Counting Bahavior: Interrupt/ Cancel Counting
You can parameterise the counting behaviour 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.
