Masterdrive on PPO4

Rouhullah Posts: 11 Rating: (0)	Getting right on the point, can anybody please help me with details of using PPO4 profibus profile with Masterdrive VC. Like I have seen plenty of results of operating the drive with PPO3, but none with PPO4. Specifically, I am looking for, which control word does what (there must be some manual describing this, but I am unable to find it), and what does the drive (slave) replies upon receiving the telegram. Thank you.

There is no special assignments of sended/received words to/from drive using any PPO-type. The only thing is bit 10 of first word sended to the drive always must be 1 (so converter accepts process data). All other words/bits you may freely interconnect inside drive. You may read about this in the manuals, chapter 8.2.7.2: VChttp://support.automation.siemens.com/WW/view/en/13472409 MChttp://support.automation.siemens.com/WW/view/en/13472407
