Functionality

The Generic up-down counter function UDFCNT counts up or down for each positive
edge of the corresponding inputs. The counter value output can be reset to zero or
preset to some other value if required.
The function provides up-count and down-count status outputs, which specify the
relation of the counter value to a loaded preset value and to zero respectively.

Operation principle

The function can be enabled and disabled with the Operation setting. The
corresponding parameter values are "On" and "Off".
