No main counting direction
• The counter counts once starting with the load value.
• You may count forward or backwards.
• The count limits are set to the maximum count range.
• At over- or underrun at the count limits, the counter jumps to the
according other count limit and the gate is automatically closed.
• To restart the count process, you must create an edge 0-1 of the gate.
• At interrupting gate control, the count process continuous with the last
recent counter value.
• At aborting gate control, the counter starts with the load value.
