Dynamic alarm messages with Compact HMI
I am working with an AC500 in combination with Compact HMI at the moment. We decided to generate the alarms in Compact HMI without the use of OPC AE so we use the Alarm Event Configuration Aspect in Compact HMI to generate our alarms. I am using the Alarm Event Configuration Aspect in the control structure to configure alarms from PLC Connect signals. Is it possible with this aspect to generate dynamic messages? For example: "Valve 15 is 97% open", where the 97% is a dynamic value from another signal.
I tried a solution with the String Builder Aspect and a Property Transfer Aspect. I made the dynamic message with my String Builder Aspect (this works fine) and then I used the property Transfer to write the value of the String Builder Aspect to the Message1 property of the Alarm Event Configuration Aspect. This works, but in my alarm and event list the old message comes up. I have to do a new deploy of my control structure to get the new message in my alarm list. So, at the end this is not the solution. Are there any other options?
i did ask this question two weeks ago, but I am still looking for a solution: http://www402.abbext.com/How-make-dyn...
I had contact with several ABB specialists about this and as far as I know now this is not possible. The problem with the combination of the Alarm Event Configuration Aspect in combination with PLC connect is that you have to deploy the RTDB database at every change. And you do not want te deploy the RTDB database multiple times a day. Our solution was to integrate a lot of signals in trend displays, so people can analyse the alarm list next to the trends.
Other solution is to use OPC AE and use another program to make the alarms. (for example Codesys OPC AE server for the AC500).
