What to do if I get a Modbus data range error on my Rhymebus RM6F5 Controller?
- R
  riosruthAug 2, 2025
  If you encounter a Modbus data range error with your Rhymebus Controller, it could be due to two reasons: either the data length in transmission doesn't match the protocol, or the data range exceeds the register length during a write operation. To resolve this, ensure that the data length aligns with the protocol specifications and that the data you're writing stays within the register's defined limits.
