I'm new to Ethernet/IP and am running into an issue attempting to control a Siemens VFD using this protocol with LabVIEW. I am using the read/write single attribute VIs, and am successful in reading information from the drive, however I seem to be unable to write a setpoint and 'run' command. I don't receive errors from LabVIEW, but the drive does not respond. Siemens technical support has been unable to find an issue with my setup, so they believe it to be LabVIEW-related.
I have included a screenshot of my code, the EDS file, and a screenshot from the vfd manual discussing the assemblies.
I have the VFD parameters set for the ODV profile and Telegram 1. Again, I can read values fine, so it seems the drive is configured properly.
Am I missing something obvious here?
Thanks in advance.
