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

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

( L S B ) .

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.

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:

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.

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.

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 http:// 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 D e v i c e.

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.

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.
