Figure 16 Data exchange between Profibus master device and GW-7552-B /
GW-7552-M
The GW-7552-B / GW-7552-M downloads the parameter and configuration from
Profibus master device to be the module parameters. The GW-7552-B / GW-
7552-M and Profibus master device have different data type and data address, the
GW-7552-B / GW-7552-M can transfer different data format to Profibus master
device through module parameters. When the GW-7552-B / GW-7552-M 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
