Page 24: Working Principle
GT200-DP-RS Universal Serial/PROFIBUS DP Gateway User Manual 5 Working Principle The GT200-DP-RS has an input buffer and an output buffer. The data transmission between serial devices and PROFIBUS DP master through GT200-DP-RS is established by mapping address. 5.1 As Modbus Master When the serial interface of the GT200-DP-RS is configured as Modbus master: The data read from Modbus slave devices by function code 01, 02, 03 or 04 is stored in the input buffer then transmitted to PROFIBUS DP master. - Page 25 GT200-DP-RS Universal Serial/PROFIBUS DP Gateway User Manual The output buffer can be regarded as Input Status (1x) area and Input Register (4x) area for the Modbus master. The data of the output area can be read by function code 02 or 04. The PROFIBUS DP master writes the data to the output buffer.
