Configure Output points

IMPORTANT:
Since the output tag values reach the controller with variable latency, they cannot be used for applications requiring real-time update. The output tags are meant for monitoring purposes only.
You can trigger Output points in the following ways:
  • By configuring a separate trigger point.
    The Output point must have the same point source as the interface,
    FTME
    . The trigger point can be associated with any point source. The point type of the trigger point and the point type of the Output point may differ.
    You can associate an Output point with a trigger point by setting the
    Source Tag
     attribute of the Output point to be the same as the tag name of the trigger point.
    Any scan tag that is referenced in the
    Extended Description
     or
    Scan Tag
     attributes must not be high-speed or have a scan rate higher than 1 second. Otherwise, the module will generate an error and you will not be able to save your point.
    An output is triggered when a new value is sent to the snapshot of the trigger point. The new value does not need to be different than the previous one that was sent to the snapshot to trigger an output, but the timestamp of the new value needs to be more recent than the previous value.
  • By writing a new value to the snapshot of the output point itself.
    The new value does not need to be different from the previous one to trigger an output, but the timestamp of the new value must be more recent than the previous value.
