This chapter describes features, package contents and model code, etc. The module type controller has the
following features:
Module type controller SRZ interfaces with the host computer via Modbus or RKC communication
protocols. The SRZ sets all of the data items via communication (The communication interface used for
both protocols is RS-485.). Therefore before operation, it is necessary to set value of each data item via
communication.
Common to both Z-TIO and Z-DIO module
• A user can select RKC communication or Modbus.
• When each module is connected, the power and communication lines are connected internally within the
modules, and thus it is only necessary to wire one module to the power terminal and communication
terminal; there is no need to individually wire each module to the terminals. This reduces the amount of
wiring needed.
• Compact size
Terminal type: depth 85 mm, Connector type: depth 79 mm
Z-TIO module
• The Z-TIO module is a temperature control module equipped with either two or four control channels.
• The measurement input is a universal input that supports thermocouple input, resistance temperature sensor
input, voltage input, current input, and feedback resistance input.
• The input type can be specified separately for each channel, and different input types can be combined.
• Output types are relay contact output, voltage pulse output, voltage output, current output, open collector output, and
triac output. Output types are specified when the order is placed, and a different output type can be specified for
each channel.
• 4CH Z-TIO module can have 4 CT (current transformer) inputs.
• Up to 16 Z-TIO modules can be connected.
[The maximum number of SRZ modules (including other function modules) on the same communication line is 31.]
Z-DIO module
• The Z-DIO module is an event input/output module equipped with digital inputs and outputs (DI8 points
/ DO8 points).
• DI signal assignment enables switching of various mode states and memory areas of the Z-TIO module.
• DO signal assignment enables output of the event result of the Z-TIO module to the event output (DO),
and output of the DO manual output state of the Z-DIO module.
• Up to 16 Z-DIO modules can be connected.
[The maximum number of SRZ modules (including other function modules) on the same communication line is 31.]
For reference purposes, the Modbus protocol identifies the host computer as master, each module
of SRZ as slave.

4. WIRING
4.1 Wiring Cautions
This chapter describes wiring cautions, wiring layout and wiring of terminals.
To prevent electric shock or instrument failure, do not turn on the power until all
the wiring is completed.
• For thermocouple input, use the appropriate compensation wire.
• For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires
(3-wire system).
• To avoid noise induction, keep input/output signal wires away from instrument power line, load lines and
power lines of other electric equipment.
• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.
− Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise
reduction.
− Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise
filter output and the instrument power supply terminals to achieve the most effective noise reduction.
− Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness
of the noise filter.
• About eight seconds are required as preparation time for contact output every time the instrument is
turned on. Use a delay relay when the output line is used for an external interlock circuit.
• Power supply wiring must be twisted and have a low voltage drop.
• For an instrument with 24 V power supply, supply power from a SELV circuit.
• A suitable power supply should be considered in the end-use equipment. The power supply must be in
compliance with a limited-energy circuits (maximum available current of 8 A).
• Supply the power to only one of the joined modules. When power is supplied to any one of the joined
modules, all of the joined modules will receive power.
• Select the power capacity which is appropriate for the total power consumption of all joined modules and
the initial current surge when the power is turned on.
Power consumption (at maximum load): 140 mA max. (at 24 V DC) [Z-TIO module (4CH type)]
80 mA max. (at 24 V DC) [Z-TIO module (2CH type)]
70 mA max. (at 24 V DC) [Z-DIO module]
Rush current: 10 A or less

4.2 Connecting Precautions
To prevent electric shock or instrument failure, turn off the power before
connecting or disconnecting the instrument and peripheral equipment.
• Connect connectors correctly in the right position. If it is forcibly pushed in with pins in the wrong
positions, the pins may be bent resulting in instrument failure.
• When connecting or disconnecting the connectors, do not force it too far to right and left or up and down,
but move it on the straight. Otherwise, the connector pins may be bent, causing instrument failure.
• When disconnecting a connector, hold it by the connector itself. Disconnecting connectors by yanking on
their cables can cause breakdowns.
WARNING
!
• To prevent malfunction, never touch the contact section of a connector with bare hands or with hands
soiled with oil or the like.
• To prevent damage to cables, do not bend cables over with excessive force.

5. SETTINGS BEFORE OPERATION
5.1 Module Address Setting
Set communication setting before mounting and wiring of the Z-TIO.
To prevent electric shock or instrument failure, always turn off the power
before setting the switch.
To prevent electric shock or instrument failure, never touch any section other
than those instructed in this manual.
CAUTION
WARNING
!
Do not separate the module mainframe from the base with the power turned on. If so,
instrument failure may result.
Address setting switches
Set an address for the module using a small blade screwdriver.
When using two or more modules, set the desired address to each module.
To avoid problems or malfunction, do not duplicate an address on the same communication
line.
Module address number of each module:
Z-TIO module

5.3 Operating Precautions
Check the following items before starting operation, then turn on the power.
Power ON
When first powered on, the unit starts with the operation mode set to "Control" and the RUN/STOP switch
set to STOP (control is stopped) (FAIL/RUN display lamp: lights green).
When the RUN/STOP switch is switched from STOP to RUN, operation begins. [Factory set value: STOP]
Action at input error
If the input signal wiring is disconnected or short-circuited (RTD input and Feedback resistance input only),
the instrument determines that burnout has occurred.

Checking the each parameter
The settings for the SV and all parameters should be appropriate for the controlled system.
There are parameters in Engineering setting which can not be changed when the controller is in RUN mode.
Change the RUN/STOP mode from RUN to STOP when a change for the parameters in Engineering setting
is necessary.
For details of the each parameter, see 8. COMMUNICATION DATA DESCRIPTION (P. 8-1).
Operation when power failure
A power failure of 4 ms or less will not affect the control action. When a power failure of more than 4 ms
occurs the instrument assumes that the power has been turned off. When the power returns, the operation of
instrument will be re-starts in accordance with the content selected by Hot/Cold start.
For details of Hot/Cold start, see Hot/Cold start (P. 8-92).
Event hold action
• The event action is activated when the power is turned on or when transferred from STOP mode to RUN
mode.
• The event re-hold action is activated when not only the SV is changed, but also the power is turned on or
when transferred from STOP mode to RUN mode.

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.

6.1 Polling
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 SRZ).
• 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 SRZ:
EOT (04H), ENQ (05H), ACK (06H), NAK (15H), STX (02H), ETB (17H), ETX (03H)
( ): Hexadecimal
6.1.1 Polling procedures
Polling is the action where the host computer requests one of the connected SRZ to transmit data.
An example of the polling procedure is shown below:

(1) Data link initialization
Host computer sends EOT to the controllers to initiate data link before polling sequence.
(2) Data sent from host computer - Polling sequence
The host computer sends the polling sequence in the following two types of formats:
• Format in which no memory area number is specified, and
• Format in which the memory area number is specified.
• When no memory area number is specified
To be sent in this format for any identifier not corresponding to the memory area.

Identifier Address
1. Address (2 digits)
This data is a module address of the SRZ for polled and must be the same as the module address
set value in item 5.1 Module Address Setting (P. 5-2).
The polling address which transmitted a message once becomes effective so long as data link
is not initialized by transmit and receive of EOT.
2. Memory area number (2 digits)
This is the identifier to specify the memory area number. It is expressed by “K1” to “K8” to each
memory area number (from 1 to 8). If the memory area number is assigned with “K0,” this represents
that control area is specified.
The memory area now used for control is called “Control area.”
If the memory area number is not specified when polling the identifier corresponding to the
memory area, this represents that the control area is specified.
If any identifier not corresponding to the memory area is assigned with a memory area
number, this memory area number is ignored.

3. Identifier (2 digits)
The identifier specifies the type of data that is requested from the SRZ. Always attach the ENQ code
to the end of the identifier.
See 6.4 Communication Data List (P. 6-13).
4. 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 SRZ.
(3) Data sent from the SRZ
If the polling sequence is received correctly, the SRZ sends data in the following format:
Identifier DataBCCETBSTX
Identifier DataBCCETXSTX
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 6.4 Communication Data List (P. 6-13).
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.

• When data range is 0 hour 00 minute to 99 hours 59 minutes:
Data range is 0:00 to 99:59, punctuation of time unit is expressed in colon “: (3AH).”
• When data range is 0 minute 00 second to 199 minutes 59 seconds:
Data range is 0:00 to 199:59, punctuation of time unit is expressed in colon “: (3AH).”
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.
(4) EOT send (Ending data transmission from the SRZ)
In the following cases, the SRZ 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 SRZ
The SRZ 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.
IMS01T04-E1

6. RKC COMMUNICATION
(6) ACK (Acknowledgment)
An acknowledgment ACK is sent by the host computer when data received is correct. When the SRZ
receives ACK from the host computer, the SRZ will send any remaining data of the next identifier without
additional action from the host computer.
• When ACK was sent in succession for Z-TIO module, identifier data item down to “Communication
switch for logic” in the communication identifier list are sent.
• When ACK was sent in succession for Z-DIO module, identifier data item down to “DO minimum
ON/OFF time of proportioning cycle” in the communication identifier list are sent.
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 SRZ, it sends a negative acknowledgment NAK
to the SRZ. The SRZ 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 SRZ sends data, the
SRZ sends EOT to terminate the data link (time-out time: about 3 seconds).
(9) Indefinite response from host computer
The SRZ 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 SRZ or to
terminate the data link due lack of response from the SRZ.

For the STX, Memory area number Identifier, Data, ETB, ETX and BCC,
see 6.1 Polling (P. 6-2).
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.
Area soak time set data as the following:
• When data range is 0 hour 00 minute to 99 hours 59 minutes:
Data range is 0:00 to 99:59, punctuation of time unit is expressed in colon “: (3AH).”
• When data range is 0 minute 00 second to 199 minutes 59 seconds:
Data range is 0:00 to 199.59, punctuation of time unit is expressed in colon “: (3AH).”
In addition to above, when minute and second data are set in more than 60, become as the
following:
• Data with numbers below the decimal point omitted or zero-suppressed data can be received.
(Number of digits: Within 7 digits)
<Example> When data send with −001.5, −01.5, −1.5, −1.50, −1.500 at the time of −1.5, SRZ can
receive a data.
• When the host computer sends data with decimal point to item of without decimal point, the SRZ
receives a message with the value that cut off below the decimal point.
<Example> When setting range is 0 to 200, the SRZ receives as a following.

(4) ACK (Acknowledgment)
An acknowledgment ACK is sent by the SRZ when data received is correct. When the host computer
receives ACK from the SRZ, the host computer will send any remaining data. If there is no more data to be
sent to the SRZ, the host computer sends EOT to terminate the data link.
(5) NAK (Negative acknowledge)
If the SRZ 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 SRZ 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
• When receive data is the identifier of RO (read only)
(6) No response from SRZ
The SRZ 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 SRZ.

7.1 Communication Protocol
The master controls communication between master and slave. A typical message consists of a request
(query message) sent from the master followed by an answer (response message) from the slave. When
master begins data transmission, a set of data is sent to the slave in a fixed sequence. When it is received,
the slave decodes it, takes the necessary action, and returns data to the master.
7.1.1 Message format
The message consists of four parts: slave address, function code,
data, and error check code which are always transmitted in the
same sequence.
Slave address
Function code
Data
Error check CRC-16
Message format
Slave address
The slave address is a number from 0 to F manually set at the module address setting switch located at the
front of the function module (Z-TIO, Z-DIO).
For details, see 5.1 Module Address Setting (P. 5-2).
Although all connected slave units receive the query message sent from the master, only the slave with the
slave address coinciding with the query message will accept the message.
Function code
The function codes are the instructions set at the master and sent to the slave describing the action to be
executed. The function codes are included when the slave responds to the master.
For details, see 7.1.2 Function code (P. 7-3).
Data
The data to execute the function specified by the function code is sent to the slave and corresponding data
returned to the master from the slave.
For details, see 7.2 Message Format (P. 7-8), 7.3 Data Configuration (P. 7-12) and
7.5 Communication Data List (P. 7-22).
Error check
An error checking code (CRC-16: Cyclic Redundancy Check) is used to detect an error in the signal
transmission.
For details, see 7.1.5 Calculating CRC-16 (P. 7-5).

Error check CRC-16 (Cyclic Redundancy Check)
* When sending a command message from the master, set intervals of data configuring one message to time shorter than the 24 bits’
time. If time intervals become time longer than the 24 bits’ time the relevant slave assumes that message sending from the master
is terminated to deform the message format. As a result, the slave does not make a response.

7.1.4 Slave responses
(1) Normal response
• In the response message of the Read Holding Registers, the slave returns the read out data and the
number of data items with the same slave address and function code as the query message.
• In the response message of the Preset Single Register, the slave returns the same message as the query
message.
• In the response message of the Diagnostics (Loopback test), the slave returns the same message as the
query message.
• In the response message of the Preset Multiple Registers, the slave returns the slave address, the function
code, starting number, and number of holding registers in the multi-query message.
(2) Defective message response
• If the query message from the master is defective, except for
transmission error, the slave returns the error response message without
any action.
• If the self-diagnostic function of the slave detects an error, the slave
will return an error response message to all query messages.
• The function code of each error response message is obtained by adding
Slave address

Error code Contents
1 Function code error (An unsupported function code was specified)
2 When the mismatched address is specified.
3 When the specified number of data items in the query message exceeds the
maximum number of data items available
4 Self-diagnostic error response
(3) No response
The slave ignores the query message and does not respond when:
• The slave address in the query message does not coincide with any slave address settings.
• The CRC code of the master does not coincide with that of the slave.
• Transmission error such as overrun, framing, parity and etc., is found in the query message.
• Data time interval in the query message from the master exceeds 24 bit’s time.

7.1.5 Calculating CRC-16
The Cyclic Redundancy Check (CRC) is a 2 byte (16-bit) error check code. After constructing the data
message, not including start, stop, or parity bit, the master calculates a CRC code and appends this to the
end of the message. The slave will calculate a CRC code from the received message, and compare it with
the CRC code from the master. If they do not coincide, a communication error has occurred and the slave
does not respond.
The CRC code is formed in the following sequence:
1. Load a 16-bit CRC register with FFFFH.
2. Exclusive OR (⊕) the first byte (8 bits) of the message with the CRC register. Return the result to the
CRC register.
3. Shift the CRC register 1 bit to the right.
4. If the carry flag is 1, exclusive OR the CRC register with A001 hexadecimal and return the result to
the CRC register. If the carry flag is 0, repeat step 3.
5. Repeat step 3 and 4 until there have been 8 shifts.
6. Exclusive OR the next byte (8 bits) of the message with the CRC register.
7. Repeat step 3 through 6 for all bytes of the message (except the CRC).
8. The CRC register contains the 2 byte CRC error code. When they are appended to the message, the
low-order byte is appended first, followed by the high-order byte.

Example of a CRC calculation in the ‘C’ language
This routine assumes that the data types ‘uint16’ and ‘uint8’ exists. Theses are unsigned 16-bit integer
(usually an ‘unsigned short int’ for most compiler types) and unsigned 8-bit integer (unsigned char). ‘z_p’
is a pointer to a Modbus message, and ‘z_messaage_length’ is its length, excluding the CRC. Note that the
Modbus message will probably contain NULL characters and so normal C string handling techniques will
not work.
/* CRC runs cyclic Redundancy Check Algorithm on input z_p */
/* Returns value of 16 bit CRC after completion and */
/* always adds 2 crc bytes to message */
/* returns 0 if incoming message has correct CRC */
The query message specifies the starting register address and quantity of registers to be read.
The contents of the holding registers are entered in the response message as data, divided into two parts: the
high-order 8-bit and the low-order 8-bit, arranged in the order of the register numbers.
Example: The contents of the four holding registers from 0000H to 0003H are the read out from slave
address 2.
