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.
CAUTION
IMS01T11-E2
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.

Setting range: 0 to F [0 to 15: Decimal]
Factory set value: 0

• 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.

frame
(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.

!
DIP switch
To prevent electric shock or instrument failure, turn off the
power before connecting or disconnecting the instrument and
peripheral equipment.
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.
OFF ON
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,
Modbus/RTU communication and PLC communication protocol. Communication terminals
are on the base side.
