Anybus CompactCom 40 - PROFINET IRT Transparent
Ethernet
3. Basic Operation
3.1. General Information
3.1.1. Software Requirements
Generally, no additional network support code needs to be written to support the Anybus CompactCom 40
PROFINET IRT, however due to the nature of the PROFINET networking system certain things must be taken into
account:
• Up to 32767 ADIs can be represented on PROFINET.
• ADI names, types and similar attributes cannot be accessed via PROFINET. They are however represented on
the network through the built in web server.
• Up to 5 diagnostic instances can be created by the host application. An additional 6th instance may be created
in event of a major fault.
• For conformance reasons, the host application must implement support for network reset types 00h (Power-
on) and 02h (Power-on + Factory Default) in the Application Object (FFh).
• PROFINET in itself does not impose any particular timing demands when it comes to acyclic requests (i.e.
requests towards instances in the Application Data Object), however it is generally recommended to process
and respond to such requests within a reasonable time period (exactly what this means in practice depends on
the implementation and the actual installation).
• The order in which ADIs are mapped to Process Data is significant and must be replicated in the IO Controller
when setting up the network communication. In case of a configuration mismatch, see
Mismatch (page 17) for more information.

3.1.2. Electronic Data Sheet (GSD)
On PROFINET, the characteristics of a device is stored in an XML data file. This file, referred to as the "GSD"
file, is used by PROFINET engineering tools when setting up the network configuration. HMS Industrial Networks
provides an example GSD file, which must be adapted by the user to suit the application. To adapt the GSD file,
use the HMS PROFINET GSD Generator Tool which can be downloaded from www.anybus.com.
NOTE
A GSD checker tool and a GSD upgrade tool is available to PI members on the PI website.
