5. SETTINGS BEFORE OPERATION 5.1 Module Address Setting Set communication setting before mounting and wiring of the Z-TIO module. WARNING 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.
5. SETTINGS BEFORE OPERATION 5.2 Protocol Selections and Communication Speed Setting Use the DIP switch on the right side of module to select communication speed, data bit, configuration and protocol. The data changes become valid when the power is turned on again or when changed to RUN/STOP.

An example of the polling procedure is shown below: Host Host...
Page 61
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.
Page 62
6. RKC COMMUNICATION 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. Refer to 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.
Page 63
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.
Page 64
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.
Host computer sends selecting address for the selecting sequence. Address (2 digits): This data is a module address of the SRZ to be selected and must be the same as the module address set value in item 5.1 Module Address Setting (P. 5-2).
Page 67
<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.
Page 68
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.

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 (SRZ). 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. MODBUS 7.2 Register Read and Write 7.2.1 Read holding registers [03H] 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.
7. MODBUS 7.2.2 Preset single register [06H] The query message specifies data to be written into the designated holding register. The write data is arranged in the query message with high-order 8-bit first and low-order 8-bit next. Only R/W holding registers can be specified.
7. MODBUS 7.2.3 Diagnostics (Loopback test) [08H] The master’s query message will be returned as the response message from the slave. This function checks the communication system between the master and slave. Example: Loopback test for slave address 1 Query message Slave address Function code Test code...
7. MODBUS 7.2.4 Preset multiple registers [10H] The query message specifies the starting register address and quantity of registers to be written. The write data is arranged in the query message with high-order 8-bit first and low-order 8-bit next. Only R/W holding registers can be specified.
7. MODBUS 7.3 Data Processing Precautions The numeric range of data used in Modbus protocol is 0000H to FFFFH. Only the set value within the setting range is effective. FFFFH represents 1. The Modbus protocol does not recognize data with decimal points during communication. Example1: When Heater break alarm (HBA) set value is 20.0 A, 20.0 is processed as 200, 200 = 00C8H...

[The salve set value (Remote SV) is updated at each time lag.] The maximum number of both master and slave Z-TIO modules that can be connected is 16. The SV select function only operates within connected modules (SRZ unit). Remote SV function The Remote SV function controls the Measured value (PV) of the channel specified as the master as a remote SV.
