The data movement in the PROFIBUS Slave module (PDPS) is as follows: Input registers (0 - 99) move from the PROFIBUS Slave module to the PROFIBUS Master. 
Output registers (100 - 199) move from the PROFIBUS Master to the PROFIBUS Slave module.
 In 5xxx PDPS Gateways:
The data movement in the PROFIBUS Slave module (PDPS) is as follows: Input registers (0 - 122) move from the PROFIBUS Slave module to the PROFIBUS Master. 
Output registers (200 - 322) move from the PROFIBUS Master to the PROFIBUS Slave module. 
 Note: With the PROFIBUS protocol, input and output nomenclature is always from the stand-point of the master.
