Concrete Examples

Can someone point me to a concrete example of how to parse an .njlog file to read modbus-rtu data?

Ideally this can be done in a language like python, but even if its in jancy, a full example would be wonderful.

Here is a blog post on the subject: https://ioninja.com/blog/walking-your-log/

It doesn't dive into the internals of parsing Modbus RTU frames themselves, but you'll be able to enumerate and extract all Modbus RTU master and slave frames from your .njlog file -- and take it from there.
