Product Overview

Use the BACnet MS/TP UBR-01 router to enable communication in a BACnet network. The router is the device sending messages through the network. The messages can be from master to slave or slave to master, and the router can trigger alarms and/or warnings if the communication is lost.

Network

Network Set-up

The system consists of 2 networks:

Ethernet network (shown as Network number 1-NW#1)
BACnet MS/TP network (shown as Network number 2-NW#2)

For the correct function of this network system, it is mandatory to follow the instructions on installation of the communication cables given in this user guide.

Cabling of the Networks

BACnet MS/TP Cabling (NW #2)

To ensure correct functionality of the BACnet MS/TP network, be sure to do the cabling correctly. Pay special attention to mounting of the cable shield and to termination of the network.

NOTICE

Never connect the shield to terminal 61 on the frequency converter.

Shielding of frequency converters connected to the same ground potential

Use an adequate equalizing cable to eliminate the risk of equalizing current running into the shield of the BACnet cables.
Mount the shield at the terminal marked Shld on the router.
On the frequency converters, connect the shield to the ground shield brackets.

Shielding of frequency converters without the same ground potential

If the frequency converters do not have the same ground potential, only connect the shield to ground in 1 location.
Expect a lower EMC performance.

Ethernet Cabling (NW #1)

_ NOTICE: _EMC INTERFERENCE

Use shielded cables for motor and control wiring, and separate cables for fieldbus communication, motor wiring, and brake resistor. Failure to isolate fieldbus communication, motor, and brake resistor cables can result in unintended behavior or reduced performance. Minimum 200 mm (7.9 in) clearance between power, motor, and control cables is required. For power sizes above 315 kW (450 hp), increase the minimum distance to 500 mm (20 in).

NOTICE

When the fieldbus cable crosses a motor cable or a brake resistor cable, ensure that the cables cross at an angle of 90°.

1	Ethernet cable
2	90° crossing

For the Ethernet, use standard shielded Cat5e patch cables. Maximum cable length is 100 m (328 ft).
An Ethernet switch distributes the packets to the participants on the Ethernet network. For industrial installation, only use industrial graded products as other products may cause faults and sporadic loss of communication.

Addressing and Setting up the Devices on the Networks

For proper function of the network, configure each device correctly.

Setting up the IP Address and Subnet Mask of the PC

On the PC, set up the IP address in the Internet Protocol Version 4 (TCP/IP) Properties configuration menu.

Open the Control panel window.
Select View network status and tasks.
Select Local Area Connection.
Select Properties.
Select Internet Protocol Version 4 (TCP/IPv 4).
Select Properties.
Select Use the following IP address.
Set the IP address to 192.168.0.xx, where xx must be a number not currently used on the network.
Set the subnet mask to 255.255.255.000.
Exit the windows to activate the new IP addresses.

Setting up the UBR-01

To route to and from the MS/TP network, configure the UBR-01 router via the router web page.
As factory setting, the UBR-01 has the IP address 192.168.0.1.

Enter the IP address 192.168.0.1 in the web browser address bar.
Press Enter.
- The main page of the router web page opens.
Consult the manual for the UBR-01 for login and password. Danfoss recommends to change the default login and password, since keeping the default is a security vulnerability.
Open the Device menu.
Enter the settings shown in Illustration 3.2.
Click Save.
Open the Ethernet menu.
Enter the settings shown in Illustration 3.3.
Click Save.
Open the MS/TP menu.
Enter the settings shown in Illustration 3.4.
Click Save.
Open the Activate menu.
Click Activate and restart to activate the settings, see Illustration 3.5.
The router restarts and the new settings become active, see Illustration 3.6.

Configuring the Frequency Converters

To enable the frequency converters to communicate over the embedded BACnet MS/TP network, set the parameters listed in Table 3.2 and Table 3.3.
For correct programming of the frequency converter, see the VLT® HVAC Drive FC 102 Programming Guide for details on setting up motor size, motor voltage, ramp times, and more.

Table 3.3 Required Communication Parameters and their Correct Settings, VACON® 100 HVAC

Parameter	Setting

1) To achieve a stable system, it is recommended that 3 write commands are sent within the timeout set in parameter 8-03 Control Timeout Time.

Testing the BACnet Settings in a Delta BMS System

For testing the settings in the UBR-01 router and in the frequency converters, a BMS tool is used for:

Scanning the network.
Find the BACnet devices.
Showing the device objects.

By selecting the frequency converter with device instance 1001, the BMS starts the discovery of the frequency converter objects and shows their present value. This proves the correct function of the UBR-01 and the frequency converters connected via BACnet.
