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.

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.

Configuring the FC 300 with RS Networx
Double click on the 1756-DNB Scanner.
Click on Scanlist and add the two Devices
from Available Devices to the Scanlist.
Click on one of the FC 300 and on Edit I/O
Parameters.
The Polled input/output byte size needs to match
the actual instance type in parameter 10-10
Process Data Type Selection according to the table
below.
Click on Input and if you click on AutoMap
the I/O area of the FC 300 Devices will be
added to the first free area, here I 0.0.
Note that the I/O area of the Control logix Scanner
is organised as 32 bits (double word). This may vary
by other Scanner types.
This means that the FC 301 (address 3) Status word
will be read from the I/O area I:0.0 to I:0.15 and the
Main Actual Value from I:0.16 to I:0.32.
Parameter Polled size Polled size
10-10 input output
Instance 20/70 4 bytes 4 bytes
Instance 21/71 4 bytes 4 bytes
Instance 100/150 4 bytes 4 bytes
Instance 101/151 8 bytes 8 bytes
In this example FC 301 (address 3) is setup to Polled
I/O with 4 bytes using instance 100/150 and FC 302
(address 4) is setup to Polled I/O with 8 bytes using
instance 101/151.
The last four bytes of Instance 101/151 can be
configured in parameter 10-11 Process Data Write
and 10-12 Process Data Read.
Do the same with the Output to map Control word
and reference.

FC 300 DeviceNet and Allen Bradley Control logix 5550
Configuring the FC 300 with RS Networx
Auto-Device Replacement, or ADR, is a feature that
automatic replaces a failed device on a DeviceNet
network and returns it to the original setup without
having to use a software tool. It consists of two
features:
z Configuration Recovery, CR.
With this feature the Scanner will download the stored configuration (EDS file) to
the FC 300 before it begins to exchange
I/O data with that device. Notice this will
happen by each power up of the Master,
so this will expand the power up time.
z Auto Address Recovery, AAR.
With this feature the scanner (master)
will change the device node address from
63 (the default address) to the original
address.
Example: The connection between the
Scanner and FC 301 at node address #3
is broken and the FC 301 needs to be
replaced. In this situation the Scanner
will continually query for a new FC 301 at
node address #63. When a new FC 301 is
power up with the factory settings and if
the Electronic Key of the device that the
scanner lost at node address #3
matches, it will change the node address
from #63 to #3.
After Auto Address Recovery the EDS file
will be downloaded the node address #3.
The FC 300 can now be seen as an available device
for ADR.
Click on each node and click on „Load Device
Config“. Click also on Configuration Recovery and
Auto-Address Recovery by ADR Settings if these
functions are require.
Click on ADR to set up the ADR menu.
