OPC Server Redundancy

General Discussion
1

We have two SCADA Servers in redundant mode. Both SCADA Servers have OPC servers running on them with similar tag configuration.

Can FSQL connect to this OPC servers in a redundant manner. i.e. If one OPC server fails can it move to the partner OPC server and vice-versa?

If this is not possible do I need to buy some third-party OPC Redundancy broker etc.?

Hi,

Yes, you would definitely need a 3rd party application for the OPC redundancy. There’s no way in FactorySQL to chain or link servers for failover.

Hi Vipulss,

To support OPC Server-level redundancy, you could add in an OPC Redundancy Broker.
