  • Page 49: Counter Mode 1 (Fixed Count, Non-Retentive)

    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, or count down to 0 and stop counting when the current count is equal to 0. Additionally, the current count value is non-retentive and will reset to init value on a powering up to the LRD.
  • Page 50: Counter Mode 2 (Continuous Count, Non-Retentive)

    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.
  • Page 51: Counter Mode 3 (Fixed Count, Retentive)

    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, the current value will not be init value when Counter powers up, but be the value when it is 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 is configured as down counter.
  • Page 52: Counter Mode 5 (Continuous Count, Up-Down Count, Non-Retentive)

    COUNTER MODE 5 (CONTINUOUS COUNT, UP-DOWN COUNT, NON-RETENTIVE) Mode 5 Counter operation is similar to Mode 2 except its current count value is continuous and non-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.
  • Page 53: Counter Mode 6 (Continuous Count, Up-Down Count, Retentive)

    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.
