Hello aamirawan; Unless there was a change in the CPU configuration or memory, most Profibus failures on a previously working systems are physical in nature. The following article, from Profibus International (PI), describes the 5 most frequent issues that should be checked when you face such problems: https://us.profinet.com/top-5-reasons-your-profibus-network-failed/ Very frequently multiple node loss will be due to termination problems. You must ensure that the end nodes (the first and the last nodes on the bus) on a Profibus network have a termination switch ON and always powered. The termination attenuates reflections on the bus that can interfere with the Profibus controller (the CPU) and data exchanges. Check this first. Hope this helps, Daniel Chartier |

Alright but could you please answer my question about the IM modules configuration mismatch and why was it even working in the first place? Is it supposed to work? Also what happened to the gsd files? |
