Reading 3rd Party OPC variable in CBM
I've got OPC link with Siemens S7, it communicates to xA V4.1 to display status and generate soft alarm on PPA, my requirement is to read some of the variables to manipulate logic in CBM and also trigger DO for the audible alarm.
I hope it's possible, someone please help me how to do it.

Inorder to transfer data from one control network to other control network like Mod300 Data base to 800M Application level or from PLC Connect(3rd party interface) to 800M Applications, 1st ensure data is available on 800xA under the corresponding control networks like for 800M we call it as Control network & for PLC connect we call it as Generic Control network.Once you sure you are getting data under respective control network please follow the attached doc.
You can do that with Property Transfer, a short search in this database should give you more information. But keep in mind that this transfer depends on the 800xA system running. If there could be any harm if the connection is down add a watchdog or use a direct connection between the PLC's.
