What is/are your question(s)?

When submitting a log for a previous issue I noticed I am getting constant Modbus exception errors about every 8 minutes in the Genmon log. Should I be concerned? Do I need to reset something?

This is expected behavior and as been addressed in past issues as well as the known issues wiki

This is not related and will not change the behavior of modbus exceptions, but you are not running the latest version of genmon. The latest is 1.19.05

@SRFurst you may also want to note this indicates that your controller is an Evolution 2, not an Evolution (1.0). There are some differences in capabilities between the two so it is at times an important distinction.

Thank you. I DID search the Discussion for Modbus Exceptions and didn't find anything before I asked. :)

No worries. You have to search the issues and discussion history. When the project started github did not have a discussion area so the issues area contains history that predates the use of the discussion forum.
