I/O Signals to/from CPU Module

This section describes I/O signals of the QJ61CL12 for the CPU module.
Input signals (X) are assigned to the remote input area, and output signals (Y) are assigned to the remote output area.
No special I/O signal is required to operate the QJ61CL12.
I/O assignments vary depending on the point mode setting.
In the tables in Page 29, Section 3.2.1 to Page 30, Section 3.2.3, "n" indicates the start I/O number of the QJ61CL12.
Ex.
● If the number of occupied I/O points is set larger than the maximum number of link points in the 4-point mode or 8-point
● If remote station numbers are duplicated, the duplicating stations may cause malfunction (incorrect input/output).
● A remote station may occupy multiple station numbers depending on the point mode setting and the number of I/O points

mode, the excessive I/O points cannot be used.
When the point mode is in the 4-point mode and the number of occupied I/O points is set to 1024
Ex.
According to the setting, the QJ61CL12 can occupy 1024 I/O points in the CPU module.
However, the number of actual link points is 256 (the maximum link points when the 4-point mode is set).
The rest of I/O points (768) cannot be used.
Check that the remote station numbers are not duplicated before powering on the system.
of the remote station.
When using a remote station having the number of I/O points of eight or more, check that the station number of the
remote station is not duplicated with that of the next station.
