Modbus Troubleshooting

Use when Modbus IO misbehaves (timeouts, extra data, wrong values).

Quick checks

  • Verify deviceid/unitid on every call; wrong unit → timeouts.
  • Add pacing (messagewaitmilliseconds) and avoid immediate post-write polls.
  • For RTU-over-TCP, flush/reset framer/buffer; reconnect on extra-data.
  • Log address/unit/function and raw words to spot endian or offset issues.
