Sharing data from a distributed system through OPC

[nmnogueira]

Hi all,

I have a distributed system consisting of two redundant systems, and I need to make all the data available to an outside server.
My questions:

• Is it possible to share the data from System1 and System2 through the OPC server of System1?
• It it possible to install an interface server, running a Remote OPC server driver which will make the data from both systems available to be read?

Thank you!

A WinCC OA process can only connect to one system at the time.

It is possible to share data for distributed systems using a WinCC OA OPC server.
If it can be used in your project depends on the WinCC OA version and which OPC server (OPC DA, OPC A&E, OPC UA, OPC HDA) you are using.

Please give more detailed information (WinCC OA version, OPC server).
