@jon.slavic I may have gotten the response to decode properly by trimming the capture to only show the response, and using the following Modbus settings.
The checksum seems to be correct as well. I’ll provide the .sal file here.

As a first step, can you confirm if the results shown above are you what you expect for the response?
If so, your issue might be related to the GitHub Issue post below, which we’ve recorded for the Modbus analyzer.
