4.1 Wiring
To prevent electric shock or instrument failure, do not turn on the power until all
the wiring is completed.
CAUTIONS
Power supply wiring:
WARNING
!
Use a power supply is within the power supply voltage variation range.
For power supply wires, use twisted wires with low voltage drop.
Separate each of the instrument power supply line, input/output circuit power supply line,
equipment and motor power supply line, and operating circuit power supply line.
If a noise source is near the instrument and could affect the instrument, use a noise
filter.
− Shorten the distance between twisted power supply wire pitches. The shorter the
distance between the pitches, the more effective for noise reduction. In addition,
always ground noise filter.
− Always install the noise filter on the grounded panel. Also minimize the wiring distance
between the noise filter output side and instrument power supply terminals to ensure
the effectiveness of the noise filter.
− Do not connect fuses or switches on the wiring of the noise filter output side, since
these may reduce the effectiveness of the noise filter.
− To obtain a satisfactory noise filter effect, select the most suitable type after due
consideration of instrument power supply voltage and filter frequency characteristics.
To the instrument with power supply of 24 V, please be sure to supply the power from
SELV circuit.
Grounding wire wiring:
Ground the instrument separately from other equipment. The grounding resistance should
be 100 Ω or less. Use grounding wires with a cross section area of 2.0 mm

5.4 Communication Data
5.4.1 Request command and data transfer
Data transfer between the PLC and RKC temperature controller are excuted by the request
command (Register area No. 20).
Request command “0: Monitor”
Command which requests the RKC temperature controller to write data items such as temperature
measured values, etc. (attribute: RO) to the PLC side. The COM-E always repeats data writing until
“1: Setting” or “2: Set value monitor” is set to the request command. The COM-E communication
status is set to “1: Writing on monitor data” during data transfer.
Data transfer procedures
[Example]
• Set “0: Monitor” to the request command on the PLC side.
• If the request command is set, the COM-E writes our temperature controller data items such as
temperature measured values, etc. (attribute: RO) into the PLC.
• The COM-E communication status is set to “1: Writing on monitor data” during data transfer.
PLC
1. The COM-E reads the request
command “0: Monitor” from the PLC.
COM-E
The COM-E always repeats
data read.
RKC temperature
controller
2. The COM-E writes RKC temperature
controller data items such as
temperature measured values, etc.
into the PLC.
Request command “1: Setting”
This is the command of making a request to our temperature controller for writing data items such as
temperature set values, etc. (attribute: RW) set to the resister on the PLC side (memory).
Data transfer procedures
[Example]
• Data items such as temperature set values, etc. (attribute: RW) are set to the resister on the PLC
side (memory).
• Set “1: Setting” to the request command on the PLC side.
Continued on the next page.
36
IMS01C01-E7
5. PLC COMMUNICATION
Continued from the previous page.
•
If the request command is set, the COM-E starts reading data items such as temperature set values,
etc. (attribute: RW) on the PLC side. The COM-E communication status is set to “2: Reading out
setting data” during data read on the PLC side.
• If the COM-E finishes reading data items from the PLC, it starts writing the data items read to our
temperature controller. The COM-E communication status is set to “2: Reading out setting data”
even during data write into our temperature controller.
• After the data is transferred, the request command and COM-E communication status returns
to “0: Monitor” and “1: Writing on monitor data,” respectively.

Data transfer procedures
[Example]
• Set “2: Set value monitor” to the request command on the PLC side.
• If the request command is set, the COM-E writes our temperature controller data items such as
temperature set values, etc. (attribute: RW) into the PLC.
The COM-E communication status is set to “3: Writing on setting data” during data transfer.
• After the data is transferred, the request command and COM-E communication status returns
to “0: Monitor” and “1: Writing on monitor data,” respectively.

5. PLC COMMUNICATION
5.4.2 Communication status check
The communication status between the PLC and COM-E is confirmed by the COM-E communication
status (Register area No. 21).
The COM-E always writes data on the COM-E communication status into the PLC.
COM-E communication status “0: Communication failure”:
“0: Communication failure” represents that communication between the COM-E and PLC is abnormal.
If communication between the COM-E and PLC is normal, the COM-E communication status
always becomes 1, 2, or 3.
COM-E communication status “1: Writing on monitor data”:
“1: Writing on monitor data” represents that data items such as temperature measured values, etc.
(attribute: RO) are being written into the PLC.
COM-E communication status “2: Reading out setting data”:
“2: Reading out setting data” represents that data items such as temperature set values, etc. (attribute:
RW) are being read from the PLC.
COM-E communication status “3: Writing on setting data”:
“3: Writing on setting data” represents that data items such as temperature set values, etc. (attribute:
RW) are being written into the PLC.
Communication status check procedures
[Example]
When the COM-E communication status is “1: Writing on monitor data”
1. “0: Communication failure” is set to the register on the PLC side (COM-E communication
status).
Conduct this setting only when checking the communication status.
2. After setting, take appropriate wait time.
Wait time differs depending on the connectable number of our temperature controllers.
It is about 1 second/controller.
3. After a lapse of wait time, confirm that the value in the register on the PLC side (COM-E
communication status) is “1: Writing on monitor data.”

• Binary digit: 00000000 00000100
• Hexadecimal numeral: 0004H
• Decimal numeral: 4
(2) The data type is treated as binary data with a sign and without a decimal point. For this reason,
carefully express and set the data.
[Example] Proportional band setting
Initial value of internal data: 3.0
Communication data: 30
(3) Any item whose attribute is RO (Read only) is always written to the PLC from the
COM-E.
During data write, “1: Writing on monitor data” is written to “COM-E communication status.”
(The RKC temperature controller
→ COM-E → PLC)
(4) Any item whose attribute is R/W (Read and Write) is read only when “Request command” is set to
“1: Setting.”
→ COM-E → The RKC temperature controller)
(PLC
(5) Any item whose attribute is R/W (Read and Write) is written only when “Request command” is set
to “2: Set value monitor.” After finish writing, “COM-E communication status” is set to “1:
Writing on monitor data”, “Request command” is set to “0: Monitor.”
(The RKC temperature controller
→ COM-E → PLC)
(6) The autotuning (AT) function is activated when “AT startup/stop” is set to “1: Autotuning (AT)
startup” and “A request for reading out set value” is set to “1: Reading out set value.” After the
autotuning (AT) function is finished, the
COM-E sets “2: Writing on set value” to “A request for
reading out set value” to write each set value to the PLC. At this time, “AT startup/stop” returns
to “0: Autotuning (AT) end or stop” to change the PID constants.

6. HOST COMMUNICATION
6.1 Protocol
RKC communication uses the polling/selecting method to establish a data link. The basic procedure is
followed ANSI X3.28 subcategory 2.5, B1 basic mode data transmission control procedure (Fast
selecting is the selecting method used in COM-E).
• The polling/selecting procedures are a centralized control method where the host computer controls the entire
process. The host computer initiates all communication so the controller responds according to queries and
commands from the host.
• The code use in communication is 7-bit ASCII code including transmission control characters.
Transmission control characters used in COM-E:
EOT (04H), ENQ (05H), ACK (06H), NAK (15H), STX (02H), ETB (17H), ETX (03H)
( ): Hexadecimal

ENQ
IMS01C01-E7
6. HOST COMMUNICATION
2. Identifier (2 digits)
The identifier specifies the type of data that is requested from the RKC temperature controller.
Always attach the ENQ code to the end of the identifier.
See 6.2 Communication Identifier List (P. 62).
3. ENQ
The ENQ is the transmission control character that indicates the end of the polling sequence. The
host computer then must wait for a response from the COM-E.
(3) Data sent from the COM-E
If the polling sequence is received correctly, the COM-E sends data in the following format:
Identifier Data BCCETBSTX
Identifier Data BCCETXSTX
If the length of send data (from STX to BCC) exceeds 128 bytes, it is divided into blocks by
ETB. In this case, the succeeding divided data is sent after STX.
1. STX
STX is the transmission control character which indicates the start of the text transmission
(identifier and data).
2. Identifier (2 digits)
The identifier indicates the type of data (measured value, status and set value) sent to the host
computer.
See 6.2 Communication Identifier List (P. 62).
3. Data
Data which is indicated by an identifier of this instrument, consisting of channel numbers, data,
etc. Each channel number and data are delimited by a space (20H). The data and the next channel
number are delimited by a comma.
• Channel number: 2-digit ASCII code, not zero-suppressed.
In this specification, the value obtained by adding “1” to the device address
of the controller becomes the channel number.
• Data: ASCII code, zero-suppressed with spaces (20H). The number of digits varies
depending on the type of identifier.

6. HOST COMMUNICATION
4. ETB
Transmission control character indicating the end of the block.
5. ETX
Transmission control character indicating the end of the text.
6. BCC
BCC (Block Check Character) detects error using horizontal parity and is calculated by
horizontal parity (even number).
Calculation method of BCC: Exclusive OR all data and characters from STX through ETB or
ETX, not including STX.
Example:
STX M 1 0 1 1 5 0 . 0 ETX BCC
4DH 31H 30H 31H 20H 20H 31H 35H 30H 2EH 30H 03H
Hexadecimal numbers
BCC = 4DH ⊕ 31H ⊕ 30H ⊕ 31H ⊕ 20H ⊕ 20H ⊕ 31H ⊕ 35H ⊕ 30H ⊕ 2EH ⊕ 30H ⊕ 03H = 54H
( ⊕: Exclusive OR)
Value of BCC becomes 54H
(4) EOT send (Ending data transmission from the COM-E)
In the following cases, the COM-E sends EOT to terminate the data link:
• When the specified identifier is invalid
• When there is an error in the data format
• When all the data has been sent
(5) No response from the COM-E
The COM-E will not respond if the polling address is not received correctly. It may be necessary for
the host computer to take corrective action such as a time-out.
(6) NAK (Negative acknowledge)
If the host computer does not receive correct data from the COM-E, it sends a negative
acknowledgment NAK to the COM-E. The COM-E will re-send the same data when NAK is received.
This cycle will go on continuously until either recovery is achieved or the data link is corrected at the
host computer.
56
IMS01C01-E7
6. HOST COMMUNICATION
(7) No response from host computer
When the host computer does not respond within approximately three seconds after the COM-E sends
data, the COM-E sends EOT to terminate the data link (time-out time: about 3 seconds).
(8) Indefinite response from host computer
The COM-E sends EOT to terminate the data link when the host computer response is indefinite.
(9) EOT (Data link termination)
The host computer sends EOT message when it is necessary to suspend communication with the
COM-E or to terminate the data link due lack of response from the COM-E.

The host computer sends data for the selecting sequence with the following format:
3.2. 6.4.1.
Identifier Data BCCETBSTX
Identifier Data BCCETXSTX
or
3.2. 6.5.1.
If the length of send data (from STX to BCC) exceeds 128 bytes, it is divided into blocks by
ETB. In this case, the succeeding divided data is sent after STX.
Details for 1 to 6, see 6.1.2 Polling (P. 53).
(4) ACK (Acknowledgment)
An acknowledgment ACK is sent by the COM-E when data received is correct. When the host
computer receives ACK from the COM-E, the host computer will send any remaining data. If there is
no more data to be sent to COM-E, the host computer sends EOT to terminate the data link.
(5) NAK (Negative acknowledge)
In the following cases, the COM-E sends NAK. Then the appropriate recovery processing steps should
be taken , such as resending the data on the host computer side.
• When an error occurs on the line (parity error, framing error, etc.)
• When a BCC check error occurs
• When the specified identifier is invalid
• When there is an error in the data format
• When receive data exceeds the setting range
(6) No response from SR Mini HG SYSTEM
The COM-E does not respond when it can not receive the selecting address, STX, ETB, ETX or BCC.
(7) EOT (Data link termination)
The host computer sends EOT when there is no more data to be sent from the host computer or there is
no response from the COM-E.

If the power is supplied simultaneously to the PLC and
COM-E, the ERR indicator * on the Q Corresponding Serial
Communication Module (QJ71C24) side of the PLC lights.
This is because the COM-E sends the BRK (break) signal to
the PLC for about 10 seconds, but not abnormal.
* When the ERR indicator turn on once, it is held.
For details of error reset, see the Users Manual (Basic) for the Q
Corresponding Serial Communication Module and the Operating
Manual for the GX Developer .
Checking initial communication
If 1 (writing on monitor data) is set to D5881 (COM-E
communication status) the wait time after 0 (monitor) is set to
D5880 (request command) in the PLC, our temperature controller
communicates normally with the PLC to indicate that our temperature
controller data items such as temperature measured values,
etc. (attribute: RO) are being written into the PLC.
Sets the number of our temperature controllers used in this system.
