sent from the host device. This is the text data associated with the specified function Data code. Specify the required data, such as the variable address or setting data. (Set in hexadecimal.) Cyclical Redundancy Check This check code is calculated with the data from the slave CRC-16 address to the end of the data. The check code is 2-byte hexadecimal. Silent interval of 3.5 character times minimum. 4-2

4.1 Data Format ● CRC-16 Calculation Example Messages are processed one byte at a time in the work memory (a 16- bit register known as the CRC register). (1)The CRC register is initialized to H’FFFF. (2)An XOR operation is performed on the content of the CRC register and the first byte of the message, and the result is returned to the CRC register. (3)The MSB is packed with zeroes and the CRC register is shifted 1 bit to the right. (4)If the bit shifted from the LSB is 0, step 3 is repeated (next bit-shift processing). If the bit shifted from the LSB is 1, an XOR is performed on the content of the CRC register and H’A001, and the result is returned to the CRC register. (5)Steps 3 and 4 are repeated until 8 bits are shifted. (6)CRC processing continues to the end of the message, as XOR operations are performed on the content of the CRC register and the next byte of the message, step 3 is repeated, and the result is returned to the CRC register. (7)The result of the CRC calculation (value in the CRC register) is appended to the last byte of the message. Modbus Example of Appending the Calculation Result When the calculated CRC value is H’1234, the CRC value is appended to the command frame as follows. Slave Function address code Data CRC-16 Low High H'34 H'12 1 1 2 bytes CRC-16 calculation range 4-3

SECTION 4 Modbus Communications Procedure ■ Response Frame ● Normal Response Frame Slave Function address code Data CRC-16 1 1 2 bytes CRC-16 calculation range ● Error Response Frame Slave Function Error address code code CRC-16 1 1 1 2 bytes CRC-16 calculation range The number specified in the command frame is entered as-is. Slave address This is the unit number of the Unit returning the response. This is the received function code with the hexadecimal value of H’80 added to indicate that the response is an error Modbus response. Function code Example: Received function code = H’03 Function code in response frame when an error occurred = H’83 Error code This code indicates the kind of error that occurred. Cyclical Redundancy Check This check code is calculated with the data from the slave CRC-16 address to the end of the data. The check code is 2-byte hexadecimal. 4-4

4.1 Data Format ■ Error Codes Error End Name Description detection code priority H'01 Function code error An unsupported function code was received. 1 H'02 Variable address error The specified variable area address is out-of-range. 2 H'03 Variable data error The amount of data does not match the number of elements. 3 The byte count is not 2 times the number of elements. The response length exceeds the size of the communica- tions buffer. The command code or related information in the operation command is wrong or the write data is not in the setting range. H'04 Operation error The write data contents are not allowed in the present oper- 4 ation mode. ◆ The Communications Writing parameter is set to “OFF” (disabled). ◆ Attempted to write to a parameter in setup area 1 from setup area 0. ◆ Attempted to write to a protect parameter from other than the protect level. ◆ AT execution in progress ◆ The command cannot be processed. ● No Response Modbus In the following cases, the received command will not be processed and a response will not be returned. Consequently, a timeout error will occur at the host device. • The slave address in the received command does not match the communications unit number. • A parity error, framing error, or overrun error occurred due to a problem such as a transfer error. • A CRC-16 code error occurred in the received command frame. • There was a time interval of more than 3.5 character times between data packets that make up the command frame. Furthermore, the specified function’s processing will be performed but no response will be returned for broadcast functions (slave address = H’00). 4-5

4.3 Variable Area 4.3 Variable Area The variable area is the region of memory used to exchange data with the E5CN/AN/EN-HT through communications. Operations such as reading the process value and reading/writing parameters are performed on the variable area. On the other hand, operation commands do not use the variable area. E5CN/AN/EN-HT Operation Microcomputer commands, etc. Variable area Read/write When accessing the variable area, the position of a variable in the variable area is specified with a word identifier, area number, and address in the area. ● Addresses An address is appended to each of the variable types. Express addresses in 2-byte hexadecimal and append them for the specified access size. Each address is composed of a word identifier, area Modbus number, and address in the area. • Four-byte Mode Address (2 bytes) 0 0 0 * * * * * A 6 A 5 A 4 A 3 A 2 A1 A 0 0 Area number (00 to 18) Address in area (00 to FE): 128 variables Word identifier (0 to 3) • Two-byte Mode Address (2 bytes) 0 0 1 * * * * * 0 A 6 A 5 A 4 A 3 A 2 A1 A 0 Area number (20 to 38) Address in area (00 to 7F): 128 variables Word identifier (0 to 3) ◆ Modbus Addresses Corresponding to CompoWay/F Setup Areas 0 and 1 Setup area 0 and setup area 1 do not correspond directly to Modbus addresses, but the following areas have a rough correspondence with one exception. * Partial Exception to Modbus Address Correspondence 4-7

SECTION 4 Modbus Communications Procedure Modbus addresses Setup area Area number Address range Setup area 0 00 to 0B, 20 to 2B, 15, 0000 to 0BFE, 2000 to 2B7F, 18, 35, and 38 1500 to 15FE, 1800 to 1830, 3500 to 357F, and 3800 to 3818 Setup area 1 0C to 13 and 2C to 33 0C00 to 136C and 2C00 to 3336 The Hysteresis (Heating), Hysteresis (Cooling), Control Period (Heating), and Control Period (Cooling) parameters are assigned to consecutive addresses, but the control period parameters are setup area 1 parameters. For this reason, an operation error will occur when writing the control period (heating or cooling) from the setup area 0 side, e.g., from the operation level. ● Number of Elements The number of elements is expressed in 2-byte hexadecimal. The setting range for the number of elements varies according to the command. For example, when the number of elements is “0010,” this specifies eight items of data (H’10) from the address. • Four-byte Mode Modbus One element uses 2 bytes of data, so specify two-element units. Reading and writing in 4-byte units is executed by specifying an even address and specifying the number of elements in multiples of 2. • Two-byte Mode One element uses 2 bytes of data, so specify one-element units. Reading and writing in 2-byte data units is executed by specifying 1- element units. ● Set Values The values read from the variable area or written to the variable area are expressed in hexadecimal, ignoring the decimal point position. (Negative values are expressed in 2’s complement format.) Example: D’105.0 → H’0000041A The variables are 4-digit or 8-digit hexadecimal values. Negative values are expressed in 2’s complement format. The values are hexadecimal values with no decimal point indication. For example, if the E5CN/AN/EN-HT's process value is read in 4-byte mode when the process value is 105.0, the read value will be H'0000041A (105.0 → 1050 → H'0000041A). However, when reading or writing time data in hh.mm, mm.ss, or dd.hh, BCD data is used (the same format as the display). Example: The data is H’00009959 for a display of 99.59. 4-8

Command Frame Slave Function Read Number of address code start address Elements CRC-16 H'03 1 1 2 2 2 bytes Name Description Slave address Specify the E5CN/AN/EN-HT’s unit number. The unit number can be set between H’01 and H’63 hexadecimal (1 to 99 decimal). Function code The Read Variable Area function’s function code is H’03. Read start address Specify the address containing the data to be read. See SECTION 5 Communications Data for Modbus for details on addresses. Number of elements Four-byte Mode Modbus Specify 2 times the number of setting data items as the number of elements to be read. The setting range for the number of elements is H’0002 to H’006A (2 to 106). When H'006A is set, 53 items of setting data can be read. Example: When reading 2 items of setting data, set the number of elements to H’0004. Two-byte Mode Specify the number of setting data items to be read as the number of elements. The setting range for the number of elements is H'0001 to H'006A (1 to 106). When H'006A is set, 106 items of setting data can be read. Example: When reading two items of setting data, set the number of elements to H'0002. CRC-16 This check code is calculated with the data from the slave address to the end of the data.

The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur, however, if communications writing enable/ disable is set for an event input. ● Run/Reset Set control to “run” or “stop” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. 4-16

Page 89

4.4 Detailed Description of the Services ● AT Execute/Cancel Set AT (auto-tuning) to “execute” or “cancel” with the related information setting. This command can be accepted in setup area 0 only. An “operation error” will be generated in the following instances: • When the Run/Reset parameter is set to Reset (and the reset operation is set to stop control). • During standby status (when the reset operation is set to stop control). • In Manual Mode or when executing from setup area 1. • When ON/OFF control is being used • When 40% AT is specified during 100% AT execution. • When 100% AT is specified during 40% AT execution. • When 100% AT execute/cancel or 40% AT execute/cancel is assigned to an event input. In addition, a variable data error will occur if 40% AT is specified during heating and cooling control or during position-proportional floating control. Note: If the same type of AT execution is specified during AT execution (e.g., if 100% AT execution is specified dur ing 100% AT execution), the AT will not be restarted and the operation will end in normal completion with no processing. Modbus ● Write Mode Set either “backup mode” or “RAM write mode” with the related infor- mation setting. The setting can be accepted in both setup area 0 and setup area 1. The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when frequently overwriting data. Write mode Description Backup mode The data is written to non-volatile memory when a parameter in the operation, adjustment, program setting, or PID setting level (excluding read-only parameters) is written using communications. RAM write mode The data is not written to non-volatile memory when a parameter in the operation, adjustment, program setting, or PID setting level (excluding read-only parameters) is written using communica- tions. Parameters can be changed by using key operations on the front panel of the Controller. • When you switch from RAM Write Mode to Backup Mode, the param- eters in the operation, adjustment, program setting, and PID setting levels (excluding read-only parameters) are written to non-volatile memory. 4-17

Page 90

SECTION 4 Modbus Communications Procedure • RAM write mode is enabled only when communications are enabled in the Communications Writing parameter (i.e., set to ON). Therefore, if the Communications Writing parameter is changed to OFF (disabled), the parameter settings from the operation, adjustment, program setting, and PID setting levels (excluding read-only parameters) are written to non-volatile memory even if the RAM write mode is set. ● RAM Data This command writes the parameters in the operation, adjustment, program setting, and PID setting levels (excluding read-only param- eters) to non-volatile memory. The setting can be accepted in both setup area 0 and setup area 1. ● Software Reset Restarts processing from the point when power is turned ON. The setting can be accepted in both setup area 0 and setup area 1. ● Move to Setup Area 1 This command moves to “setup area 1” and can be accepted at both setup areas 0 and 1. If the “initial setting/communications protect” is set to “2,” an “operation error” will be generated, and the move to setup area 1 will be prohibited. Modbus When this move is carried out from setup area 0, the display indicates the “input type” in the “initial setting level.” When this operation command is executed in setup area 1, the display will not change. ● Move to Protect Level This command moves to the “protect level” and can be accepted only in setup area 0. When this command is issued in setup area 1, an “operation error” will be generated, and the move to the protect level will be prohibited. ● Auto/Manual Switch This operation command switches the mode to manual mode or automatic mode, based on the related information setting. This command can be accepted in setup area 0 only. An “operation error” will be generated in the following instances: • When the command is executed in “Setup Area 1” • When auto/manual switching is disabled (not displayed) When the Controller is switched to manual mode, the “manual manipu- lated variable” will be displayed. When the Controller is switched from manual mode to automatic mode, the operation level’s first parameter will be displayed. When the Controller is switched to manual mode 4-18

4.4 Detailed Description of the Services while already in manual mode, the command will be completed normally and the display will not change (the contents will not be refreshed). ◆ Switching to Manual Mode during Auto-tuning If the mode is switched during auto-tuning (AT), the AT will be cancelled and the Controller will be switched to manual mode. ● Parameter Initialization The present settings are returned to the default values and written to non-volatile memory. This command can be accepted in setup area 1 only. When this command is issued in setup area 0, an “operation error” will be generated. Related Explanation (initialization values) information 00 Default set values (See SECTION 3 Communications Data for CompoWay/F for details.) (These settings are the same as the ones used when “FACT” is selected for the setting data’s set value initialization.) ● Alarm Latch Cancel The applicable alarm latch can be cleared with the related information setting. The setting can be accepted in both setup area 0 and setup Modbus area 1. An operation error will occur if communications writing is disabled or if an non-volatile memory error occurs. ● SP Mode Select program SP mode, remote SP mode, or fixed SP mode with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur in the following situations. • When AT is being executed • When the SP Mode parameter is disabled (not displayed at the Controller) ● Invert Direct/Reverse Operation Inverting or not inverting direct/reverse operation can be selected with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. The related information specifications are written to non-volatile memory according to the write mode settings. An operation error will occur in the following situations: • When AT is being executed. • When inverting direct/reverse operation is set for an event input. • When executed in manual mode. 4-19

Page 92

SECTION 4 Modbus Communications Procedure ● Infrared Communications Use Select ON or OFF to enable or disable using infrared communications with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. ● Hold Turn the hold operation ON or OFF with the related information setting. The setting can be made only in setup area 0. An operation error will occur in the following situations. • When AT is being executed • During standby status • During a reset or when continuing control at the end of operation • When Hold/Clear Hold is assigned to an event input ● Advance This operation command performs the advance operation. The setting can be made only in setup area 0. An operation error will occur in the following situations. • When AT is being executed • During standby status • During a reset or when continuing control at the end of operation Modbus ● Setting Areas Control operation is executed in setting area 0. In this state, you can perform operations that are permitted only during control or those that cause no problems even if control is in progress. These operations include reading PVs, writing SPs, and changing Run/Reset status. Setting area 0, however, prohibits operations that affect control, including writing data at the initial setting level. (Reading setting data is always allowed.) In setting area 1, control operation is stopped. In this state, you can perform operations that are not allowed in setting area 0. These opera- tions include writing data at the initial setting level. At power-ON, the Digital Controller is set in setting area 0. To move to setting area 1, use the “move-to-setting area 1” command. To return to setting area 0, turn the power OFF and ON again, or use the “software reset” command. Power ON Software reset command Setting area 0 Setting area 1 “Move-to-setting area 1” command Control in progress Control stopped. 4-20
