You can probably find most of the answers you are after in the KB or online sells used surplus products. If you have any more questions, I'd be happy to help. The only draw back I can see with this approach is that you would have to manage project updates on both systems with some care, using a change procedure.

This would enable both systems to exchange data and see the entire tag database of the other side. And do the same thing vice versa for the other side.Īlthough a better solution would be to upgrade the v7.10 system to v7.20, then configure a global project (a combination of the two projects). I think one solution for you is to enable the OPC Server function on the v7.20 Server, then configure OPC Client (OPC driver) with variable tags you want to poll configured in the v7.10 system. It is usually only used during upgrade process. It is possible for a v7.10 client to communicate with a v7.20 server by adding the following parameter on the v7.20 server:Īlthough it is not recommended to leave this permanently on. There were quite a few changes in v7.20 to the tag architecture with tag extensions being added and security enhancements. The first hurdle is the different versions, v7.10 and v7.20. Both products are fundamentally the same in terms of network communications. The communication issue is not due to the Vijeo Citect / CitectSCADA mix.
