14.10.2 Functionality
GUID-13157EAB-1686-4D2E-85DF-EC89768F3572 v6
The Limit counter (L4UFCNT) provides a settable counter with four independent
limits where the number of positive and/or negative flanks on the input signal are
counted against the setting values for limits. The output for each limit is activated
when the counted value reaches that limit.
Overflow indication is included for each up-counter.
14.10.3 Operation principle
GUID-4D58423F-329C-4553-9FAF-E55A368849A5 v2
Limit counter (L4UFCNT) counts the number of positive and/or negative flanks on
the binary input signal depending on the function settings. L4UFCNT also checks
if the accumulated value is equal or greater than any of its four settable limits. The
four limit outputs will be activated relatively on reach of each limit and remain
activated until the reset of the function. Moreover, the content of L4UFCNT is
stored in flash memory and will not be lost at an auxiliary power interruption.
