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.

The data communication between PROFIBUS DP master and Modbus master through GT200-DP-RS is shown

below.
