Guidance for MODBUS Communication with the RMS LAN Devices¶
RMS LAN devices (except the RMS-Converter) are based on Little Endian memory organisation (The device firmware provides the MODBUS information starting with the most significant byte.)
When selecting the MODBUS byte order in RMS-CONFIG, the settings are based upon the Little Endian format:
| WordSwap |
|---|
| ByteSwap |
| ByteAndWordSwap |
| NoChange |
When Big Endian format is required, please select the following MODBUS byte order in RMS-CONFIG:
| ByteSwap | WordSwap |
|---|---|
| WordSwap | ByteSwap |
| NoChange | ByteAndWordSwap |
| ByteAndWordSwap | NoChange |
