High-speed counters
Two mutually independent 32-bit forward and reverse counters are availa-
ble. Each counter has two limit values.
Counter inputs are not electrically isolated.

High-speed counters are programmed in the OM2 organization module.
OM2 also defines which slopes are to be interpreted.
Upon reaching a limit value, a given output assigned in the OM2 automati-
cally goes HIGH.
