Users can set the time it takes for the input terminals to respond by
setting SR020. The value in SR020 must be in the range of 0 to 20. (Unit:
ms)
If the module is turned form OFF to ON, the value in SR020 will
automatically become 10, and the value in SR021 will automatically
become 10.

If the program below is executed, the time is takes for the input terminal to
respond will be 0 milliseconds. Owing to the fact that the input terminals
are connected to resistor–capacitor circuits in series, the shortest time it
takes for the input terminals to respond is 50 microseconds.

If high-spedd counters and interrupts are used in a program, the value in
SR020 does not have any effect.
If SM039 is ON, the time it takes for the program to be scanned will
depend on the value in SR039. If the execution of a program is complete,
the program will not be scanned again until the fixed scan time set
elapses. If the value in SR039 is less than the time it takes for a program
to be scanned, the time it takes for a program to be scanned, will be given
priority.
