Modbus RTU and Danfoss

Recommended Posts

  • MVP 2023

I split this request off of this thread, which contained a lot of information regarding talking to a Danfoss drive from a Vision controller-


It also had a post by me with detailed instructions on how to get started with the software and hardware tools needed to troubleshoot Modbus communications.

Miguel - start by looking at the Example Programs in the U90 software.  They're under the Help menu and there's one for Modbus Master.  You'll have to figure out which registers in the FC51 you need to write to.

If you do a little research and post what you find here we can help.  Also, upload any PLC programs you've done with questions.
