Features
GW-7552-M is a PROFIBUS to Modbus RTU Gateway designed for the slave device of PROFIBUS DP protocol. GW-7552-M allows a PROFIBUS master to access Modbus devices which may be PLC's, programmable controllers, sensors or Modbus RTU Data Acquisition modules like the ICP DAS M-7000 Series modules. GW-7552-M comes with an easy to use setup utility software for configuration.
