Notifications - How do I (or is it possible) to send a notification at the beginning of an event frame, and a different message at the end of the event frame?

JohnTGE

We are using an event frame to monitor when the OPC interface go down (below a threshold data rate value). If this happens, we want to send out a notification that says "Interface DOWN". When the interface resumes operation (maybe the server got rebooted) and the interface resumes operation (i.e., above a threshold data rate value), and the end of event frame has been attained, we would like to send out a different message saying "Every thing is great now... no need to panic".

Obviously, I could create two (2) different event frames (one for when the interface goes down, and one for when it is functioning properly), but I would prefer to have a single event frame tracking the interface down (and return to normal) event, and have that single event frame trigger two DIFFERENT messages (one at the beginning and one at the end).

 

TIA.

    You can create two notification rules for the same EF analysis, add the same subscriptions to both notification rules, and then set the notify option for one of them to "Event Start" and one to "Event End." Then you can use different formats for each of them.

    Alternatively, you can also use the "Message for Closed Notification" under "Notification Rule Properties" in the formats to add a message when the event frame is closed. This message can be configured (server wide) in the configuration database.

    Sorry to jump on an old reply searching for a solution to this need, but could Aveva add markup to include/exclude content in-between? This would be a far more elegant and flexible solution to the options listed above.

    e.g. <openonly>foo</openonly> always sent stuff <closeonly>bar</closeonly>
