How to Configure Alarm from PLC connect into ABB800xA
Hi, I have never configured alarm in ABB800xA prior to this so I am missing some basic knowledge here.
I have list of alarms coming from 3rd party Siemens PLC via PLC connect into ABB800xA. I can read all alarms fine under PLC connect but I dont know how I can configure this alarms to be displayed on ABB 800xA alarm banner?
I read few things about adding Alarm and event list configuration aspect, I added the aspect under PLC connect config but not sure how you can link the aspect with list of alarms under PLC connect?
Can someone please guide me on best way to achieve this?

I'm guessing that you're not reading "alarms" - you're reading Alarm Bits via the OPC-DA (Data Access) server.
Before you can create Alarm lists you have to generate alarm and event messages. You can do this in one of two ways ...
- Use an OPC-AE (Alarm and Event) server to collect the alarm messages generated in your PLC and send then to an event collector in 800xA. IIRC you're using Siemens S7, so you probably don't have an OPC-AE server.
- Use the 800xA system to generate AE messages based on the Alarm bits that you read from the OPC-DA server. This feature is called "Soft Alarms" and you'll need a soft alarm service and "Alarm Expression" aspects to generate Alarm Messages.
Once you have a source of alarm messages, using the alarm lists and alarm configurations aspects will be easier. But you'll probably find it easier to use the default alarm list configurations.
Hi Rob, Thank you so much for your response.
You pointed out corrently that I dont have Simatic A&E OPC server as I am using Simatic NET therefore I used second option suggested.
I used Soft Alarm service under servvice structure and added Alarm Expression aspect (configured as per ABB800xA 5.1 Configuration Manual, Alarm & Event Section) under each tag under Control Structure/PLC connect service so now when value for particular boolean tag is changing from Simatic NET OPC servce, I am getting alarm on ABB800xA alarm banner.
Thanks once again.
