1. GENERAL INFO

Instead of sending and receiving information to and from frequency converters through I/O, you can
connect them to a fieldbus.

Vacon NX frequency converters can be connected to the RS-485 bus using a fieldbus board. The
converter can then be controlled, monitored and programmed from the host system.

BACnet is also known by names Direct Digital Control Systems and Building Management Systems.
BACnet technology is used mostly in building automation, lightning control, air conditioning and in
heating automation. The protocol is an upper level net protocol suitable for large building
automation projects.

BACnet stands for

Building Automation and Control Network. BACnet is a true non-propriatery open

protocol communication standard conceived by a consortium of building management, system users

and manufacturers.

If you purchase your BACnet option board separately, please note that it shall be installed in

slot E

on the control board of the frequency converter.

WARNING!

Internal components and circuit boards are at high potential when the frequency
converter is connected to the power source. This voltage is extremely dangerous
and may cause death or severe injury if you come into contact with it.

3. BACNET FIELDBUS BOARD LAYOUT AND CONNECTIONS

Vacon BACnet option board is connected to the fieldbus through a 5-pin pluggable bus connector.
The communication with the control board of the frequency converter takes place through the
standard Vacon Interface Board Connector.

4. GROUNDING CABLE SHIELD

4.1 Grounding by clamping the cable to the converter frame (recommended)

This manner of grounding is the most effective and especially recommended when the distances
between the devices are relatively short or if the device is the last device on

the net.

Note: Normally, the option board has already been installed in slot D or slot E of the control board. It

is not necessary to detach the whole board for the grounding of the bus cable shield. Just detach the
terminal block.

1 Strip about 5 cm of the cable and cut off the grey cable shield.

Remember to do this for both bus cables (except for the last device). See pictures below.

2 Leave no more than 1 cm of the cable outside the terminal block and strip the data cables

at about 0.5 cm to fit in the terminals. See pictures below.
Note: Do this for both bus cables.

3 Insert the data cables of both cables into terminals #3 (Line B) and #4 (Line A).
4 Strip the cable at such a distance from the terminal that you can fix it to the frame with the

grounding clamp. See pictures below:

Figure 4-3.

4.2 Grounding only one point on the net

In this manner of grounding, the shield is connected to ground only at the last device on the net in
the same way as described in chapter 4.1. Other devices of the net just pass the shield.
We recommend you to use an Abico connector to fit the shields into the terminal.

1. Strip about 5 cm of the cable and cut off the grey cable shield. Remember to do this for
both bus cables (except for the last device).

2. Leave no more than 1 cm of the cable outside the terminal block and strip the data cable
at about 0.5 cm to fit in the terminals. See Figure 4-4.

Figure 4-5.

Note! Do this for both cables.

4.3 Bus terminal resistors

Figure 4-8. Using jumper X4 to set the bus termination.

If Vacon is the last device of the fieldbus line the bus termination must be set. Use jumper X4 (ON

position). See Figure 4-7.

Note: Jumper X1 is only used when D9 type connector is assembled (Not used with BACnet protocol)

4.4 Bus Biasing

Bus biasing is required to ensure faultless communication between devices at RS-485 bus. Bus
biasing makes sure that the bus state is at proper potential when no device is transmitting. Without
biasing, faulty messages can be detected when the bus is in idle state. RS-485 bus state should be
neather +0,200..+7V or –0,200..-7V. Illegal bus state is <200mV..-200mV.

Number of nodes Bias resistance
2-5 1.8 kohm
5-10 2.7 kohm
11-20 12 kohm
21-30 18 kohm

31-40

27 kohm

7. COMMISSIONING

READ FIRST CHAPTER 8 'COMMISSIONING' IN VACON NX USER'S MANUAL (Document nr. ud00701,
please visit http://www.vacon.com/Default.aspx?id=450403&FileView=462792).

Note! You must select Fieldbus as the active control place, if you wish to control the frequency
converter through fieldbus. See Vacon NX User’s Manual, Chapter 7.3.3.1.

7.1 Fieldbus board parameters

The Vacon BACnet board is commissioned with the control keypad by giving values to appropriate
parameters in menu

M7 (for locating the expander board menu see Vacon NX User's Manual,

Chapter 7).

7.2 Expander board menu (M7)

The

Expander board menu

makes it possible for the user 1) to see what expander boards are

connected to the control board and 2) to reach and edit the parameters associated with the expander
board.

Enter the following menu level

(G#) with the

Menu button right

. At this level, you can browse

through slots A to E with the

Browser buttons

to see what expander boards are connected. On the

lowermost line of the display you also see the number of parameter groups associated with the
board.

If you still press the

Menu button right

once you will reach the parameter group level where there

are two groups: Editable parameters and Monitored values. A further press on the

Menu button right

takes you to either of these groups.

7.3 BACnet parameters

To commission the RS-485 board, enter the level P7.5.1.# from the

Parameters

group (G7.5.1). Give

desired values to all RS-485 parameters (see Figure 7-1 and Table 7-1).

7.3.1

MS/TP MAC address (P7.x.1.1)

The parameters of every device must be set before connecting to the bus. Especially the
parameters

MAC Address

and

Baud Rate

must be the same as in the master configuration.

The first parameter, MAC (Medium Access Control) address, must be unique on the network
to which it is connected. The same MAC address may be used on a device on another network
within the internetwork.
Addresses 128-254 are reserved for slaves. Addresses 1-127 are valid for both masters
and slaves. The portion of the address space that is actually used for masters in a particular
installation is determined by the value of the Max_Master property of the Device object.
It is recommended that MAC address 0 be reserved for use by the MS/TP router and 255 is
reserved for broadcasts.

7.3.2

Baud rate (P7.x.1.2)

Select the communication speed for the network. Default value is 9600 baud. 0 (– Auto)
means that automatic baud rate detection is used. The used Baudrate is shown in monitor

menu.

7.3.3

Instance number (P7.x.1.3)

The Device Object's Instance number must be unique across the entire BACnet internetwork
because it is used to uniquely identify the BACnet devices. It may be used to conveniently
identify the BACnet device from other devices during installation.
If 0 (default) is selected, the Device Instance number is read from Drive. This unique number
is then shown in Monitor menu. If any other value than zero is selected, the value is used as
Device Object’s Instance number. The actual value is shown in monitor menu.

7.3.4

Communication time-out

BACnet board initiates a communication error if the communication is broken for as long as
defined by the parameter Communication time-out. Communication time-out is disabled
when the parameter is given the value 0. The step for setting the time-out time is 10 seconds.

Fieldbus fault -The board has lost all contact with other

devices on the network.

- Duplicate MAC ID (Bad Frames in
“Comm. status” is incremented every
time a frame is received from a device
with the same MAC id on the same

segment.)

Check the installation.
If installation is correct contact the
nearest Vacon distributor.
Check that MAC ID is unique.

54

Slot fault Defective option board or slot. Check the board and slot.

Contact the nearest Vacon distributor.
