2.1. Overview
The Anybus X-gateway PROFIBUS Master Interface has complete PROFIBUS DP Master functionality according
to IEC 61158. The PROFIBUS master interface allows up to 125 PROFIBUS slaves to exchange data with another
network.
The interface exchanges data via two memory buffers:
Input Buffer
Contains data coming from the PROFIBUS slaves.
Output Buffer
Contains data going to the PROFIBUS slaves.
Figure 1. Data flow
The PROFIBUS master interface can exchange up to 512 bytes of I/O data in each direction. The actual byte sizes
of input and output data are set in the network configuration created with a PROFIBUS network configuration
tool such as Anybus NetTool for PROFIBUS.
The output data area can optionally include general status information from the PROFIBUS network. See the
Anybus X-gateway User Manual for more information.
