Device Data Base (GSD) File
Overview This PROFIBUS adapter requires a GSD file for implementation.
This file is available for downloading from
http://www.rockwellautomation.com/rockwellautomation/support/networks/g
sd.page
. The GSD file is used by your configuration tool to help you set up your
system. Your configuration tool automatically reads the GSD file and extracts
defaults used in the data exchange. The file is in ASCII format and you can view
it with any text editor.
This device data base file changes when new FLEX I/O modules are introduced.
To use an I/O module not included in the GSD file that you have downloaded,
you need to update the GSD file with a teaching entry for your new I/O
modules.
Go to the GSD website and locate the GSD file for your 1794-APBDPV1
adapter module.
Use the Teaching
GSD Feature The Teaching feature allows a new I/O module to work with a 1794-APBDPV1
adapter firmware. It allows the adapter to support the new I/O module and read
the I/O module’s identity, configuration, and I/O information and work with
the module.
This section involves two steps:
• Create Standard and Teaching GSD Files on page 106 shows you how to
create a teaching and standard GSD file that are required to teach your
adapter to work with any new I/O module. It also provides a description of
the different parameters in a teaching file entry and corresponding byte
information for each parameter.
• Teach an I/O Module to Work with 1794-APBDPV1 Adapter on page
115
provides a step-by-step procedure on how to teach a new I/O module
to work with the 1794-APBDPV1 adapter through the GSD file.
IMPORTANT Before Using the Teaching GSD Feature
To effectively create a teaching GSD file for your module, you need to
be familiar with the I/O data table for your module. The I/O data table
is usually available in the User Manual specific to your module.
For FLEX I/O modules, user manuals are available in the Literature
Library:

Note that each I/O module profile is unique. The examples used in
this document serve to illustrate the Teaching GSD process only.
