Chapter 4 Relay Ladder Logic Programming 50
Counter Mode 1 (Fixed Count, Non-Retentive)
Mode 1 Counter will count up to a fixed preset value and stop counting when the current count is equal to the
preset value. Additionally, the current count value is non-retentive and will reset to zero on a loss of power to the
smart relay. In the example below, the counter will stop counting when it reaches the preset value of 20. Counter
status bit C1 will be ON when the current value is 20.
