Counting Behavior: Cancel/Interrupt Counting
You can parameterize the counting behavior after a new gate start: Using
Interrupt counting
, the
counter continues from the last counting value. Using
Cancel counting
, counting starts again from
the load value.
Endless Counting
Continous Counting
•
Counting starts at the load value, the entire counting range is used.
•
If the upper count limit is reached during up-counting, an additional counting pulse in the
positive direction leads to a jump to the lower count limit. Counting continues from there.
•
If the lower count limit is reached during down-counting, an additional counting pulse in the
negative direction leads to a jump to the upper count limit. Counting continues from there.
•
Upon exceeding the upper or lower counting limit, the status bit
Overflow performed
or
Underflow performed
is set and a process alarm is triggered if it is parameterized. The status
bits remain set until they are reset with the bit “Reset status bits” in the control word.
