3. COMMUNICATION SETTING OF FUNCTION
MODULES
3.1 Address Setting of Function Modules
Only make the module addr ess setting to make the function module (Z-TIO, Z-DIO and Z-CT)
communication setting s.
The SRZ unit performs internal communication (RS-48 5) between the COM-ML- 1 (hereafter called
COM-ML) and the function module (Z-TIO, Z-DIO and Z-CT), so the communication protocol,
communication speed and data bit conf igurati on do not nee d to be set .
A module address is set for each function module type. In this example, the module address is set to
the address shown below.
To avoid problems or malfunction, do not duplicate an address in a function module
of the same type on the same communication line.

3.2 For the SRZ Unit’s Temperature Control Channel
Setting the Z-TIO module address determines the temperature control channel number used for
communication. To each Z-TIO module address, the relevant temperature control channel is
assigned. Each temperatur e control channel number ca n be calcu lated fro m the foll owing eq uation.

4. IP ADDRESS SETTINGS
To use the COM-ML on Ethernet [MODBUS/TCP or PLC communication (MAPMAN) ], IP address
setting is necessary.
The IP address can be set in host communication or loader communication.
4.1 Host Communication Settings
When setting via host c ommunicat ion, refer to the f ollowing R KC commun ication id entifiers and
Modbus register addresses to set the I P address.
The set IP address is enabled by turning OFF the power and then turning it ON again.

3.3 Digital Input/Output Channel of Z-DIO Module
Setting the Z-DIO module add ress determines t he digital input/o utput channel num ber of SRZ unit.
To each Z-DIO module ad dress, the relevant digit al input/output channel is assigned. Each digit al
input/output channel can be calculated from the following equation.

For the IP address, check with the administrator of the network (LAN) to which
the COM-ML is connected.
Our Communication tool “PROTEM 2 ” can be used for the communication setup.
This tool can be downloaded f rom the off icial RK C website :
http://www.rkcinst.com/
For information on connecting the COM-ML to a host computer, refer to COM-ML-1 [For
SRZ] Installation Manual ( IMR02E13 -E).
4.2 Loader Communication Settings
To perform Loader communication, our converter and a communication cable are required.

5. PLC COMMUNICATION ENVIRONMENT
SETTINGS
The PLC communication environmental (system data) settings must be made to perform PLC
communication. The Syste m data settings are made by th e Loader communication (Syst em data
settings can also be made in the Host communication).
The System data contains setting items (ref er to th e Setting item table of below) and monitor items.
The monitor items require sp ace (cor respondi ng to 8 word s) in the PL C registe r.
For the monitor items, re fer to CO M-ML-1 [For SRZ] PLC Commu nica tion Data List
(IMR02E16-E).
5.1 Setting of System Data (setting items)

Set each communication data (PID constants and event set values of the Z-TIO modules and DO
manual outputs of the Z-DIO modules, etc.) using loader communication or host communication.
Host communication or loader com munication is used to con figure the IP address setting,
and thus it is possible to con ti nu e c onf ig uri ng other communication data settin gs af ter t he I P

Host communication settings by loader communication
Communication protocol, c ommunication speed and data bit configuration can be set by loader
communication.
Set switch No.8 to “ON” when perfo rming communication by the communication
settings set via Host communication or Loader communication. When set to “ON,”
the DIP switch settings are disabled.
Set the items in the same way as “4.2 Loader Commun ication Set tings” (same procedures up to
Step 7 of “Setting of PROTEM 2.”
