Decentral Peripherie: Is Im153-2ba02 compatible Including Bm195-7ha/7hb?

Is IM153-2BA02 compatible with BM195-7HA/7HB? 
Im having a bus fault and "module configured but not available", despite IM153-2 and profibus connection both verified ok.
Now im doubting IM-BM compatibility after I read some versions can be incompatible.
Thanks for any response!

IM153-2BA02 and BM195-7HA/7HB Compatibility & Bus Fault Troubleshooting

Yes, there are known compatibility issues between certain IM153-2 versions and BM195 backplanes, specifically the 7HA/7HB models. While your IM153-2BA02 should be compatible, the "module configured but not available" error and bus fault indicate a potential problem.

Here's what to check:

  • Firmware: Ensure both the IM153-2 and the BM195 have the latest compatible firmware. Older firmware can cause issues.
  • BM195 Backplane Version: Verify the exact BM195 version. Some revisions require specific IM153-2 firmware.
  • Module Placement: Ensure the IM153-2 is inserted correctly and firmly into the BM195.
  • Power Supply: Check the BM195 power supply is delivering stable 5V DC.
