Instead I ordered the Profibus module for the MM4 - I was up and communicating with the drive in 15 minutes. Probably the only thing I had to think much about was which telegram I wanted to use. I needed accurate RPM and current sensing on both drives - it worked very well for what I wanted to do. I know there is a block for controlling the Micromaster via Profibus.
