ATV630 is accessible via DP network, which means that its network settings GSD-file are correct. On the drive side PPO profile is set to 101 (Telegram 101). Telegram 101 is configured in HWConfig with required parameter addresses. When I monitor peripheral addresses online I don't see any data (status word, speed etc. is zero) What might be the problem?

Is data type correctly addressed while reading data from slave? Have you configured correct address of drive? Please check.

And the question is: what else do I need to configure in HWConfig and on the drive side to get data from it? I plan to access data with SFC14/15. Right now I monitor peripheral addresses of the drive in HWConfig just to check if any data is available. PISCEAN 2010 anton.narbut Hi all!
