(1) ERR LED – error

Off: No power or device is in working condition

Red, single flash: Warning limit reached A bus error counter has reached or exceeded the limit for a warning

Red, flickering: LSS service running

Red, double flash: Error control event A „Guard-“ or „Heartbeat“ error has occurred

Red: Bus off (Fatal event) No communication (fatal error)

(2) RUN LED – operation

Off: No supply voltage

Green: Module in ‘operational’ status

Green, blinking: Module in ‘pre-operational’ status

Green, one flash: Module in ‘stopped’ status

Green, flickering: Autobaud Baud rate detection in progress

Lights up red: If the Run LED and Error LED light up red, this indicates a serious event that places the interface in an ex- caption state.           Contact the service team

Network topology:

• Linear bus, bus termination on both ends (121 Ohm), avoid stub cables

Medium and maximum bus length:

• When selecting cable, plug, and terminating resistors, ISO11898-2 and the CANopen recommendation CiA 303 “Cabling and connector pin assignment” must be observed.

Several stations:

• Max. 64 participants

Transmission speed:

• 1MBit/s, 500 kBit/s, 250 kBit/s, 125 kBit/s, 100 kBits/s, 50 kBits/s, 20 kBits/s, 10 kBits/s

Process data width:

• See section Setting the process data width of the bus module on page 28

Configuration Parameters
In some robot control systems, it may be necessary to state the configuration parameters described here so that the bus module can communicate with the robot.

Parameter	Value	Description
Vendor ID	0000 02C1hex (705dec)	Fronius International GmbH
Product Code	0000 0320hex (800dec)	Fronius FB Pro CANopen
Device name		Fronius-FB-Pro-CANopen

Setting the Bus Module Node Address

You can set the bus module node address as follows:

1. Using the DIP switch in the interface within the range 1 to 63
   •  All positions are set to the OFF position at the factory. In this case, the IP address must be set on the website of the welding machine
2. On the website of the welding machine within the range 1 to 126 (if all positions of the DIP switch are set to the OFF position)

Example for setting the node address of the bus module using the DIP switch in the interface:
Dip switch								Node address
8	7	6	5	4	3	2	1
–	–	OFF	OFF	OFF	OFF	OFF	ON	1
–	–	OFF	OFF	OFF	OFF	ON	OFF	2
–	–	OFF	OFF	OFF	OFF	ON	ON	3
–	–	ON	ON	ON	ON	ON	OFF	62
–	–	ON	ON	ON	ON	ON	ON	63

The node address is set with positions 1 to 6 of the dip switch. The configuration is carried out in binary format. This results in a configuration range of 1 to 63 in decimal format.

Setting the node address on the website of the welding machine:
Note down the IP address of the welding machine used:

1. On the welding machine control panel, select “Defaults” select “System”
2. On the welding machine control panel, select “Information” Note down the displayed IP address (example: 10.5.72.13)

Access the website of the welding machine in the internet browser: Connect the computer to the network of the welding machine

1. Enter the IP address of the welding machine in the search bar of the internet browser and confirm
2. Enter the standard user name (admin) and password (admin)

The website of the welding machine is displayed Set the bus module node address:

1. On the welding machine website, select the “RI FB PRO/i” tab
2. Enter the desired node address for the interface under “Module configuration”

For example: 2

1. Select “Set configuration” Select “Restart module”
2. The set node address is applied

Set the Process Data Width of the Bus Module
Setting the pro- cess data width of the bus module

• Note down the IP address of the welding machine used:

1. On the welding machine control panel, select “Defaults”
2. On the welding machine control panel, select “System”
3. On the welding machine control panel, select “Information”
4. Note down the displayed IP address (example: 10.5.72.13)

Open the website of the welding machine in the internet browser:

1. Connect the computer to the network of the welding machine
2. Enter the IP address of the welding machine in the search bar of the internet browser and confirm
3. Enter the standard user name (admin) and password (admin)
   • The website of the welding machine is displayed

Set the process data width of the bus module:

1. On the welding machine website, select the “RI FB PRO/i” tab
2. Under “Process data”, select the desired process data configuration
3. Select “Save”
   • The field bus connection is restarted and the configuration is applied

• Input and output signals

Data types
The following data types are used:

• UINT16 (Unsigned Integer)
  • The whole number in the range from 0 to 65535
• SINT16 (Signed Integer)
  • The whole number ranges from -32768 to 32767

Conversion examples:

• for a positive value (SINT16) e. g. desired wire speed x factor 12.3 m/min x 100 = 1230dec = 04CEhex
• for a negative value (SINT16) e.g. arc correction x factor 6.4 x 10 = -64dec = FFC0hex

Availability of input signals
The input signals listed below are available from firmware V2.0.0 of the RI FB PRO/I onwards.
