Function description
Limit counter
Functionality
The 12 Up Limit counter (L4UFCNT) provides a settable counter with four
independent limits where the number of positive and/or negative sides 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.
Operation principle
Limit counter (L4UFCNT) counts the number of positive and/or negative sides 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.
