Description
The GW-7553 PROFIBUS DP to Modbus TCP Gateway allows ProfiBus DP master devices to communicate with Modbus TCP protocol devices such as a sensor, PLC or the ET-7000 and I-8KEx-MTCP series. It also supports Modbus ASCII / RTU protocol for connection to other Modbus devices, such as the M-7000 series.
Configuration of the GW-7553 is simple, as the device has a built-in web server, which allows the module to be setup using a web browser.
