Does NI currently have a Modbus .NET library (siilar to the LabVIEW library). I need to talk to a PLC over modbus, and my control application will be in.NET.
I'd like to not have to user labview or compile the VIs into a .NET interop assembly (don't want to require having the labVIEW runtime on the controlling PC).
IDoes NI support modbus over any language other than LabVIEW?
Unfortunately, NI currently does not offer a Modbus .NET library. It sounds like you have already looked into some of the recommended alternatives from the NI side of things as well. While I havent had a chance to use any specifically, I know there are quite a few 3rd party modbus libraries which you could probably use to get the program done in C# without the LVRTE. I would recommend that you post this request on either the Measurement Studio or Additional NI Software Idea exchange pages. Our R&D department frequently adds new features from popular suggestions. Best of luck!
