Limit counter L4UFCNT
GUID-7EBDC372-3407-4577-8B9A-6AB1758A1F34 v2
The Limit counter function L4UFCNT can be tested by connecting a binary input
to the counter and applying pulses to the counter. The speed of the pulses must not
exceed the cycle time of the function. Normally the counter will be tested when
testing the function that the counter is connected to, such as the trip function. When
the function is configured, test it together with the function that operates it. Trigger
the function and check that the counter result corresponds to the number of
operations.
