BAC-5051E Router Section 3: Setting up routing

Sec tion 3: Setti n g u p r o u ting

This section provides important guidelines for configuring a KMC BAC-5051E router for
BACnet routing. Review this information carefully for proper installation.

The BAC-5051E supports the following routing protocols.

l One MS/TP network

l One BACnet Ethernet

l Two IP networks that can be set up for any of the following protocols:

l Normal BACnet IP network routing

l BACnet broadcast management device with network and port address translation

l Foreign device registration with BACnet broadcast management devices (BBMD)

l PAD (packet assembling/disassembling) routing

Setting up routing can be performed either during initial configuration or after the router has
an IPaddress assigned and is installed in its permanent location. See Configuring the BAC-

5051E router on page 15 for initial configuration and log in procedures.

Network address translation

When using Network address translation, coordinate with the IT department to obtain a
public IPaddress and a port exception in the firewall.

Use public address Select to enable network address translation and port forwarding.

Public address The static public IP address supplied by the IT department.

Public port The public UDP port supplied by the IT department. For security, use a port that

is not in the typical range of BACnet ports.

The items in Table define the Broadcast Distribution Table (BDT) for the BBMD. Enter an IP
address, UDP port number, and IP subnet mask of each BBMD that is part of the
internetwork.

l If none of the BBMDs are using a public IP address, the BDT entries in every BBMD are

the same.

l If the BBMD uses a public IPaddress, the BDTs are different in every router. Each BDT

will use its own private IPaddress, port number, and subnet mask and the public
IPaddress, port number, and subnet mask for all of the other BBMDs on the
internetwork.

To add or delete entries, do the following:

l Adding entries—Click Add for additional entries.

l Deleting entries—Select sel and click Delete.

BACnet PAD routing

Either of the two IP ports can be configured for PAD (Packet Assembling and
Dissassembling) routing to a companion PAD router located on a different subnet. The
values on this page are assigned by the BACnet system engineer.

For the log in procedure, see the topic Initial setup on page 15.

2 Click Routing and then Configuration.

3 Select Enable for the port.

4 From the list box, choose PAD.

5 Set other properties as needed and then click Save.

Note: The router will restart. Foradditional changes, log in again.

A BACnet IP PAD router is a special type of router that connects two or more BACnet network
segments that are separated by at least one IP-only router. The PAD router monitors network
traffic for BACnet messages addressed to other subnets and then repackages the message
so that they can pass through IP routers, in effect forming a “tunnel” between the two
network segments. A companion PAD router unpacks and retransmits the message on the
remote BACnet network.

Enable Select to enable the network. The port block turns green when enabled.

Net Designates the BACnet network number for the port. Assign network numbers in the

range from 1 to 65534.

Port Assign a unique UDP port number to each of the enabled IP networks. The default port

Typically the MAC address fora router is zero (0).

Router Core properties page

The Router Core properties are general properties that apply to all routing protocols. The
properties consist of the Home Port selection and the Routing properties.

Home Port

Because the router is a BACnet device, it must be connected to one of the BACnet networks
by setting the Home Port property.

The home port is designated on a router port by the Home Port icon .

l

l The home port sets the network on which the router is connected. In operator

workstations, the router appears on the network designated as the home port network.

l The home port can be assigned only to an enabled network.

Using the MS/TP network reduces the APDU size and
significantly increases network traffic. KMCControls
recommends that one of the IP ports or the Ethernet port is
designated as the home port.

Routing properties

Route On Startup When selected, the router will immediately begin routing after a power

cycle or BACnet Cold start. This includes restarting the router on the Device properties page

on page 21. The router will also select the Enable Routing check box during the reset or

power up procedure.

Enable Routing When this check box is clear, routing on all ports is disabled but the router

remains an active device on the BACnet Internetwork. The MS/TP diagnostic and Routing
Status pages are still active. When routing is not enabled the background of Router Core is
gray. When routing is enabled the background is green. Routing can also be enabled or
disabled on the Routing Statuspage on page 37.

Use Learned Networks When selected, the router will attempt to learn the network number

being used on a port. This only works if there is at least one other router on the network that
responds to a BACnet What-Is-My-Network-Number message. If available the router
will use the learned network otherwise the router will use the configured network number.

The Routing Status list is a diagnostic display of all networks known to the router. Both direct
and remote networks are listed.

l Direct (or local) networks are connected directly to the router.

l Remote networks are on the other side of one or more remote routers. The path to a

remote network always includes at least one directly connected network.

Each of the columns lists information about local or remote networks.

Tip: If a directly connected network is shown to have a problem, the remote networks that

connect to it will also show problems. Correct directly connected network problems before
troubleshooting remote network problems.

Status The status of each network known to the router. See the table Route status

conditions for a description of each condition.

Net The columns under Net will change modes depending on the setting of Use Learned

Networks on the Routing Status page on page 37.

BAC-5051E Router Section 4: Diagnostics and status

If you encounter difficulty, click Refresh about every ten seconds to see how the Device
Status changes.

l If a MAC is red, start disconnecting devices from the networkand click Refresh as you

disconnect until the red goes away. This will help find the device that has the same
MAC address as the router.

l Gaps in the MAC addresses. MAC address gaps make the network less efficient

because devices will continually search for devices in the gap. Small gaps between
the router and the first device is okay, but you should try to eliminate gaps between
devices by changing MAC addresses.

l Gray can indicate several issues. This means communications at or near the gray

MAC address is intermittent. This can be caused by noise, loose wiring, and duplicate
MAC addresses. It could mean the end-of-line termination is not set properly. It could
mean a device has bad power and is resetting often. The problem is usually
associated with the first device that is shown gray.

l Known devices are not green. This is usually caused by bad wiring, bad grounding, or

not having the same baud-rate for the router and devices. To isolate the problem, start
splitting the network by physically disconnecting wires until devices begin
communicating.

The network metrics are useful for evaluating overall networkperformance.

Illustration 4–3 Diagnostic metrics

Interpreting the diagnostic data

Even the best designed and installed network will have minor or infrequent communications
issues. The following tips will help determine the significance of the networkmetric as well
as suggestions forimprovement.

Tx and Rx Frame Counts The actual number of frame counts depends on the baud rate and

number of network devices. The more connected devices, the slower the frame counts
grow. Unless the relative difference between the two counts is greater than 10%, the network
is generally okay. The reason is the router sends more messages than it receives is primarily
because of the small gap between its own MAC address and the next device.

46 Revision J

BAC-5051E Router Section 4: Diagnostics and status

Rx Frame Count greater than Tx Frame Count The greater the difference, the higher the

probability of the following conditions.

l One or more devices somewhere in BACnet internetwork is sending a lot of broadcast

messages.

l One or more devices on the router’s MS/TP network is sending a lot of network unicast

messages.

Typically a device is trying to find other devices that do not exist or are not communicating
properly and are repeatedly sending BACnet WHO-IS messages. Usually this is caused by a
Control Basic program or a Notification Class object recipient list referring to a device that
does not exist.

Rx Frame Count much less than Tx Count Will probably also see a device in a gray offline

status. It usually means devices are not communicating reliably either because of noise or
they because they are inundated with network messages and cannot keep up.

Tx Data Count This is the number of messages that contain actual point data. Most other

messages are just passing the token. In the previous example, the Data Count is only 0.1%
of the Tx Frame Count which just means the network is passing a small number of points or
trends. If this ratio is more than 30%, it may indicate a problem because it is likely that one or
more devices or workstation are gathering more data than is really needed. This can mean
the network will drop important messages.

Token Retry or Token Timeout This usually indicates a problem with the device next to the

router in the MAC chain. The cause could be noise specific to the device or general network
noise. This is not a problem unless this count is more than ten counts in a 24-hour period.

Rx PFM Count This indicates a problem between the router and the device just before it in

the MAC chain, usually the one at the end. A few counts in a 24-hour period is not unusual.

All other metrics Other metrics typically do not indicate a problem unless a value exceeds

ten counts in a 24-hour period. If you encounter issues, see the topic If you encounter

difficulty on page 12 to contact technical support.

Use the MS/TP Capture page to monitorand save the BACnet traffic on the MS/TP network.
The captured traffic can then be saved in a standard .pcap (Packet CAPture) file format.
Once saved, analyze the data with Wireshark or any other network analyzing program that
uses .pcap files. The router must be connected directly to the monitored MS/TP network.
This can be from either an existing router or a router temporarily connected as a service tool.

VAV balancing and configuration

Topics in this section are forcontrol technicians or engineers who will be balancing the
airflow in BAC-8000 or BAC-9000 series controllers. The BAC-5051E includes the following
features for balancing, configuring, and commanding airflow in a VAV controller.

l VAV balancing on page 55

l Configuring VAV setpoints on page 56

l Commanding and monitoring airflow on page 57

VAV balancing

The airflow balancing procedure described in this topic requires the following items.

l A flow hood or other accurate method to measure airflow.

l The engineering design specifications forthe minimum and maximum airflow

setpoints.

l A user name and password with permission to the VAV balancing feature in the

BAC-5051E.

Note: If the VAV unit is a heat only or cooling only unit, the airflow setpoints for the unused mode

must be set within the range of the mode in use. Failure to set the unused setpoints
correctly will result in unpredictable or erroneous air balancing settings.

Note: Starting the balancing procedure erases all previous airflow correction factors. The airflow

readings displayed on the VAV balancing page are the actual uncorrected airflow readings
as measured by the controller

1 Use an Internet browser to log in.

2 From the Advanced group click Balancing.

3 Enter a range of device instance values for the VAV units to be balanced.

4 Click Discover. Up to 50 devices will be added to the list.

5 Select a VAV unit from list of discovered units. The background of the selected unit

changes to yellow.

6 At the bottom of the page click the Balance tab.

7 Click Start Balancing. The controller commands the VAV controller to position the

damper for maximum airflow.

8 Wait forthe Actual Airflow value to stabilize.

9 With a flow hood, measure and note the actual airflow.

10 Enter the measured airflow in the Measured Max textbox. The controller then

commands the VAV controller to position the damper forminimum airflow.

11 Again, wait for the Actual Airflow value to stabilize.

12 With a flow hood, measure and note the actual airflow.

Revision J 55

Section 5: Advanced features KMC Controls, Inc.

13 Enter the measured airflow in the Measured Min textbox. The program in the controller

calculates new airflow constants and returns the VAV controller to normal operation.

Note: Fordual-duct VAV systems, both the primary and secondary airflows are displayed by the

application.

Configuring VAV setpoints

Airflow setpoints in BAC-8000 or BAC-9000 series controllers can be change from the
Configure tab.

1 Log in and discover the VAV units as described in the steps 1-5 in VAV balancing.

2 At the bottom of the page click the Configure tab.

The values shown are the actual values in the controllers. The values forDual
Minimum Flow and Secondary K Factor are active only if a dual-duct VAV controller is
selected.
