Additionally, the current count value is non-retentive and will reset to init value on a powering up to the smart relay.
Page 66 Chapter 4 Relay Ladder Logic Programming 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 won’t count when the current value equals 0 if it’s configured as down Counter. Additionally, the current count value is non-retentive and will reset to init value on a powering up to the smart relay or switching between RUN and STOP.
Page 67 Chapter 4 Relay Ladder Logic Programming Counter Mode 3 (Fixed Count, Retentive) Mode 3 Counter operation is similar to Mode 1 except its current count value is retentive when Counter powers down. So, current value won’t be init value when Counter powers up, but be the value when it powering down. Mode 3 Counter will count up to a fixed preset value and stop counting at that value, or stop counting when its current value is 0 if it’s configured as down counter.
