The tags populate in the right-most window. These tags, which are bound to registers on the PLCs, can be read by LabVIEW. View the Sine tags by expanding Simulation Examples and selecting Functions.NI OPC Servers 2012 Displaying Simulated PLCs Note: If this simulation project is not already loaded in NI OPC Servers 2012, select File»Open… and browse to C:\Program Files\National Instruments\Shared\NI OPC Servers\V5\Projects\simdemo.opf. The project should look like Figure 1.įigure 1. This project simulates PLCs that have already been created and configured in NI OPC Servers 2012. NI OPC Servers 2012 should launch with a PLC simulation project already loaded.With NI OPC Servers 2012, you can create, configure, and view tags that are associated with your PLCs. Launch NI OPC Servers 2012 by selecting Start✺ll Programs»National Instruments»NI OPC Servers 2012»NI OPC Servers Configuration.
