OPC Mirror connects OPC servers on multiple control systems and enables two-way data traffic from one system to another. This linkage can be between DeltaV OPC servers, DeltaV and PROVOX servers or several other OPC server combinations. Any data item that an OPC server accepts when adding items is also acceptable in OPC Mirror.
When used with DeltaV, OPC Mirror utilizes SCADA tags which allow companies to take advantage of DeltaV’s configuration, Operator view, and Historization functionality without having to pay for the full price of hosted data values (that is, they are managed separately from DSTs).
OPC Mirror contains the following components:
You can run redundant OPC Mirror clients by installing OPC Mirror on both members of an Application Station pair with the Enable Redundancy for Assigned Modules option enabled. Redundant OPC Mirror clients participate in switchover decision-making for the Application Stations. The OPC Mirror clients inherit their active or standby redundancy roles from the core DeltaV redundancy subsystem. When configuring pipes, set the Hostname field to Local Machine.
