Operation principle

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.
The counter value is stored in flash memory once per hour and will not be lost at auxiliary power
interruption.
