1. HANDLING PROCEDURES
Communication setting Refer to 2. COMMUNICATION SETTING
• Refer to COM-JC [For SRZ] Installation Manual
Mounting and Wiring
(IMR01Y22-E )
• For SRZ, refer to Z-TIO Instruction Manual (IMS01T01-E )
and Z-DIO Instruction Manual (IMS01T03-E ).
PLC setting
Refer to 4.2 Setting the Instruments Used
• Refer to 4.2 Setting the Instruments Used
Controller setting
• Refer to Z-TIO Host Communication Quick
Instruction Manual (IMS01T02-E ) and Z-DIO
Instruction Manual (IMS01T03-E ).
Device assignment
Refer to 4.3 Device Assignment Example
Program creation
Refer to 4.4 Sample Program
To avoid error at operation start-up, COM-JC must be powered on LAST
(after the Controller, PLC, etc.).
2. COMMUNICATION SETTING
CAUTION
Do not separate the mainframe from the terminal base with the power turned
on. If so, instrument failure may result.
2.1 Station Number Setting
Set the station number of CC-Link using a small blade screwdriver.

3. CC-Link FLAG OPERATION
Remote input/output and remote register flag operations are as follows.
[Example] When the occupied station/extended cyclic of COM-JC is set to 4 stations
occupied 1 time.
Initialize request processing at power on
Initialize processing request from remote device station (COM-JC)
If the COM-JC is initialized at power on, the initialize data processing request flag [RX(n+7)8]
is turned on. Thus, turn on the initialize data processing completion flag [RY(n+7)8].
When COM-JC becomes a ready state, a remote ready [RX(n+7)B] is turned on.

Extension number for display selection processing
After the extension number for display [RYn0 to RYn5, RY(n+1)0 to RY(n+1)2] is set, turn
on the extended display flag [RYnC]. After the data in the remote register [RWrn to
RWrn+F] is displayed, check that extended display completion [RXnC] is turned on and
then turn off the extended display flag [RYnC]. If the extended display flag is turned off, the
extended display completion is turned off.

on the extended setting flag [RYnD]. After the content of the remote register [RWwm to
RWwm+F] is set, check that extended setting completion [RXnD] is turned on and then
turn off the extended setting flag [RYnD]. If the extended setting flag [RYnD] is turned off,
(1 channel assignment)
the extended setting completion [RXnD] is turned off.
