OPC remote server & SIMATIC NET

Hi All,

I'm just making a project using VB.NET SIMATIC NET Siemens and ITS OPC to connect a pc client station to remote server.

More precisely I need to read PLC TAG in my VB.NET application that is the OPC Client connecting to a remote OPC server.

My question is this: Do I need SIMATIC NET installed on both station (client and server)? Or only on server side station.


Thank you very much for your support.

OPC Server need be installed in the Client PC. Tags can be browsed through a network.
