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.
