
When the counter coil specified by the instruction CNT is turned from
OFF to ON, the counter value increases by 1. If the counter value

NC (Normally-closed) contact ON

If there are pulses sent to the counter specified by the instruction CNT
after the counter value matches the setting value, the state of the
contact specified and the counter value will remain unchanged.
