Setting unused I/O slots to empty (0 points) (only when connecting to QCPU (Q
mode))
Setting unused I/O slots as empty slots (0 points) from "PC parameters" "I/O
assignments" of GX Developer allows you to use I/O numbers of "16 points x
number of empty slots" for other purposes.
For details on I/O assignment settings, refer to the following manual:
QCPU User's Manual (Function Explanation, Program Fundamentals)
Example: I/O assignment (when 16 points are assigned to each of all modules
