Attention:
As the start/reset element is configured here as a logic reset and connected as an element to a flip-flop
element, the flip-flop is reset at high signal...
The status of the monitoring functions is formed again after a reset:
• If the limits configured are exceeded, process values do not cause the output status of
the monitoring function to change
• Time-based functions - timers reset the output status of the monitoring function.
Triggering only occurs if the limits configured are exceeded again
Process value (position) => no change to the output status on reset in the alarm state
