FC 300 DeviceNet and Allen Bradley Control logix 5550
Introduction
This application note describes how to set
up DeviceNet communication between a
Danfoss FC 300 frequency converter and
1756-DNB DeviceNet Scanner from Allen
Bradley. It is assumed that you have some
knowledge of RS Logix, the DeviceNet
Scanners and ladder logic.
This note describes:
z FC 300 DeviceNet card
z Configuration of the FC 300 with RS
Networx
z ADR - Auto Device Recovery
z I/O communication with RS Logix 5000
z Explicit messages with RS Logix 5000
FC 300 DeviceNet card
The photo shows the DeviceNet card
which can be installed in FC 300 Series.
NOTE!:
The examples do not describe all the
functions needed for a real application, for
example error handling.
The examples are based upon that a RS
Logix5000 project has been created, and
the 1756-DNB has been added to the I/O
configuration.
Details of some of the components/
software:
FC 300 with DeviceNet version 2.5.
1756-DNB Series A Firmware Revision 6.002
RS Networx version 5.11.00
RS Logix 5000 version 13.00.00

DeviceNet connection
DeviceNet termination
Termination resistors should be installed at
each end of the bus line.
The resistors must be mounted between
terminal 2 CAN_L and terminal 4 CAN_H and
should have the following specification:
121 Ohm, 1 % Metal film and 1/4 Watt
Cable length
Baud rate Max. total cable length [m]
125 kBaud 500
250 kBaud 250
500 kBaud 100
Address and baud rate setting
Dip switch 1-6 set the DeviceNet address/
Mac ID and 7-8 the baud rate.
Switch 6 is the Most Significant Bit (MSB)
and Switch 1 is the Least Significant Bit
(LSB).
When setting the address/Mac ID you must
ensure that each device on the network has
a unique address. The Baud rate can be
read in parameter 10-01 Baud rate Select
and the address/Mac ID can be read in
parameter 10-02 Mac ID.
NOTE!:
Switch off the power supply before
changing the hardware switches.
LEDs
For the Module Status LED:
1 . When the LED is off, no power is applied
to the option.
2. When the LED is green, the device is
operational
3. When the LED is flashing green, the
device is in standby
4. When the LED is flashing red, the device
detects a minor fault
5. When the LED is red, the device detects
an unrecoverable fault
6. When the LED is flashing red/green, the
device is self testing
For the Network Status LED:
1. When the LED is off, the network is nonpowered/not online
2. When the LED is flashing green, the
network is online but not connected
3. When the LED is green, the network is
online and connected
4. When the LED is flashing red, the
network has a connection time-out
5. When the LED is red, the network has a
critical link failure.

If the address is to be set to 3 and the Baud
rate to 500 k Baud, the dip switches should
be set as follow:
ON = 1
OFF = 0

Creation of an EDS file
In this example the DeviceNet network consists of a
FC 301 set up to address 3, a FC 302 set up to
address 4 and the Master (1756-DNB) set up to
address 0.
Start RS Networx and a new project.
Go online and browse the Network via RS Linx. If
RS Networx does not have an EDS (Electronic Data
Sheet) installed the Device will be shown as an
Unrecognized Device.
The EDS Wizard is started and click on Next.
Choose Create an EDS file and click on Next.
By Input/Output choose a type and a size. Note
that Strobed is not supported FC 301 and 302.
By the FC 300 series the EDS file can be created
from the Drive via RS Networx. It is also possible to
download the EDS file from
www.danfoss.com/BusinessAreas/DrivesSolutions
NOTE!:
The EDS file does not contain all
parameters but a selected, limited number
of parameters. Note that an EDS file needs
to be created for both FC 301 and 302.
To create an EDS file right click on the
"Unrecognized Device" and choose Register
Device.

Creation of an EDS file
Click on Next and the EDS file will start to be
created from the FC 300 Drive.

After the Parameter Objects that is used to create
the EDS file have been uploaded an Icon can be
linked to the FC 300 EDS file.
The FC 300 Icon can be downloaded from http://
www.danfoss.com/BusinessAreas/DrivesSolutions
After the EDS files for FC 301 and 302 have
been created you can browse the Network
again and the Drives will be shown.
NOTE!:
As the EDS files for FC 301 and 302 will
cover all motor and voltage sizes it is necessary to
upload the factory setting by the first
commissioning. This will secure that the correct
motor parameters are used in the EDS file.
Click on Network and Upload from Network.

Now all Devices on the DeviceNet will be
read.

Creation of an EDS file
Double click on one of the FC 300 and the
parameters can be changed and downloaded.
Parameter written from RS Networx via the EDS file
is from the factory stored in RAM. To store the data
in non-volatile memory parameter 10-31 Store Data
Values or parameter 10-33 Store Always can be
used.
