The tGW-724/734 modules are Modbus TCP to RTU/ASCII gateways that enable a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices through an Ethernet network, and eliminates the cable length limitation of legacy serial communication devices. Meanwhile, the modules can be also used to create a pair-connection application (serial-bridge or serial-tunnel application), then route data over TCP/IP between two serial Modbus RTU/ASCII devices, which is useful when connecting mainframe computers, servers or other serial devices that use Modbus RTU/ASCII protocols but without Ethernet capability. |
