There are 4 prodution lines here, and I want take some tags from these lines to the Utility Department WinCC server (there is already a WinCC project in this department, and it is connected with its plcs).

I am thinking to use the Ethernet communication like between server and clients. But I am not sure it does work, and how to do it.

 

The tags in WinCC are exposed through OPC (OLE for Process Control / Openess, Productivity, Connectivity). To bridge tag values to a remote utility department you can use an OPC Bridge software module. DataWorX32 allows you to configure registers that bridge the values on-change to the target destination.

This provides an OPC-to-OPC connection. Depending on the challenges in your network, DataWorX allows you to communicate OPC over standard Microsoft DCOM, OPC tunneled over IP or OPC over XML.

The development package can be downloaded from:

In case, as aposed to a constant data stream from server to server, snapshots of your server data needs to be transfered based on specific process conditions, an alternative should be explored: BridgeWorX. It's a .NET product, which allows you to configure business logic block diagrams executed as transactions. Triggered by your time schedules or change in the OPC values e.g. "end of batch signal" or other business conditions.

Good luck!

I am not sure what you are trying to accomplish here but I will give it a stab. It looks like what you are trying to do is simply read and write tags from one WinCC Server to another. Unlike many of the other SCADA packages on the market there are many ways to accomplish this. The WinCC help system will explain in detail on how to do this. Just simply go to the Index and type Server-server.

Hi guys

I found out a good solution for this problem, the OPC client.
