Executing MSKS(690) in a Cyclic Task
Execute the MSKS(690) instruction from the ladder program in a cyclic task to use interrupt inputs.
MSKS(690) has the following two functions and two of this instruction are normally used in combina-
tion.
(1) Specifying whether to detect ON or OFF signals.
(2) Enabling interrupts.
• Enabling interrupt inputs in Direct Mode
• Enabling the interrupt input counter in Increment or Decrement Counting Mode
Execution condition
The MSKS(690) instruction must be executed only once to make the settings, so in general execute
MSKS(690) in just one cycle using the upwardly differentiated variation of the instruction.
The first MSKS(690) instruction can be omitted. If it is omitted, the edge setting that is set in the PLC
Setup will be used.
