Additional
information The GW-7552 Gateway is specially designed for the slave device of PROFIBUS DP protocol. It allows the PROFIBUS master to access the Modbus devices. These Modbus devices may be a PLC, a sensor, ICPDAS M-7000 series modules and so forth. In addition, we also provide the utility software for users to configure the GW-7552. By using this module, users can put their Modbus devices into PROFIBUS network very easily.
The GW-7552 Utility helps users to configure the devices, and has following features:
Provide GW-7552 safe value setting Display module parameters of the GW-7552 Show module address configuration of the GW-7552
