Processing details
• This instruction increments the current long counter value (count value) in the device specified by (d) (in SD language or
FBD/LD, displayed as Coil) by one on the rising edge (off to on) of the operation result up to the OUT instruction. When the
count value reaches the set value (current value  set value), the normally open contact turns on (continuity state) and the
normally closed contact turns off (non-continuity state).
• Counting is disabled while the operation result remains on. (Count input does not need to be converted into pulses.)
• After counting-up, the count value and contact status remain unchanged until the RST instruction is executed.
• When the set value is 0, the same processing is performed as when it is set to 1.
