Industrial Ethernet Serial Gateway

Modbus Serial/TCP Series

3.3.1 Mode selection

Now Modbus Serial/TCP series gateway supports four operating modes:

Modbus RTU slave mode——Modbus TCP master communicate with Modbus RTU slave through the

gateway;

Modbus RTU master mode——Modbus RTU master communicate with Modbus TCP salve through the

gateway.

Modbus ASCII slave mode——Modbus TCP master communicate with Modbus ASCII slave through the

gateway;

Modbus ASCII master mode——Modbus ASCII master communicate with Modbus TCP salve through the

gateway.

Operating mode of Modbus Serial/TCP series gateway is defined by the role of master or slave of serial

equipment, for example, when you want to achieve the communication between Modbus TCP master devices and

Modbus RTU/ASCII slave devices, users need to select “RTU/ASCII slave mode” of Modbus Serial/TCP series

gateway.
