1)Counter enable
2)Transfer preset actual value on rising edge
3)Count direction: 0 = up counting, 1 = down counting
4)Reset actual value to zero
5)Zero: Status 1 if the value of the function block output QV (the counter status) equals zero
6)Carry: Status 1 if the value range is exceeded
7) | Fall below: Status 1 if the actual value | lower setpoint |
8) | Overflow: Status 1 if the actual value | lower setpoint |
