Figure 16 Data exchange between Profibus master device and GW-7552
The GW-7552 downloads the parameter and configuration from Profibus master
device to be the module parameters. The GW-7552 and Profibus master device
have different data type and data address, the GW-7552 can transfer different data
format to Profibus master device through module parameters. When the GW-7552
acts as a Modbus master device, it will send DI、AI data to input data area of
Profibus master device and it will save data that receives from Profibus master
device to internal DO、AO memory space, as shown in figure 17
、 18.
