Overview

The Anybus X-gateway PROFIBUS Slave Interface has complete slave functionality according
to the DP-V1 expansions of EN 50170, supporting standard DP functionality as well as acyclic
Class 1 and Class 2 services.
The interface exchanges data via two memory buffers:
Input Buffer
Output Buffer
Fig. 1 Data flow
Data from the X-gateway can consist of cyclical (DP) and acyclical (DP-V1) I/O data. The
interface can exchange up to 244 bytes of I/O data in each direction, although the total data
size (input + output) cannot exceed 344 bytes. The actual byte sizes of input and output data
and the amount of cyclical versus acyclical I/O data are set up in Anybus Configuration
Manager to match the application.
