Where can i find usefull information for OPC connection to 800xA?I
Voted best answer
I suggest to use PLC connect option in 800xA to connect 3rd party PLC's via OPC.
There is a document describing PLC Connect configuration ( 3BSE035041-510 )
You can also check the attached link for Overview description of PLC Connect option of 800xA
on page 51 of the 800xA system guide. Hope this helps. Carsten
