Thank you for purchasing this RKC product. In order to achieve maximum performance
and ensure proper operation of your new instrument, carefully read all the instructions in
this manual. Please place this manual in a convenient location for easy reference.
1. OUTLINE
Using the setting examples below, this section explains the configuration when two Z-TIO-C
or Z-TIO-D temperature control modules (supporting PLC communication) are connected to
a MITSUBISHI MELSEC Series programmable controller (PLC).
The PLC communication environmental settings are required to communicate with the PLC.
The PLC communication environmental settings are set by the host communication or
loader communication, so the host computer and Z-TIO-C or Z-TIO-D module must be
connected. (This manual is the explanation by the loader communication.)

3. COMMUNICATION SETTING OF Z-TIO MODULE
Set communication setting before mounting and wiring of the Z-TIO module.
Do not separate the module mainframe from the base with the power turned on. If
so, instrument failure may result.
3.1 Module Address Setting
Set an address for the Z-TIO-C or Z-TIO-D module using a small blade screwdriver.
• When one module is used, set the module address to 0.
• When multiple modules are used, be sure to set one of the modules to module address 0.
The module with module address 0 will be the master module.

• To avoid problems or malfunction, do not duplicate an address on the
same communication line.
• For Modbus, the value obtained by adding “1” to the set address
corresponds to the address used for the actual program.
3.2 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.

(The above figure is for the terminal type. However, the switch positions are the same for the connector type.)
• Switch No. 8 must be always OFF. Do not set to ON.
• When two or more Z-TIO-C or Z-TIO-D modules are connected on the same
communication line, the DIP switch settings of all modules must be the
same.
For communication settings when connected to a different functional module, see
the SRZ Instruction Manual [For PLC communication] (IMS01T13-E ).
Set the DIP switch settings to the same values as the connected PLC.

Connect a termination resistor between the communication terminals (No.3
and No. 4) of the module at the end of the communication line from the host
computer or PLC.
The communication cable must be provided by the customer.
Terminal configuration and wiring example
The Z-TIO-C/D module has RS-485 communication terminals for RKC communication,

6. PLC COMMUNICATION ENVIRONMENT
SETTING VIA LOADER COMMUNICATION
This section explains how to configure the PLC communication environment settings by
loader communication.
To perform loader communication, a communication program must
be created.
6.1 Preparation of USB Communication Converter
To perform loader communication, our converter and a communication cable are required.
USB communication converter COM-K (With USB cable)
Loader communication cable W-BV-01 [option]
6.2 Preparation of Communication Program
Refer to the RKC communication protocol or the Modbus communication protocol to create
a communication program.
(However, the loader communication cannot be used when Modbus protocol is selected.)
For RKC communication or Modbus communication protocol, see SRZ Instruction
Manual (IMS01T04-E ).
6.3 Setting of Loader Communication
For loader communication, set the communication port of the computer to the following
values. There are no loader communication settings on the Z-TIO-C/D module side.
