Introduction Page

GW-7552 ~ NEW ~
PROFIBUS/Modbus Gateway

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.

Applications

Industrial Automation
Factory Automation
Process Automation
Etc…
