Counter (CNT)
The Counter is a two-input counter that increments
when the count input logic transitions from off to on.
When the counter reset input is on the counter resets
to 0. When the current value equals the preset value,
the counter status bit comes on and the counter
continues to count up to a maximum count of 9999.
The maximum value will be held until the counter is
reset.
Instruction Specifications
Counter Reference (CTaaa): Specifies the counter number.
Preset Value (Bbbb): Constant value (K) or a V-memory location. (Pointer (P) for DL240,
DL250-1 and DL260.)
Current Values: Counter current values are accessed by referencing the associated V or CT
memory locations. The V-memory location is the counter location + 1000. For example, the
counter current value for CT3 resides in V-memory location V1003.
Discrete Status Bit: The discrete status bit is accessed by referencing the associated CT
memory location. It will be on if the value is equal to or greater than the preset value. For
example the discrete status bit for Counter 2 would be CT2.
NOTE: A V-memory preset is required only if the ladder program or an OIT must used to change the preset.
NOTE: * Both the Counter discrete status bits and the current value are accessed with the same data
reference with the HPP. DirectSOFT uses separate references, such as “CT2” for discrete status bit for
Counter CT2, and “CTA2” for the current value of Counter CT2.
