6Library
There is one library that must be included in the Library Manager of the project to make it
work, BFICanOpen.
The library is automatically imported into the Library Repository of BCS Tools when extracting
the projectarchive file containing this Smart Engineering object.
It is also available on www.beijerelectronics.com and after download of the file it must be manually
installed into Library Repository and then added into a project.
Recommendation is to extract a projectarchive file and job is done.

7Nexto
Nexto Xpress
Nexto Xpress has one serial RS-485 port of screw terminals to be used for CanOpen marked as
“CAN” with CAN-H, CAN-L and ground. Normally the shield of the communication cable should
be connected to earth terminal. Termination is activated/deactivated in BCS Tools. Use cable
CAB155, see chapter 7.4,for BFI connection.
Figure 7.1 CanOpen connection of Nexto Xpress and terminal layout
NX-3008
NX-3008 has one CanOpen port. Screw terminals to be used are marked with H, L and Shield.
Connect the shield of the communication cable to terminal “Shield”.
Use cable CAB155, see chapter 7.3, for BFI connection.
Figure 7.2 CanOpen connection of Nexto BCS-NX3008. Right picture is the zoomed
CanOpen terminals.

to BFI-P2/E3.
Figure 7.3 Drawing of CAB155 from Nexto PLC to BFI by CanOpen
Termination of the RS-485 bus in Nexto
A RS485 network should normally be terminated with 2 pieces of 120-ohm resistor, one in each end
of the physical network.
In Nexto PLC:s the termination is activated in BCS Tools, see below figure 7.4.
Termination of BFI is solved by an option, a RJ45 connector with built-in resistor, see chapter 8.5.

8CanOpen port and digital signals to BFI
Hardware signals to BFI-E3
BFI-E3 requires one digital signal to be run by communication.
Figure 8.1 Hardware signals required to run BFI-E3 by CanOpen.
Running can also be a combination of communication instructions and analog/digital signal.
See User Manual or contact Beijer Electronics support.
Hardware signals to BFI-P2 and BFI-H3
BFI-P2/H3 require a software enable, 24VDC, on DI1, terminal 2.
They also have 2 STO-inputs. If the STO-inputs are not to be used, they need to be bridged as
picture below.
Figure 8.2 Hardware signals required to run BFI-P2 and BFI-H3 by CanOpen.
Running can also be a combination of communication instructions and analog/digital signal.
See User Manual or contact Beijer Electronics support.

RJ-45 connector in BFI IP20, IP55 and IP66
CanOpen port in BFI depends on model. It has either one or two RJ45 connector.
-All BFI IP66 have two RJ45 connectors for incoming and outgoing CanOpen cabling.
-All BFI IP20 and IP55 have one RJ45 for CanOpen connection.
Red marked area shows location of the RJ45 supporting Modbus RTU, CanOpen and internal bus.

Note! Do NOT mix the serials port with the Ethernet ports in BFI-E3 IP66 with built-in ethernet
or option boards intended for ethernet.
Termination of the BFI
Termination of BFI is made by an RJ45 contact with resistors included for both CanOpen and
Modbus, OPT-2-J45SP-BFI. If BFI only has one RJ45 port also a splitter is required, OPT-2-
RJTRM-BFI.

9System setup with Smart Engineering object
There are 2 different PLC-programs, *.projectarchive files, depending on PLC type in use.
The same iX project supports all these PLC-projects.
-Nexto Xpress 300
-Nexto Xpress 340 with Webvisu
The PLC-project supports one BFI-E3 with station number 1 and one BFI-P2 with station
number 2. Controllers can be Nexto Xpress or NX-3008.
Fastest way to set up a system:
1. Set up of Station number address and communication speed in each BFI.
All parameters can be set on the display of BFI, with PC software BFI-Tools with BFI-
Tools Mobile or use BFI-Smartstick. See chapter 10.1.
2. Every BFI needs to have 24VDC on terminal 2, software enable.
Either control terminal 2 from a PLC or switch or put a jumper between terminal 1 and 2.
See chapter 8.1 or 8.2.
3. For BFI-P2: STO inputs need to be properly connected.
BFI-E3 has no STO, Safe Torque Inputs. See chapter 8.2.
4. Connect the CanOpen communication cable from Nexto Xpress to RJ-45 port of
BFI.
See chapter 7.5.
5. Termination of network
Make sure termination of the communication network is correct. See chapter 7.4and 8.5
6. Make sure using correct software versions of BCS Tools and iX Developer
7. Set up the IP address of Nexto Xpress or NX-3008.
Default is 192.168.15.1. See chapter 12.7.
8. Download the Smart Engineering object, PLC-project, to Beijer controller.
Chose the project archive file corresponding to the Beijer controller being used. Adjust the
device to fit the used hardware.
9. Check that station number of each BFI correspond with PLC-program and eds file.
Node-Id 1 is a BFI-E3 and Node-Id 2 is BFI-P2 Size2_3.

10 Settings in BFI
Parameter settings for BFI-P2/E3
Set following parameters in BFI-E3
- P.12 = 7: CANopen control with Acceleration and Deceleration time in parameter P-03 and P-04.
- P.12 = 8: CANopen control with Acceleration and Deceleration time sent by CANopen.
- P-14 = 201: Make all parameters available.
- P-25 = 13: Analog Output of BFI-E3 controlled by bus.
- P-36 =Node ID number. Default=1.
- P-36 = 500 Kbits/sec. We recommend to not use 500 kbit/sec.
Set following parameters in BFI-P2
- P1-12 = 6 for CANopen control.
- P1-14 = 201 to make all parameters available.
- P5-01 = Node ID number. Default=1.
- P5-02 = 500 Kbits/sec. We recommend using 500 kbit/sec.
- P5-07 = Disable=> Acceleration and Deceleration time set in parameter P1-03 and P1-04
- P5-07 = Enable=> Acceleration and Deceleration time ramp sent by bus.
- P9-33 = 2: Analog Output1 on terminal 8 of BFI-P2 will be controllable from PLC.
Communication timeout
The reaction at communication interruption between CanOpen master and BFI is set in BCS
Tools. It is on individual bases for each BFI.
If the BFI is to trip at communication is interrupted, set as below:
NodeID of Guarded Node=127 (=CANopen Master) and Consumer Time means the BFI
needs to have a message from the Master within this time frame. 300 ms in example below
means trip of BFI if no message within 300 milliseconds.
The time settings in P-36 of BFI-E3 and P5-05 in BFI-P2 has no effect.
If the BFI is to continue at communication interruption, set as below:
