Call OPC UA Methods from SAP DM via SAP Production Connector

[stephan_madlmayr]

Hi together,

during a current SAP DM implementation we would like to call a existing OPC UA Method that simply updates a specific tag on the PLC. Back with the PCo this was possible by using the ENP (Enhanced Notification Processing).

I was wondering if something similar also exists for the SAP Production Connector? Or what would be the approach to do this otherwise?

Thank you in advance,
Stephan

Hello Stephan,

Yes, it does! I briefly show it in action here.

You can check Configure Shop Floor Services (OPC UA Methods) for more details.

A simpler option to write tag values would be to use Write Indicators or Write Setpoints services below in a Production Process.

Br,

Manoel

Thank you very much Manoel! I have added the OPC Method in the app "Manage Service Providers" and created a Production Process in the ProdCon Runtime. When I execute the production process I get an error regarding user authentication, is it mandatory to set up principal propagation to call OPC UA methods?
