Set the Default Authentication Level to Default. Make sure “Enable Distributed COM on this computer” is checked Right click on My Computer, and select Properties. Launch the DCOM configurator by clicking on the start menu then typing “dcomcnfg”Ĭ. Step 1: Configure DCOM Settings on both computers: 1) On BOTH ComputersĪ. A second Windows computer with Ignition installed.A computer with RSLinx Classic and RSLogix Emulate (for my testing I used 5000).Two computers (or VMs) that can communicate to each other using IP addresses and computer names.Note: Because this uses OPC-DA (because RSLinx does not yet support OPC-UA), this will only work on Windows (unless an OPC-DA client has been released for the linux version since last I used Ignition) While doing testing I found a way to use the OPC-DA connection to create a link between 2 computers and read values from an RSLinx topic I had created to an emulated PLC.
