We have the Control Architecture with the two OPC server. We would like to switch between the OPC Server based on condition. The objective is to move the all tag from OPC server A to OPC server B by automated script based on Tag bool Value. We have 500 tags right now but for scalability I would like to know what is efficient way.
I found following option A so far which write the OPC server parameter on UDT level. This will solve the objective, but was hoping if we could do on Gateway level changing the OPC server based on tags value.
OPC connections and References Tag - Ignition - Inductive Automation Forum
In my project, I have two OPC connections from one pair of TwinCAT controllers (e.g. 1A and 1B). And I have approximately 250K OPC tags in one tag provider. In terms of redundancy, if i want to switch all the tags from one OPC connection to the other by changing OPC Server name using Reference tag naming 1A and 1B. Is it possible and having any impact on performance of Ignition.
