Counter Function Block Diagram
The counter function block counts the input pulses at an input and
turns on the Output Enable signal when the count reaches a preset
value. You set this value using RSNetWorx for DeviceNet software.
When the input count reaches the preset value, the Output Enable
signal turns on and is held on. To detect pulses in the input signal, the
input pulse’s off-time and on-time must be longer than the controller’s
cycle time. If the input pulse signal off-time and on-time are shorter
than the controller’s cycle time, pulses may be missed.
