Figure 12 Data exchange between PROFIBUS Master device and GW-7553-B /
GW-7553-M
The GW-7553-B / GW-7553-M downloads the parameter and configuration from
PROFIBUS Master device to be the module parameters. The GW-7553-B / GW-
7553-M and PROFIBUS Master device have different data type and data address,
the GW-7553-B / GW-7553-M can transfer different data format to PROFIBUS
Master device through module parameters. When the GW-7553-B / GW-7553-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
、
AO memory space
