PROFINET Data Exchange
6.1
Overview
PROFINET is the open Industrial Ethernet standard for automation from PROFIBUS and PRO-
FINET International. The PROFINET IRT device provides PROFINET IO Isochronous Real
Time Communication.
PROFINET makes a clear distinction between fast cyclical data,
IO Data
, and acyclical data,
Record Data
. PROFINET IO Data corresponds to what is generally referred to as
I/O Data
in
the Anybus X-gateway User Manual. PROFINET Record Data corresponds to what is referred
to as
Parameter Data
.
PROFINET IO Data (I/O Data)
PROFINET IO Data is exchanged cyclically and is built up by I/O modules. The actual I/O con-
figuration is determined by the PROFINET IO Controller. The modules are mapped to the Input
and Output Buffers in the order of their slot number.
PROFINET Record Data (Parameter Data)
Record Data is exchanged using acyclic Record Data Read/Write requests.

GSD File
All PROFINET devices are associated with an XML-based
GSD
file. This file contains informa-
tion about the basic capabilities and configuration options of the device.
The latest version of the GSD file for the Anybus X-gateway PROFINET IRT (2.32) can be
