Features
The GW-7553 PROFIBUS to Modbus TCP Gateway is specially designed for the slave device of PROFIBUS DP protocol. It allows the PROFIBUS master to access the Modbus TCP devices. These Modbus devices may be a PLC, a sensor, the ICPDAS I-8KE4-MTCP module and so forth. In addition, the GW-7553 module built-in web server, the user can set the module by web browser. By using this module, users can put their Modbus TCP devices into PROFIBUS network very easily.
