9 PROFINET
®
PROFINET is a data communications protocol for industrial automation and processes. PROFINET IO defines how
controllers (IO controllers) and peripheral devices (IO devices) exchange data in real time. The standard is maintained by
PROFIBUS & PROFINET International (PI) , an organization headquartered in Karlsruhe, Germany.
Only the DXM700, DXM1000, and DXM1200 Controller models support PROFINET IO.
9.1 General Station Description Markup Language File
A PROFINET General Station Description (GSD) file is a description of an IO device provided by the device manufacturer in
an XML format (GSDML.xml).
The GSD file is a standardized way of describing the device information to engineering tools and the IO controller and can
work across a variety of tools as a standard set of device information.
9.2 DXM PROFINET IO Data Model
The PROFINET IO data model is based on the typical, expandable field device that has a backplane with slots. Modules
have different functionalities.
Modules are plugged into slots. In the PROFINET IO data model Slot 0, Subslot 1 is reserved for the Device Access Point
(DAP) or network interface.
•
Inputs Integer Module sends integer data to the PLC
•
Inputs Floats Module sends floating point data to the PLC
•
Output Integer Module receives integer data from the PLC
9.3 Configure the DXM Controller for a PROFINET IO Connection
To use PROFINET, follow these instructions to configure the DXM700 or DXM1200.
1. Using the DXM Configuration Software, go to the
Settings
>
Ethernet
screen.
2. Select
Enable PROFINET
.
3. Save the configuration file and upload it to the DXM Controller (see
Save and Upload the Configuration File
on p. 16).
After PROFINET is enabled, the IP address for the DXM Controller is controlled by the PROFINET host. The LCD
display and DXM Configuration Software no longer control the setting of the IP address. The PROFINET IP address
settings are invisible to the LCD display and the DXM Configuration Software.
The PROFINET data type and data size to/from the DXM Controller is configurable. The PROFINET data is processed from
the Local Register of the DXM Controller.
Configure the Local Registers to match the PROFINET module definitions in the host PLC.
9.3.1 Save and Upload the Configuration File
After making any changes to the configuration, you must save the configuration files to your computer, then upload it to the
device.
Changes to the XML file are not automatically saved. Save your configuration file before exiting the tool and before sending
the XML file to the device to avoid losing data. If you select
DXM
>
Send XML Configuration to DXM
before saving the
configuration file, the software will prompt you to choose between saving the file or continuing without saving the file.
1. Save the XML configuration file to your hard drive by going to the
File
>
Save As
menu.
2. Go to the
DXM
>
Send XML Configuration to DXM
menu.

•
If the Application Status indicator is red, close and restart the DXM Configuration Tool, unplug and re-plug in the
cable and reconnect the DXM to the software.
•
If the Application Status indicator is green, the file upload is complete.
•
If the Application Status indicator is yellow, the file transfer is in progress.
The device reboots and begins running the new configuration.
