CANopen OPTION CARD FOR VLINX FIELDBUS GATEWAY

 CONFIGURED USING VLINX FIELDBUS GATEWAY MANAGER

 DIGITALLY ISOLATED CANopen PORT CAPABLE OF

COMMUNICATING WITH ANY CANopen DEVICE

 EASY INSTALLATION

VFG9000-CAN-1012qsg

GENERAL DESCRIPTION

The Vlinx Fieldbus Gateway contains a proprietary expansion port which
provides a high speed, parallel architecture that extends the functionality and
flexibility of the platform. This approach allows these products to evolve
concurrently with the latest advances in communications and standards, without
sacrificing performance. This high bandwidth channel has significantly greater
throughput when compared to the traditional (external) serial gateway approach.

The VFG9000-CAN option card adds a CANopen communication port to the
series. This isolated card protects user equipment from potentially harmful
ground loops while providing the ability to communicate to any high speed
CANopen device. The VFG9000-CAN option card has a termination resistor
built-in, which is selectable via a jumper setting.

The VFG9000-CAN communication card is easily installed by removing the
blank expansion port cover of your Fieldbus Gateway, and plugging the
VFG9000-CAN card into the expansion port. Configuration is simple using
B&B Electronics’ free Fieldbus Gateway Manager software.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.

Do not use the controller to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially harmful to
persons or equipment in the event of a fault to the controller.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

INSTALLING THE VFG9000-CAN OPTION CARD

1. Remove power from the unit

2. Insert a flat-bladed screwdriver into the slot at the top of the expansion port
cover. Gently apply pressure on the screwdriver in an upward direction until
the expansion port cover disengages from the unit as shown in Figure 1.

3. Verify that the option card knobs are in the “unlocked” position as shown in
Figure 2.

4. Carefully insert the option card into the expansion port opening while
aligning the card-edge connector on the option card with the main board's
header, as shown in Figure 3. Once aligned, gently press on the front of the
card until it is flush with the front of the case.

5. Turn the option card knobs to the locked position as shown in Figure 4.

Caution: The expansion and main circuit boards contain static
sensitive components. Before handling the cards, discharge static
charges from your body by touching a grounded bare metal object.
Ideally, handle the cards at a static controlled clean workstation.
Also, handle the cards by the edges only. Dirt, oil, or other
contaminants that may contact the cards can adversely affect circuit
operation.

Warning: Risk of Danger: Be sure to remove all power before

removing the expansion port cover

COMMUNICATING WITH THE VFG9000-CAN
OPTION CARD

CONFIGURING A VFG9000-CAN OPTION CARD

The VFG9000-CAN is configured using Fieldbus Gateway Manager
software. Updates to the software for new features and drivers are posted on the
website as they become available. By configuring the VFG9000-CAN using the
latest version of the software, you are assured that your unit has the most up-to­date feature set. The software can configure the VFG9000-CAN through the
RS232 PGM port, USB port, Ethernet port, or CompactFlash socket on your
Fieldbus Gateway. Additional information can be found in your Fieldbus
Gateway hardware bulletin and the Fieldbus Gateway Manager user manual.

CANopen PORT PROTOCOLS

The VFG9000-CAN option card has one CANopen port. This port may be
configured for various CANopen protocols. Check www.bb-elec.com for
currently supported protocols.

CAN+

Position 4 of the pluggable connector provides the CAN+ bus line (active

high). This terminal is isolated from the Fieldbus Gateway.

V+ (OPTIONAL 24 VDC)

Position 5 of the pluggable connector is provided for optional 24 VDC
connections. This position is available only to tie 24 VDC wires together. The
VFG9000-CAN card neither provides 24 VDC power nor uses 24 VDC power
through this connection. The V+ position is not connected to any circuitry
internal to the VFG9000-CAN option card or Fieldbus Gateway.

LED

The LED will illuminate green when the VFG9000-CAN option card
establishes communication with other CANopen devices (RUN). The LED will
illuminate red if no communications have been established with other CANopen
devices (ERROR).

TROUBLESHOOTING YOUR VFG9000-CAN OPTION CARD

If for any reason you have trouble operating, connecting, or simply have
questions concerning your new VFG9000-CAN option card, contact B&B
Electronics’ technical support. For contact information, refer to the back page
of this bulletin for phone and fax numbers.

TERMINATION RESISTOR

An onboard termination resistor is selectable via a jumper setting. The
termination resistor is rated for 124Ω at 1W. If a different termination resistance
is desired, choose the jumper setting for no termination resistor and connect
your own termination resistor between positions 2 and 4 of the five position
connector.

GND

Position 1 of the pluggable connector provides a CAN ground connection.
This terminal is isolated from the Fieldbus Gateway.

CAN-

Position 2 of the pluggable connector provides the CAN- bus line (active
low). This terminal is isolated from the Fieldbus Gateway.

SHLD (OPTIONAL CAN SHIELD)

Position 3 of the pluggable connector is provided for optional shield
connections. This position is available only to tie shield wires together or to
earth ground. There is no internal connection to earth ground. The SHLD
position is not connected to any circuitry internal to the VFG9000-CAN option
card or Fieldbus Gateway.
