Canceling- and Interrupting-Type Gate Function
When assigning the gate function, you can specify whether the internal gate is to cancel or
interrupt counting. When counting is canceled, after the gate is closed and restarted,
counting starts again from the beginning. When counting is interrupted, after the gate is
closed and restarted, counting continues from the previous value.
The diagrams below indicate how the interrupting and canceling gate functions work:
