Execute MSKS Instruction in a Cyclic Task
Execute the MSKS instruction from the ladder program in a cyclic task to use input interrupts.
MSKS has the following two functions and two of this instruction are normally used in combination.
(1)Specifying whether to detect ON or OFF signals.
(2)Enabling input 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.
The first MSKS instruction can be omitted. If it is omitted, an interrupt will be created when the input
turns ON by default.
