Tip: You must use one of the following products to create the OPC topic: RSLinx Classic Single Node, RSLinx Classic OEM, or RSLinx Classic Gateway. RSLinx Classic Lite does not support OPC communication. For more information about using RSLinx Classic, see the RSLinx Classic documentation.
To create an OPC topic for the emulator:
1. Open the Chassis Monitor, and make sure your emulator is running.
2. In RSLinx Classic, open an RSWho window (click Communications > RSWho). The emulator should be visible in the RSWho window. If it is not, make sure there is a communication driver for the emulator.
3. In the RSWho window, right-click the emulator, then click Configure New DDE/OPC Topic. This creates a new OPC topic, and displays the DDE/OPC Topic Configuration window with a new topic for the emulator.
4. Click Done. This closes the DDE/OPC Topic Configuration window and saves the topic for your emulator.
