z
Execute MSKS in a Cyclic Task
The MSKS instruction must be executed from the ladder program in a cyclic task in order to use
scheduled interrupts.
The MSKS instruction must be executed only once to make the settings, so in general execute
MSKS in just one cycle using the upwardly differentiated variation of the instruction.
10-3-2 Flow of Operation
Write the program for the corresponding interrupt task 1 (fixed).
Use MSKS to specify the scheduled interrupt interval.
The setting can be 1 ms or longer.
Set N to 4 or 14 in the MSKS instruction.
