Subject: Application not run by time HH:MM trigger
Posted: Sun Apr 09, 2017 3:22 pm (GMT 5.5)
I can set an application to start and finish with entry time/deadline time fairly easily, but I have the following scenario I need to address:
I need to alert an operator if an application/s has not run/started by a given time - eg, it may be waiting on a predecessor. I'm new to OPC, but from my reading of the manuals I can't see an easy way to do this.
My thinking is maybe create a dummy application X, and make it successor to all applications which need to have been started/completed by a given time. So I set the entry time of X to the cut-off time, and give it a nominal end time of entry + 1 minute. SO with this setup a WTO from X means I'm waiting on start/completion of my critical applications.
HOpe this makes my meaning clearer. Sorry if this is a dumb question, I'm new to OPC. Is there a more direct path ?
