Hi Eswar,
To Point 1: MII can pull (query) the OPC tag data on a specifiied interval and render the data in MII UI content.
To Point 2: Technically, the RSLinx OPC Server can serve multiple Clients. For the landscape:
What is the archtecture:
- One RSLinx, One PCo installed on same PC (should be a server class machine)
- One RSLinx, One PCo, PCo installed on a different PC (will require DCOM security configuration for remote OPC connection)
- One RSLinx, Many PCo on different PC (DCOM configuration required for remote OPC connections)
