4.3 Communication Requirements
Processing times during send/receive
The SR Mini HG SYSTEM required the following processing
times during data send/receive.
Whether the host computer is using either the polling or selecting
procedure for communication, the following processing times are
required for SR Mini HG SYSTEM to send data:
-Response wait time after SR Mini HG SYSTEM sends BCC in
polling procedure
-Response wait time after SR Mini HG SYSTEM sends ACK or
NAK in selecting

In addition, in status of the following, there is not
communication between a little.
AT end: About 0.8 seconds
Setting of initial setting item: About 0.8 to 3 seconds
Fail-safe
A transmission error may occur with the transmission line
disconnected, shorted or set to the high-impedance state. In
order to prevent the above error, it is recommended that the
fail-safe function be provided on the receiver side of the host
computer. The fail-safe function can prevent a framing error from
its occurrence by making the receiver output stable to the MARK
“1” when the transmission line is in the high-impedance state.
5. PROTOCOL
RKC communication uses the polling/selecting method to
establish a data link. The basic procedure is followed ANSI
X3.28-1976 subcategories 2.5 and B1 basic mode data
transmission control procedure (Fast selecting is the selecting
method used in SR Mini HG SYSTEM).
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 SR Mini HG SYSTEM:
EOT (04H), ENQ (05H), ACK (06H), NAK (15H), STX (02H),
ETB (17H), ETX (03H)
( ): Hexadecimal
5.1 Polling
Polling is the action where the host computer requests one of the
connected SR Mini HG SYSTEM to transmit data. An example of
the polling procedure is shown below:

2. Identifier (2 digits)
The identifier specifies the type of data that is requested from
the SR Mini HG SYSTEM. Always attach the ENQ code to
the end of the identifier.
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 SR Mini HG SYSTEM.
(3) Data sent from the SR Mini HG SYSTEM
If the polling sequence is received correctly, the SR Mini HG
SYSTEM sends data in the following format:
Identifier Data BCCETBSTX
3.2. 6.4.1.
Identifier Data BCCETXSTX
3.2. 6.5.1.
or
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.
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. Channels
without channel numbers may exist depending on the
type of identifier.
Data:
ASCII code, zero-suppressed with spaces (20H). The
number of digits varies depending on the type of identifier.
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

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
SR Mini HG SYSTEM)
In the following cases, the SR Mini HG SYSTEM 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 SR Mini HG SYSTEM
The SR Mini HG SYSTEM 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) ACK (Acknowledgment)
An acknowledgment ACK is sent by the host computer when
data received is correct. When the SR Mini HG SYSTEM
receives ACK from the host computer, the SR Mini HG SYSTEM
will send any remaining data of the next identifier without
additional action from the host computer.
For the identifier, refer to 6. COMMUNICATION
IDENTIFIER LIST (P. 8).
When host computer determines to terminate the data link, EOT
is sent from the host computer.
(7) NAK (Negative acknowledge)
If the host computer does not receive correct data from the SR
Mini HG SYSTEM, it sends a negative acknowledgment NAK to
the SR Mini HG SYSTEM. The SR Mini HG SYSTEM 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.
(8) No response from host computer
When the host computer does not respond within approximately
three seconds after the SR Mini HG SYSTEM sends data, the
SR Mini HG SYSTEM sends EOT to terminate the data link
(time-out time: about 3 seconds).
(9) Indefinite response from host computer
The SR Mini HG SYSTEM sends EOT to terminate the data link
when the host computer response is indefinite.
(10) EOT (Data link termination)
The host computer sends EOT message when it is necessary to
suspend communication with the SR Mini HG SYSTEM or to
terminate the data link due lack of response from the SR Mini
HG SYSTEM.
5.2 Selecting
Selecting is the action where the host computer requests one of
the connected SR Mini HG SYSTEM to receive data. An

any remaining data. If there is no more data to be sent to SR
Mini HG SYSTEM, the host computer sends EOT to terminate
the data link.
(5) NAK (Negative acknowledge)
If the SR Mini HG SYSTEM does not receive correct data from
the host computer, it sends a negative acknowledgment NAK to
the host computer. Corrections, such as re-send, must be made
at the host computer. The SR Mini HG SYSTEM will send NAK
in the following cases:
When an error occurs on communication the line (parity,
framing error, etc.)
When a BCC check error occurs
When the specified identifier is invalid
When receive data exceeds the setting range
(6) No response from SR Mini HG SYSTEM
The SR Mini HG SYSTEM 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 SR
Mini HG SYSTEM.
The operation panel (OPC*) can correspond not only to
SR Mini HG SYSTEM communication but also to
programmable controller (PLC) communication (optional).
The PLC communication control procedure differs from
the SR Mini HG SYSTEM communication control
procedure and also from the procedure for communication
between each programmable controller manufactured by
the respective company. Therefore, in order to
discriminate PLC communication from SR Mini HG
SYSTEM communication, the former uses the identifier
(CP) dedicated to it. The PLC communication protocol
especially for the respective company is used after the
identifier (CP).

6. COMMUNICATION IDENTIFIER LIST
If you add or delete a function module, or change the arrangement of the modules, or replace a module with a different
model, be sure to perform “Module initialization (identifier CL)” before setting the data.
“Module initialization” stores the new module configuration in the H-PCP module.
If data is set before “Module initialization” is performed, the H-PCP module will set the previously stored initial data of the
old modules in the new modules, which may cause malfunction.
For details on how to initialize the module, refer to SR Mini/SR Mini HG SYSTEM Supplementary Information
Initialize Settings [Extended Communications] (IMSRM07-E).
The above manuals can be downloaded from the official RKC website:
http://www.rkcinst.com/english/manual_load.htm
Note that there are identifiers which indicate that communication is not possible depending on the specification.

aProbable causes of occurrence
When errors 1, 2 or 5 have occurred, a breakdown in the RAM, ROM or A/D converter should be suspected.
Error 3 occurs when the module structure is different from the initial structure. An example would be if a module is replaced by a
different model of module. In this situation, replace with the same model of module. Further, this error will also occur when module
initialize has not been carried out after changing the module structure.
Error 4 occurs in the situation where a module is removed while the power is still on, etc.
If errors 5 or 6 occur, there is a possibility that too much noise, surge or strong shock has been applied to the control unit.
bAutotuning (AT) is the function which automatically measures, calculates and sets the optimum PID constants according to the set
temperature.
Caution for using the Autotuning (AT)
When a temperature change (UP and/or Down) is 1 C or less per minute during Autotuning, Autotuning may be
cancelled before calculating PID values. In that case, adjust the PID values manually. Manual setting of PID values
may also be necessary if the set value is around the ambient temperature or is close to the maximum temperature
achieved by the load.
The following is the conditions necessary to carry out autotuning and the conditions which will cause the autotuning to stop.
[Conditions necessary for autotuning]
The autotuning should be executed after satisfying all of the following conditions:
Operation mode conditions:
Auto/Manual transfer (Identifier J1) →Auto mode
PID/AT transfer (Identifier G1) →PID control mode
Control RUN/STOP transfer (Identifier SR) →Control RUN mode
The measured value (PV) is without input error range [Input error determination point (high) Measured value (PV) Input
error determination point (low)].
The output limiter high limit should be more than 0.1 % and the output limiter low limit should be less than 99.9 %.
When operation mode (Identifier EI) is set to “Normal (Can be controlled).”
When the autotuning is finished, the display of each channel automatically returns to “0: PID control operation.”
[Conditions which will cause the autotuning to stop]
When the temperature set value (SV) is changed.
When the memory area is changed.
When the PV bias value is changed.
When the AT bias value is changed.
When transfer to Manual mode using the Auto/Manual transfer.
When the measured value (PV) goes to input error range [Measured value (PV) Input error determination point (high) or
Input error determination point (low) Measured value (PV)].
When the power is cut off.
When FAIL occurs in the module whose channel is under the autotuning. Otherwise, when FAIL occurs in the H-PCP-A/B
module.
When transfer to the PID control mode by the PID/AT transfer.
When operation mode is set to “Unused,” “Monitor” or “Alarm.”
When the Control RUN/STOP function is changed to the “Control STOP” function.
When the above-mentioned conditions to stop the autotuning occurs, the autotuning is immediately stopped and
switch over to the PID control mode. The PID constants return to the values at the start of the autotuning.

7. TROUBLESHOOTING
This section lists some basic causes and solutions to be taken when any problem would arise in this instrument. If you cannot solve a
problem, please contact RKC sales office or the agent, on confirming the type name and specifications of the product.
If the instrument is necessary to be replaced, observe the following warning.
All wiring must be completed before power is turned on to prevent electric shock, instrument failure, or incorrect action.
The power must be turned off before repairing work for input break and output failure including replacement of sensor,
contactor or SSR, and all wiring must be completed before power is turned on again.
If you add or delete a function module, or change the arrangement of the modules, or replace a module with a different
model, be sure to perform “Module initialization (identifier: CL)” before setting the data.
“Module initialization” stores the new module configuration in the H-PCP module.
If data is set before “Module initialization” is performed, the H-PCP module will set the previously stored initial data of the
old modules in the new modules, which may cause malfunction.
For details on how to initialize the module, refer to SR Mini/SR Mini HG SYSTEM Supplementary Information
Initialize Settings [Extended Communications] (IMSRM07-E).
The above manuals can be downloaded from the official RKC website: http://www.rkcinst.com/english/manual_load.htm
As all data on PID constants, alarm set values, etc. is managed by the H-PCP module, it is necessary to re-enter and
re-set all data when the H-PCP module is replaced.
However, re-entry and re-set are not required in the following cases.
When data backup software is operating in the module by the external host computer.
When it is set on the operation panel so that data on the operation panel side is transferred to the control unit side
when the power is turned on again.
RKC communication
Problem Possible cause Solution
No response Wrong connection, no connection or disconnection of the
communication cable Confirm the connection method or condition and connect correctly
Breakage, wrong wiring, or imperfect contact of the
communication cable Confirm the wiring or connector and repair or replace the wrong one
Mismatch of the setting data of communication speed
and data bit configuration with those of the host
computer
Confirm the settings and set them correctly
Wrong address setting
Error in the data format Reexamine the communication program
Transmission line is not set to the receive state after
data send (for RS-485)
EOT return The specified identifier is invalid Confirm the identifier is correct or that with the correct
function is specified. Otherwise correct it
Error in the data format Reexamine the communication program
NAK return Error occurs on the line (parity bit error, framing error,
etc.) Confirm the cause of error, and solve the problem
appropriately. (Confirm the transmitting data, and resend
data)
BCC error
The data exceeds the setting range Confirm the setting range and transmit correct data
The block data length of the transmission exceeds 128
bytes Divide the block using ETB before sending it
The specified identifier is invalid Confirm the identifier is correct or that with the correct
function is specified. Otherwise correct it
The transmission mode of the operation panel is set to
local mode Change to computer mode
CAUTION
To prevent electric shock or instrument failure, always turn off the system power before replacing the
instrument.
To prevent electric shock or instrument failure, always turn off the power before mounting or removing the
instrument.
To prevent electric shock or instrument failure, do not turn on the power until all wiring is completed. Make sure
that the wiring is correct before applying power to the instrument.
To prevent electric shock or instrument failure, do not touch the inside of the instrument.
All wiring must be performed by authorized personnel with electrical experience in this type of work.
