The SRZ unit sets all of the data items via communication. Therefore before operation, it is necessary to set value of each data item via communication. The Z-COM module is connected to an SRZ functional module* (hereafter called “functional module”) for the purpose of performing programmable controller communication (hereafter called “PLC communication”) or host communication.

Page 23 2. SETTING PROCEDURE TO OPERATION Setting of PLC communication environment (system data) For PLC communication, set a necessary system data (setting item) via host communication. (Station number, Register type or Register start number, etc.) For MELSEC series, see 7.2.3 PLC communication environment setting (P. 7-11). For SYSMAC series, see 7.3.3 PLC communication environment setting (P.7-25).
Page 24 In addition, writing of the system data (monitor items) begins after the PLC communication start time (factory set value is five seconds) has passed. When collection of the data is completed, the Z-COM module begins writing the communication data of monitor group to the PLC.
Page 25 2. SETTING PROCEDURE TO OPERATION PLC communication initial setting Before changing the SRZ unit data from PLC, always read it into the PLC once. The initial setting must always conduct. If each set value of SRZ unit is changed from the PLC without setting the initial values, it is re-written to 0 with each set value of the PLC at that time set to 0.

This becomes the unit address of the SRZ unit. (The unit address is common to the PLC and host communications.) Set an address for the SRZ unit (address for Z-COM module) using a small blade screwdriver. To avoid problems or malfunction, do not duplicate an address on the same communication line.
Page 38 3. COMMUNICATION SETTING Address setting for PLC communication Up to four Z-COM modules can be connected to a PLC communication port. Therefore the unit address uses the four Z-COM modules as a group. For Z-COM modules which are multi-drop connected to the same PLC communication port, use successive numbers assigned to any one of four groups shown in the following table as their addresses.
Page 39 3. COMMUNICATION SETTING Address setting for host communication (RKC communication or Modbus) Differently from PLC communication, there are no group restrictions. Free settings can be made in the range of 0 to F. For Modbus, the value obtained by adding “1” to the set address corresponds to the address used for the actual program.

3.2.4 Communication setting for loader communication When loader communication is used, the communication speed, communication protocol, and data bit configuration of the Z-COM module are fixed. (There is no need to configure the communication settings of the Z-COM module.) Set the communication settings of the host computer to the same settings as the Z-COM module.
Page 48: Communication Setting Of The Functional Modules
Only make the module address setting to make the functional module (Z-TIO, Z-DIO, etc.) communication settings. The SRZ unit performs internal communication between the Z-COM module and the functional module, so the communication protocol, communication speed, and data bit configuration do not need to be set.

In the PLC communication data map the communication data is classified into system data (monitor items), request command, monitor group, and setting group.
Page 199 7. PLC COMMUNICATION Setting request bit (PLC → SRZ) This command requests that the SRZ unit read the communication data of the setting group on the PLC side. [Processing] 1. When the setting request bit of the request command (D01008) is set to “1,” the SRZ unit starts to read the communication data of the setting group from the PLC.
