The GW-7553 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, we also provide the utility software for users to configure the GW-7553. By using this module, users can put their Modbus TCP devices into PROFIBUS network very easily.
