Introduction

The M-Bus ("Meter-Bus") is a standard for remote reading of meters. It is usable for most types of consumption meters as well as for various sensors and actuators. The GW-7828 is specially designed for M-Bus slave device. It offers Modbus RTU communication by three kinds of interface, RS-232, RS-422 and RS-485. On hardware the GW-7828 has two rotary switches for serial port and M-Bus port baud rate. GW-7828 supports Modbus RTU function code 0x03 and 0x04 to read data of M-Bus meters. Through this design, it is easy to communicate with any standard M-Bus slave.
