Port Assign a unique UDP port number to each of the enabled IP networks. The default port number is 47808. Remote IP Enter the address of the remote BBMD. If network address translation (NAT) is used between the BAC-5051AE router and the BBMD, contact the network system administrator for the correct public IP address. Remote Port Enter the port number of the remote BBMD. If port address translation (PAT) is used between the BAC-5051AE router and the BBMD, contact the network system administrator for the correct public UDP port. Time To Live Sets the interval at which the router sends a registration message to the BBMD with which it is registered. The valid range is 1 to 65535 seconds.
BACnet Broadcast Management Device routing
For long-term network connections, KMC Controls recommends setting up a BACnet Broadcast Management Device (BBMD) configuration. Either of the two IP ports can be configured as a BBMD. When configuring an IP port as a BBMD, keep in mind the following rules.
l Configure only one BBMD for a single IP subnetwork. l Assign the same BACnet network number to all BBMDs on the internetwork. l The BBMD can accept registration from BACnet foreign devices or perform BBMD-to-
BBMD routing.
For more information about BBMDs, refer to the application guide All About BACnet Broadcast Management Devices (BBMD). For the log-in procedure, see the topic Initial setup on page 17. To set up the router as a BBMD, do the following:

Section 3: 30

KMC Controls, Inc.
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 subnetworks and then repackages the message so that it can pass through IP routers. In effect, this forms 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 number is 47808. Remote IP Enter the address of the remote PAD router. If network address translation (NAT) is used between the local router and the PAD router, contact the network system administrator for the correct public IP address. Remote Port Enter the port number of the remote PAD router. If port address translation (PAT) is used between the BAC-5051AE router and the PAD or BBMD, contact the network system administrator for the correct public IP address.

Router Core properties
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.

Revision A

Section 3:

KMC Controls, Inc.
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:
l is designated on a router port by the Home Port icon . l 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 can be assigned to an enabled network only.
Caution: 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 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 cleared, 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 the Router Core box is gray. When routing is enabled, the background is green. Routing can also be enabled or disabled on the Routing Status on page 35.

Section 3:
Use Learned Networks When selected, the router will attempt to learn the network number that is being using on a port. This works only in the event that there is at least one other router on the network that responds to a BACnet What-Is-My-Network-Number request. 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 on page 35.
Destination The Destination is always the network number the router is using.
l If Use Learned Networks is enabled, this is the learned network number. l If Use Learned Networks is not enabled, this is the network number entered for
the port on the Configuration page.
Configured (Use Learned Networks enabled) The network number that is configured for the port on the Configuration page. If this number is different than the Destination network, the network number displays in red. Discovered (Use Learned Networks not enabled) The learned network number at a port. If this network number is different than the network number on the Configuration page the number is in red and the status will be other than Active. Other networks are listed as N/A. Next Router A list of each network connected to the router's ports that will be used to route a message to the next router.

If you encounter difficulty, click Refresh about every 10 seconds to observe how the Device Status changes.
l If a MAC is red, start disconnecting devices from the network and 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 are accceptable, but 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.

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

The usual cause is a device trying to find other devices that do not exist or are not communicating properly and are repeatedly sending BACnet WHO-IS messages. It is typical for this to be 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 This may be accompanied by a device showing a gray, offline status. It usually means devices are not communicating reliably either because of noise or 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. This 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 workstations 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 there are more than 10 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 10 counts in a 24-hour period.

MS/TP Capture
Use the MS/TP Capture page to monitor and 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 the data is saved, it can be analyzed with Wireshark or any other network analysis program that uses .pcap files.
To use the MS/TP Capture feature, 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.

The Ping Results report is generated automatically after four ping attempts in a _ test or when the Stop button is clicked in a continuous ping test.

Using Ping data to optimize network perfomance
When using the ping feature to measure response times on MS/TP networks, it is important to understand that the MAC address and the Max Master configuration of devices have a noticeable effect. The following factors should be considered when interpreting the results of a ping test.
l The token cycle time increases as the number of devices on an MS/TP network increases. This leads to higher average response times.
l Even small amounts of ambient "useful" traffic (e.g., read-property or write-property messages) will have a significant effect on the time it takes for a token cycle to complete.
l MS/TP protocol dictates that missing devices (more specifically, unused MAC addresses) are polled periodically. Each poll takes a minimum of 20 milliseconds to complete. An unused range is called a "gap". Every 50 token passes, the device before a gap will start a process that polls one "missing address" in the gap each token cycle. When there are multiple gaps, it is possible for all the devices before the gaps to "line up" and start polling the same token cycle. A variation of this is when multiple devices overlap while conducting a poll.
l Max Info Frames, which is used to control how much a device can use a token, contributes to network traffic rates when it is set to values greater than "1". Values greater than "1" will slow down the token cycle in some situations.
The following are recommended practices for optimizing MS/TP network performance.
l Eliminate all gaps and set the Max Master correctly. This eliminates the polling process in normal situations.
l Keep the number of gaps small. The fewer the gaps, the less polling that occurs during a token cycle. For example, 10 gaps can equate to 200 milliseconds in a single token cycle.
l Keep the range of the gaps small. The greater the gap, the greater the number of cycles it takes to poll every MAC address within it. For example, a gap of 10 devices amounts to 200 milliseconds of processing time.
l The largest gap on many networks is between the highest MAC address used and the

MAX Master, which defaults to "127". Usually, this is done to allow for additional devices to be connected at a later time. However, setting the Max Master to a lower value can boost performance. For example, if the highest MAC used is 40, setting the MAX Master to 45 allows five devices to be added before having to reset the MAX Master. This also shortens the time it takes to poll. l Consider dividing the MS/TP network into smaller MS/TP networks. For best results, divide the devices so that traffic flow is roughly balanced and apply the four points above.

Section 5: Advanced features
VAV balancing and configuration
Topics in this section are for control technicians or engineers who will be balancing the airflow in BAC-8000 or BAC-9000 series controllers. The BAC-5051AE includes the following features for balancing, configuring, and commanding airflow in a VAV controller.
l VAV balancing on page 57 l Configuring VAV setpoints on page 59 l Commanding and monitoring airflow on page 60
The VAV Balancing features are accessible through the Balancing/AFMS/ZEC tab on the router served web pages and are active only when a valid VAV controller has been discovered.
VAV balancing
The airflow balancing procedure described in this topic requires the following items. l A flow hood or other accurate means to measure airflow l The engineering design specifications for the minimum and maximum airflow setpoints l A user name and password with permission to access the VAV balancing feature in the BAC-5051AE
Note: If the VAV unit is used for heat only or cooling only, 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/AFMS/ZEC. 3 Next to Instance Range, enter the device instance of the first SimplyVAV, followed in
the second text box by the device instance of the last SimplyVAV controller to be balanced.
Note: If a value is entered in the first (start) text box only before clicking Discover, the router software will automatically add 49 device instances to that number and display the result in the second (end) text box.
4 Click Discover. Up to 49 devices will be added to the list. VAV units can be identified as those with values shown under the Primary Coefficients heading in the list.

Note: For dual-duct VAV systems, both the primary and secondary correction coefficients display.
5 Select a VAV unit from the list of discovered devices. The background of the selected unit changes to yellow.
6 Click the Balance tab. 7 Click Start Balancing. The router commands the controller to start the balancing
function by positioning the damper for maximum airflow. 8 Wait for the value in Actual Airflow to stabilize. 9 With a flow hood, measure and note the airflow. 10 Enter the measured airflow in the Measured Max text box. The router then commands
the VAV controller to position the damper for minimum airflow. 11 Again, wait for the value in Actual Airflow to stabilize. 12 With a flow hood, measure and note the actual airflow. 13 Enter the measured airflow in the Measured Min text box. The program in the
controller calculates new airflow constants and returns the VAV controller to normal operation.
