I have a Siemens S7-300 CPU going to used profibus to talk to a GE drive AF-650. I was wondering if someone could help me out to understand the PPO type? Which one should i use. I want to tell the drive to turn on and off and send speed ref to the drive. as well as get if the drive is running what speed is going, voltage or current, any fault on the drive.
Thanks for your help
