COUNTER MODE 6 (CONTINUOUS COUNT, UP-DOWN COUNT, RETENTIVE)
Mode 6 Counter operation is similar to Mode 4 except its current count value is continuous and retentive. The status bit is fixed to the non-zero
preset value regardless of the state of the direction bit. Its status bit will be ON when the counter current value is not less than its preset value,
and will be OFF when the current value is less than its preset value. Additionally, the Mode 6 counter is always reset to zero, unrelated to the
state of its direction bit. The current count value is retentive and will keep its current count after a loss of power to the LRD relay. Counter will
keep current value if “C Keep” is active. 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 not less than 20.
This mode is similar to mode 5, but:
– The current value is kept at loss of power down to the LRD when it status is RUN.
– The current value is kept when the LRD switches between RUN and STOP if “C Keep” is active.
