Hello, I am currently troubleshooting a Profibus communication error involving the new ABB Profibus RPBA-01 REV N. The ACS800 drive is able to communicate with the old RPBA-01 REV G for Siemens PLC. The old version of the ABB RPBA card is still available in the market, but the new card must be used. I have properly set the node address, and the PLC is able to detect the node without any errors being recorded. However, the drive is consistently sending communication errors and flashing. I have attempted to download a new GSD file onto the hardware configuration, but this has not resolved the issue. If anyone has encountered this problem before, your input would be greatly appreciated. Thank you.
Have you thought about reaching out to ABB Technical Service for assistance with this issue?

Hey there, I had a similar issue a while back. It sounds like you've checked the usual suspects like node address and the GSD file. Have you also verified the baud rate and time settings on the card to make sure they match the PLC? Moreover, double-check the wiring; sometimes a reversed data line can be devilishly hard to spot, but it can cause communication issues. Lastly, have you tried to reset both the RPBA-01 module and the Siemens PLC to factory settings and then re-establish the connection from scratch? It might be time-consuming but could help rule out any software glitches.
It sounds like you've tried all the usual steps for this sort of issue, which makes me think the problem might lie elsewhere. You mentioned the drive is flashing with communication errors. Is it consistently flashing a specific error code? That might point directly to the heart of the problem. It could also be useful to double-check if the software version of your PLC is compatible with the new RPBA-01 REV N card. Sometimes, such issues can arise when there's an update mismatch between hardware and software.
