CC-Link Communication Converter
IMR01Y26-E2
In order to achieve maximum performance and ensure proper operation of your new
instrument, carefully read all the instructions in the manual. Please place this manual
in a convenient location for easy reference.
This manual describes the basic operation only.
1. HANDLING PROCEDURES
To avoid error at operation start-up, COM-JC must be powered on LAST
(after the Controller, PLC, etc.).
2. COMMUNICATION SETTING
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.
Setting range:
1 to 61 ( 4 stations occupied 1 time,
4 stations occupied 2 times,
4 stations occupied 4 times)
1 to 64 (1 station occupied 1 time)
Factory set value: 0

2.2 Communication Speed Setting
Set the communication speed 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
z
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.

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.

turn off the extended setting flag [RYnD]. If the extended setting flag [RYnD] is turned off,
the extended setting completion [RXnD] is turned off.
