Storage gateway (Modbus firmware support only)

Configurable gateway (Modbus firmware support only)

4.5.1 Simple protocol conversion mode

Simple protocol conversion: convert The Modbus RTU data to TheModbus TCP data, or the

Modbus TCP data to the Modbus RTU data, and realize the interoperability of the Ethernet Modbus
data with the serial Modbus data.

Simple protocol conversion can work in TCP server mode or in TCP client mode, whether

working on TCP server or TCP client can only exist a Modbus master.

The gateway works in TCP server mode:

When the Ethernet side is the Main Station of Modbus, only Socket can be connected all
the way (to prevent data conflicts);

When the serial port side is the main station of Modbus, up to 6 Modbus TCP from the
station can be connected;

The gateway works in TCP client mode:

Ethernet side as the Main Modbus station, serial port side theoretically supports up to 128
RTU from the station;

Modbus answer timeout configuration: range: 0-65535ms, default: 500ms.

4.5.2 Multi-host mode

For simple protocol conversion, there can only be one Modebus master, a feature upgrade, when

multiple hosts access at the same time Modbus gateway will be bus occupancy scheduling, thus
