CNT
16-bit counter


Operand
C-D C0~C199, D0~D9,999
Explanation

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 matches the setting
value (counter value=setting value), the contact specified will act in the way
described below.
NO (Normally-open) contact OFF
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. Users can reset a counter by means
of the instruction RST.
