Periodic counting
No primary counting direction
– Counting starting at the load value, up or down.
– Upon reaching the corresponding count limit, the counter
jumps to the load value and starts counting again from
there. In addition, a process alarm can be triggered if it is
parametrized.
– Because of the register size, the count limits are xed and
cannot be changed.

Primary counting direction up
– Up-counting starting at the load value
– If the end value -1 is reached during counting in the posi-
tive direction, the counter jumps to the load value at the
next positive count pulse and continues counting from
there. In addition, a process alarm can be triggered if it is
parametrized.
– It is possible to count beyond the lower count limit.

– Down-counting from the load value
– If the end value +1 is reached during counting in the neg-
ative direction, the counter jumps to the load value at the
next count pulse and continues counting from there. In
addition, a process alarm can be triggered if it is parame-
trized.
