(d) I/O refresh setting
The CPU module updates all inputs and outputs of the input/output modules and intelligent function modules by
I/O refresh. ( Section 3.8.1)
I/O refresh setting allows I/O refresh to be performed for each program (within the specified range).
1) Application
This setting is useful when fixed scan execution type programs are used. The CPU module takes in inputs (X)
before execution of each fixed scan execution type program and externally outputs the operation results
(outputs (Y).
Scan time of the program being executed (except for fixed scan execution type programs) can be checked on the Program
monitor list screen. ( Section 6.13.1)
