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:
