1. Safety rules
Safety rules, precautions concerning equipment damage, additional instructions and notes are written based on the
following headings.
WARNING: Matters that could result in injury or death if instructions are not followed.
CAUTION: Matters that could result in equipment damage if instructions are not followed.

WARNING
The SRS10 Series digital controllers are manufactured and designed to
control temperature, humidity and other physical amounts for general
industrial equipment. You should therefore avoid using the devices for
control that could have a serious effect on human life. It is the customer's
responsibility to take measures to ensure safety. Shimaden shall not be
liable for accidents resulting from failure to take proper safety measures.
If the controller is mounted inside a control box, etc., be sure to take
measures so the terminal element is not touched by any part of the
human body.
Do not open the case, touch the pc board, or stick your hands or any
electrical conductor inside the case. Do dot attempt to repair or modify
the equipment yourself. Doing so could result in electric shock accident
involving death or serious injury.

CAUTION
If there is danger of damage to any peripheral device or equipment due to
failure of the controller, you should take appropriate safety measures
such as mounting a fuse or overheating prevention device. Shimaden
shall not be liable for accidents resulting from failure to take proper safety
measures.
Be sure to read the safety precautions in the instruction manual
thoroughly and get a good understanding of the contents before
attempting to use the equipment.

2. Overview
2-1. Communication interface
With the SRS10 Series, RS-485 communications is optionally available. With this option, you can set and read
various types of data using the RS-485 interface.
RS-485 is the data communications standard established by the Electronic Industries Association of the U.S. (EIA).
This standards stipulate the hardware. The data transmission procedure software is however not defined, so
communication cannot be carried out unconditionally with another device equipped with the same interface. The
customer must therefore get a good understanding of data transmission specifications and procedures prior to using
the equipment.
Using the RS-485 interface enables you to connect multiple SRS10 Series controllers in parallel. Few PC models
currently support the RS-485 interface, but if you equip your machine with a commercially available RS-485
converter, you can use the RS-485 interface.

3. Controller and host computer connection

A transmission data line and a reception data line are connected between the SRS10 Series controller and host
computer. A connection example is provided below. For details see the host computer manual.

3-1. RS-485
The input/output logic level of the SRS10 Series is basically as follows.
Mark
- terminal < + terminal
Space
- terminal > + terminal
The + and - terminals of the controller are however high impedance up until immediately before transmission begins
and the level described above is output immediately before transmission starts. (See 3-2. 3-State output control.)

Note 1: With RS-485 specifications, you should mount the 1/ 2W

120 terminating resistor that comes with the terminal
element (between + and -) if necessary.
The terminating resistor should however be ultimately
mounted on a single controller only.
Operation cannot be guaranteed if a terminating resistor
is mounted on more than one controller.

3-2. 3-State output control

Because RS-485 is a multidrop system, in order to avoid collision of transmitted signals, transmission is always high
impedance if communication is not conducted or during reception. Status changes from high impedance to communication
output immediately prior to transmission, and is once again controlled to high impedance as soon as transmission is
complete.
However, because 3-state control is delayed approximately 1 msec after end bit transmission of end character is finished,
you should provide several msec of delay time when starting transmission immediately after the host receives the transmission.

4. Settings related to communication

There are 12 types of parameters related to communication for the SRS10 Series as follows. The parameters cannot
be set or modified by communication; use the keys on the front panel to set or modify the parameters.
When setting the parameters, you should follow the procedure as described in Description and Settings for 6 screens in
the instruction manual.

4-1. Communication mode settings

4-32

Initial value: Loc

Setting range: Loc, Com
The following selections can be made for communications. Can be changed only from Com to Loc with the front panel keys.

4-2. Communication address settings

4-33

Initial value: 1
Setting range: MAST, 1 255
Because it is a multidrop system, connection up to 1 - 31 (max.) is possible.
With this system, each machine is provided with an address (machine No.) to distinguish it so only the machine of the
specified address can be handled. When set to MAST, the machine operates as the master.

Note 1: Address can be set to 1 - 255. Up to 31 machines can be connected.

4-3. Communication data format settings

4-37

Initial value: 9600 bps

Setting range: 1200, 2400, 4800, 9600, 19200, 38400 bps
Selects/sets communication speed to transmit data to the host.

4-7. Delay time setting

4-38

Initial value: 20
Setting range: 1 100
You can set delay time from when communication command is received until transmission.
Delay time (msec) = Setting value (count) x 0.512 (msec)

Note 1: In the case of RS-485, it may take a while for 3-state control by line converter and signal collision may occur in some cases.

This can be avoided by increasing delay time. Caution is required particularly if communication speed is slow (1200/2400 bps, etc.).

Note 2: Actual delay time from when the communication command is received until transmission is the total of the delay time and

time it takes software to process the command. Especially in the case of a write command, it may take about 400 msec to
process the command.

4-8. Communication memory mode settings

4-39

Initial value: EEP

Setting range: EEP, Ram, r_E
Because the write cycle of the non-volatile memory (EEPROM) used by the SRS10 Series is decided, the life of the
EEPROM will be shortened if the SV data is frequently replaced by communications.
In order to prevent this, set to RAM mode when data is to be frequently replaced during communications, so that RAM
data can be replaced rather than replacing the data in the EEPROM, thereby extending the life of the EEPROM.
Selection

Processing contents

EEP

Mode whereby EEPROM data is also replaced when data is changed by communications.
Consequently data is preserved even if the power is turned off.
Mode whereby only RAM data is replaced instead of replacing EEPROM data if data is
changed by communications. Consequently the data in the RAM is cleared when the
power is turned off. When the power is turned back on, operation boots by the data
stored in the EEPROM.
SV and OUT data is written in the RAM only; other data is written in the RAM or
EEPROM.

r_E

* Caution when in communication memory mode RAM

If RAM is set for communication memory mode, all of the descriptions which are set by the communication function are only
written for RAM.
Therefore, non-matching can result according to the setting description.
Example: if the measuring range is set to 05: K 0.0-800.0
1. Change event code from higher limit deviation alarm to higher limit absolute alarm by using the communication function, then
change the communication mode from COM to LOC.
2. Change the event point from 800.0 to 700.0 by key operation. (Written to EEPROM as this is the key operation.)
3. Shut down the power, then restart.
4. 700.0 is the read-out as although the event code changes by communication function back to the higher limit deviation alarm, the
event action point changed by key operation conducts writing to EEPROM.
5. The action point setting range of the higher limit deviation alarm is originally -199.9-200.0.
However, 700.0, abnormal value, is set as a value in this case. Therefore, it should be modified to the normal range of value.

4-9. Master mode setting

Sets slave side communication address for which data is to be replaced when in the master mode.
Displayed when in the master mode.

5. Overview of shimaden communication protocol

The SRS10 Series uses Shimaden communication protocol.
For this reason, data acquisition can be changed by same communication format even if machine of different series
using Shimaden communication protocol is connected.

5-1. Communication procedure

(1) Master-slave relationship
PC and PLC (host) side are on the master side.
The SRS10 Series is on the slave side.
Communication is started by communications command from the master side and ends by communication response
from the slave side.
There is however no communication response if an error such as communication format error or BCC error is recognized.
There is also no communication response for broadcast command as well.

(2) Communication procedure

Communication procedure calls for slave side responding to master side, with mutual transmission authority.

(3) Time out

The controller times out if end character reception is not completed within 1 second after receiving the start character,
and begins waiting for another command (new start character).
Therefore set at least 1 second at the time out time on the host side.

5-2. Communication format

Because the SRS10 Series supports various types of protocol, you can make a wide range of selections by
communication format (control code and BCC operating method) and communication data format (data bit length,
parity or no parity, stop bit length).
But for the sake of convenience and in order to avoid confusion when making communication settings, we
recommend using the following format.
Recommended format
STX_FTX_CR
ADD
7E1

BCC operating method
Communication data format

(1) Communication format overview

The communication command format sent from the master and communication response format sent from the slave
consist of 3 blocks: basic format portion I, text portion, and basic format portion II.
Basic format portions I and II share read command (R) and write command (W) for communication response.
Operation results data is however inserted for BCC data of i (13 and 14) as it occurs.
Text portion differs according to command type, data address and communication response.

a: Start character [c: 1 digit/STX (02H) or @ (40H)]

Indicates start character of communication string.

When start character is received, it is judged to be the first character of a new communication string.
Start character and text end character are selected as a pair.
Selected by STX ( 02H ) - - - ETX (03H)
Selected by ( 40H ) - - - (3AH)
b: Machine address [d,

e: 2 digits]

Specifies machine to carry out communication.

Address is specified in the range of 1 - 255 (decimal notation)
Binary 8-bit data (1: 0000 0001 - 255: 1111 1111) is divided into top 4 bits and bottom 4 bits and converted to ASCII data.
d: Top 4 bits is data converted to ASCII.
e: Bottom 4 bits is data converted to ASCII.
Machine address = 0 (30H, 30H) is used for broadcast command.
The SRS10 Series supports broadcast command.
There is however no response for broadcast command, regardless of whether it is normal or not.
c: Sub-address [f: 1 digit]

The SRS10 Series is a single loop controller and is fixed to 1 (31H).

If other sub-address is used, there is no response due to sub-address error.

(3) Details of basic format portion II

h: Text end character [: 1 digit/ETX (03H)] or [: (3AH)]

Indicates text portion runs up to immediately preceding.

I : BCC data [, : 2 digits]

BCC (Block Check Character) data is for checking if there was an error in the communications data.
In the case of BCC error, the result of BCC operation is no response.
BCC operation includes the following 4 types. (BCC operation types can be set by the front screen.)
(1) ADD
Addition is performed by ASCII data 1 character (1 byte) unit from start character to text end character .
(2) ADD_two's cmp
Addition is performed by ASCII data 1 character (1 byte) unit from start character to text end character
and the 2s complement of the lower 1 byte of operation results is used.
(3) XOR
XOR (Exclusive OR) operation is performed by ASCII data 1 character (1 byte) unit from immediately
following start character (machine address ) to text end character .
(4) None
BCC operation is not performed. ( and omitted)
Operation is performed by 1 byte (8 bits) unit regardless of data bit length (7 or 8).
The lower 1 byte data of the results of the previously described operation are divided into top 4 bits and bottom 4
bits and converted to ASCII data.
: Top 4 bits is data converted to ASCII.
: Bottom 4 bits is data converted to ASCII.

f: No. of data items [l: 1 digit]

Specifies the number read data items of the read command (R) or the number write data items of the write
command (W) and broadcast command (B).
Number of data items is specified by converting binary 4-bit data to ASCII data.
With the read command (R), number of data items is specified within the range of 1 item: 0 (30H) - 10 items: 9 (39H).
With the SRS10 Series, the maximum number of data items that can be read consecutively is 10 items: 9 (39H).
The number of data items for the write command (W) is fixed at 1 item: 0 (30H).
The number of data items for the broadcast command (B) is fixed at 1 item: 0 (30H).
The actual number of data items is No. of data items = specified No. of data items + 1.

6. MODBUS protocol overview

MODBUS protocol includes ASCII and RTU transmission modes.

6-1. Transmission mode overview

(1) ASCII mode
Eight-bit binary data in the command is divided into top and bottom 4 bits and is transmitted as ASCII characters in
hexadecimal notation.

Data configuration
Data format: Selection of 7E1, 7E2, 7N1 or 7N2
Error check: LRC (horizontal redundancy test)
Data communication standard: Max. 1 sec.

(2) RTU mode

Eight-bit binary data in the command is transmitted as is.

Data configuration
Data format: Selection of 8E1, 8E2, 8N1 or 8N2
Error check: CRC-16 (cycle redundancy test)
Data transmission interval: 3.5 character transmission time or less

6-2. Message configuration

6-3. Slave address

Slave addresses are slave machine numbers 1 247. (Up to 255 is possible for SRS10 Series.) Individual slaves are
distinguished by specifying slave address by request message. The master is informed which slave is responding by
setting slave address and returning it for the response message on the slave side.

6-4. Function code

The function code specifies the type of action to the slave.
Function code
03 (03H)
06 (06H)

Details
Slave setting value and information read
Slave write

The function code is also used to show if the response is normal (affirmative response) or what sort of error (negative
response) is occurring when the slave returns a response message to the master.
With affirmative response, the original code is set and returned.
With a negative response, the highest bit of the original function code is set to 1 and returned.
If for instance the function code is mistakenly set to 10H and a request message is sent to the slave, because it is a
nonexistent function code, the highest bit is set to 1 and returned as 90H.
Also for a negative response, in order to inform the master what sort of error has occurred, an abnormal code is set in
the data of the response message and sent.
Abnormal code
1 (01H)
2 (02H)
3 (03H)

Details
Illegal function (nonexistent function)
Illegal data address (nonexistent data address)
Illegal data value (value outside setting range)

19

6-5. Data
Configuration of data differs according to the function code.
With request messages from master machines, it consists of data items, number of data items and set data.
With response messages from slave machines, it consists of number of bytes relative to the request, or abnormal code,
etc., for negative response.
The valid range of data is -32768 to 32767.

6-6. Error check

The error check method differs according to transmission mode.

(1) ASCII mode

Error check in the ASCII mode calculates LRC from slave address to final data item; the 8-bit calculated data is
converted to ASCII character 2 character and set following the data.

LRC calculation method

1. Prepare a message in RTU mode.
2. Add from slave address to final data item and substitute for X.
3. Take the complement of X (bit inverse) and substitute for X.
4. Add 1 to X and substitute for X.
5. Set X as LRC following data.
6. Convert message to ASCII characters.

(2) RTU mode

Error check in the RTU mode calculates CRC-16 from slave address to final data item; the 16-bit calculated data is
set in bottom/top order following the data.

CRC-16 calculation method

CRC formula divides data to be sent by generating polynomial and the remainder is added to the end of the data and sent.
Generating polynomial: X16+ X 15+X 2+1
1. Initialize CRC data (X) (FFFFH)
2. Take the first data item and exclusive OR (XOR) and substitute for X.
3. Shift X 1 bit to the right and substitute for X.
4. If carry is enabled by shifting, take XOR by results X of (3) and fixed value (A001H) and substitute for X.
If carry is enabled, proceed to 5.
5. Repeat steps 3 and 4 until shifted 8 times.
6. Take the next data item and XOR of X and substitute for X.
7. Repeat steps 3-5.
8. Repeat steps 3-5 up to the final data item.
X is set as CRC-16 in message following the data in bottom/top order.

By selecting as the communication address setting, you can operate the machine as the master machine in
various communication protocols.

Note 1: With RS-485 specifications, you should mount the

1/2W 120t terminating resistor that comes with the
terminal element (between + and -) if necessary.
The terminating resistor should however be ultimately
mounted on a single controller only.
Operation cannot be guaranteed if a terminating
resistor is mounted on more than one controller.

Note 1: Only one master within one communications loop. Communication will not be normal if there is more than one master.

7-2. Transmission processing

A write command is sent to write address (slave side communication address) specified in sequence from start slave
address to end slave address.
In reality however the slave side receives write commands only when the communication mode is COM mode, so the
0x018C: communication mode is sent mutually as a command to switch to COM mode. Two commands at a time
are therefore sent to each slave.
The write slave address is always 0 when the start slave address is (broadcast command). Thus data
cannot be written if a machine that does not support broadcast command is connected as a slave.

7-3 Time out

If a response command is not received within 500 msec after transmission to a slave is complete, time out occurs and
data is then transmitted to the next slave machine.

7-4. SV Value Write

If SV values executed such as program control are always changed and if there are multiple slave machines, processing is
not in time for update cycle of SV values, and the SV values may differ among the various slave machines.
If more than one slave machine that supports broadcast command is connected, you can avoid such phenomena by using
the broadcast command.
The SV values sent when the machine is on standby are as follows:
FIX action: SV value of set SV No. is transmitted.
PROG action: Start SV value of start pattern is transmitted.
* For FIX action, the same value is transmitted for both execution and standby.

8. Communication data address

8-1. Communication data address details
Note: The error response code is explained using the code when using Shimaden protocol.

(1) Data address and read/write

Data address is expressed by expressing binary (16-bit) data in hexadecimal notation, 4 bits at a time.
R/W is data that can be read and written.
R is read only data.
W is write only data.
If a write-only data address is specified by read command (R), or if a read-only data address is specified by write
command (W) or broadcast command (B), a data address error results and error response code 0 or 8 (30H,
38H) (text portion format, data address, No. of data items error) is returned.

(2) Data address and No. of data items

If a data address not given in the data addresses for SRS10 is specified as the initial data address, a data address
error results and error response code 0 or 8 (30H, 38H) (text portion format, data address, No. of data items
error) is returned.
For read command, if the front data address is among the given data addresses and the data address to which the
number of data items is added makes it outside the given data addresses, read data is 0.

(3) Data
Because the various data items is binary (16-bit) data without decimal points, the data format, existence of decimal
points, etc., must be checked. (Refer to the SRS10 Series Instruction Manual.)
Example: Expression of data with decimal point
Hexadecimal data
200 00C8
20.0 %
100.00C 10000 2710
-40.00C -4000 F060

The decimal point position is decided by measuring range for data for which the unit is UNIT.
Data is handled as coded binary (16-bit data: -32768 to 32767).
Example: Expression of 16-bit data

(4) Spare of parameter portion

If the Spare portion is read by read command (R) or written by write command (W), normal response code 0, 0
(30H, 30H) is returned.

(5) Parameters concerning optional items

If the data address of a parameter not added as an optional item is specified, abnormal response code 0, C (30H,
43H) (Specification / optional item error) is returned for both the read command (R) and write command (W).

(6) Parameters not displayed on the front panel display due to action or setting specifications
Parameters not displayed (not used) on the front panel display depending on action or setting specifications can be
read and written by communication.
