COUNTER MODE 2 (CONTINUOUS COUNT, NON-RETENTIVE)
Mode 2 Counter will count up to a fixed preset value and continue counting after the preset value, but it will not count when the current value
equals 0 if it is configured as down Counter. Additionally, the current count value is non-retentive and will reset to init value on a powering up to
the LRD or switching between RUN and STOP. In the example below, the counter will continue counting after its preset value of 20. Counter
status bit C01 will be ON when the current value is 20.
– Under this mode, Counter will continue counting after reaching preset value if it is configured as counter up. But it stops counting when its
current value is 0 if it is configured as counter down.
– The counter current value will be init value when the LRD status switches between RUN and STOP or the LRD is powered up. If the counter is
configured as counting up, the init value is 0 or else, it is the preset value.
