HI, I am using a Simotion D425-2 DP connected to an ET200SP and then to a pneumatic valve system through Profibus. I am using this system to run a tension control algorithm which I was successfully able to implement. I recently modified the program to include some Pneumatic actuation and after doing this the PLC sometimes goes into stop mode while running the program, while throwing an error 'Profibus DP3: Station recovery, station-3' I have also attached the diagnostic buffer. Any ideas what this error means and how I can debug it? Thank you AttachmentDevice Diagnostics 2.txt (557 Downloads) |

Possibly related to this:
You may want to investigate installing some additional fault handling OBs to help prevent all the PLC stop events. While not directly related, this forum post may lead you towards a solution: https://support.industry.siemens.com/tf/WW/en/posts/recovery-from-a-profibus-device-failure/57716 It may also be related to have Profidrive diagnostics configured without error handling OB's to prevent PLC from stopping during normal drive startup from power up to reset to ready to run and running and eventually e-stop or fault activation.

Any idea, how I can incorporate this in Simotion scout TIA? |
