7.4 I/O Port Nos. and Corresponding PLC Addresses
In PLC, ASEL, PSEL or SSEL CC-Link board is set as the remote device station. The number of occupied remote
device stations varies, depending on the I/O point setting on the ASEL, PSEL and SSEL side.
The following table shows the example when I/O parameter No. 1 is set to “0”, No. 16 to “0” and No. 17 to “300” in
the program mode. This shows the relationship between the I/O port Nos. decided by means of the setting of I/O
parameter No 14 and No. 15, and the PLC addresses. The last one word for the occupied remote I/O shows the
system domain for the remote device station, so the corresponding ports can not be used as the I/O ports.
Note: Take whichever is the larger of the point values for I/O Parameter No. 14 and No. 15 and set that same value for both for
No. 14 and No. 15.

In the case that the I/O Point Setting is up to 96 points:
They are configured as a single remote device (No. of Occupied Stations: One Station)
