Hello all,

Just looking for a small clarification before I go down a blind alley…

The marketplace page of the OPC-COM module specifies that it “Supports OPC-DA 2 & 3, for Windows only”. Does this mean I wont be able to use the module on a linux ignition installation? Or does it mean that regardless of which Ignition installation I’m using, I can only connect to OPC-DA servers on windows?

Thank you.

The OPC-COM module can only be installed if the Ignition gateway is running on Windows.
