Application example of PROFIBUS to Modbus
In this example the GW-7552 acts as a Modbus slave device. When the GW-7552
module receives a write DO Modbus command from PC’s COM Port, the GW-7552
module can send the message to the input data area of PROFIBUS master station.
When the GW-7552 module receives a read DI Modbus command from PC’s COM
Port, GW-7552 module can refer to the output data area of PROFIBUS master
station to produce response message and send it to PC’s COM Port.
