Functionality

If an alert transitions to a higher-priority area, a (“CAME” message) and a delay time is set for the target area, the initial area initially remains the current area. At the same time, time monitoring is started. Then there are three options:

  • The value remains in the target range:

    After the delay time has elapsed, the target area becomes the current area and a corresponding "CAME" message is generated.

  • The value returns to the initial range:

    The time monitoring is stopped and the initial state is reached again without generating a message.

  • The value transitions to an area of ​​even higher priority:

    A "CAME" message is generated for the original target area. The time monitoring is then no longer active.

    Whether a "CAME" message is then generated for the new area depends on its configuration of the delay time. If a delay time is configured, the cycle described above begins again. Therefore, if there is a delay time, the original target area becomes the current area, otherwise the new area becomes the current area.

    The delay time is only taken into account when a value change happens. If the system shuts down during the delayTime, after a restart the alerts will be immediately triggered.

Note: Only the CAME alert is delayed, the WENT alert is always immediate!
