INTEGRATION OVER BACNET MS/TP
In general, all wiring and installation techniques should follow the Open Controller Network Wiring Guide, Catalog No. 11808-461-01, instructions. However, please note the following details and exceptions that MUST be observed on networks containing SystemVu controllers.
Communication Cable and Wire
The communication cable and wire used in networking can greatly impact the performance of the network communication over that wire. Follow the details shown in Table 1 as best practice with wiring on MS/TP BACnet networks.
POSSIBLE COMMUNICAITONS FAILURE · Do not allow more than 0.125 inch (0.3 cm) bare
communication wire to protrude. See Fig. 5. · If bare communication wire contacts the cable’s foil
shield, shield wire, or a metal surface other than the terminal block, communications may fail. · Best practice is to tape wires up to the BAS plug to prevent contact with any metal. See Fig. 6.

TO WIRE THE COMMUNICATION CABLE
1. Partially cut, then bend and pull off 1 in. of the outer jacket of the cable(s). Do not nick the inner insulation. See Fig. 4.
2. Strip about 0.25 in. (0.6 cm) of the inner insulation from each wire. See Fig. 4.
3. If wiring two cables to the controller, twist together the shield wires from both cables.
4. Insert the wires into the appropriate terminal block (see Fig. 7 and 8 on page 6). Take care the drain wire is electrically isolated, where exposed.
5. All connections should be made with power turned off to all the network devices and SystemVu controllers.
正确 不正确 不正确
Fig. 5 — Correct vs. Incorrect Connections
Fig. 6 — Correct Connections — Best Practice NOTE: Do not ground the shield to earth ground or to the controller’s power ground. The PROT485 and the individual controllers allow the shield to float a limited amount so that there are no ground loops. If the voltage on the shield becomes too great, relative to the earth ground, then the excess voltage is bled off with protective devices on the PROT485 or on the controllers.

网络设计
With a locally biased controllers, per RS-485 standards, the maximum recommended number of nodes per segment/trunk depends on the baud rate of the network.
38,400 baud = maximum of 15 nodes and a router
76,800 baud = maximum of 31 nodes and a router
Please note that the SystemVu controller is a LOCALLY biased device as opposed to the OPEN product line which are NETWORK biased devices.
Therefore, the BT485 device is NOT used in a SystemVu only network and it is NOT used in a network composed of SystemVu and OPEN products together.
In addition, the end of line / end of net switches on OPEN products and routers are NOT used with SystemVu controllers on the bus. Since these switches may also add network biasing, they are not needed with a locally biased product. There are no end of line switches on SystemVu products.
NOTE: Note: A 120 Ohm Resistor MUST be used to terminate the bus at both ends in accordance with standard RS-485 requirements. The TERM485 device is recommended.
With careful wiring practices, one network segment can use up to 4,000 feet of network wire. However, best results are achieved when total wire length on a trunk is limited to 2000 feet.
In addition, the use of a repeater (the REP485 is the only currently allowed repeater) for network segments over 2000 feet of wire is encouraged, but not mandatory. Please refer to the Open Controller Network Wiring Guide for detailed REP485 installation instructions. Note that the REP485 counts as a node on both network segments it connects.
The use of the PROT485 device is highly recommended for all network segments with SystemVu controllers. Please refer to the Open Controller Network Wiring Guide for detailed PROT485 installation instructions.
Finally, please note that rigorous adherence to the wiring hygiene recommendations here and in the Open Controller Network Wiring Guide will produce the best network results.
SystemVu controllers should have the BAS wiring connected to plus, minus, and the shield wire to COM as shown in Fig. 7 and 8.
网络拓扑结构
All BACnet MS/TP networks should be wired in a true “daisychain” configuration.
BACnet MS/TP network best practices dictate that the MAC addressing of the nodes on the network should be sequential with the physical location of the units. For example, if the router is the first node on the network, it should have the lowest MAC address. The next unit on the daisy-chain should have a MAC address one number higher, etc.
接地和极性
A quality earth ground is essential to ensure proper unit operation AND proper BAS communication function.
There is not one standard ground resistance threshold that is recognized by all agencies.
However, the NFPA (National Fire Protection Association) and IEEE have recommended a ground resistance value of 5.0 ohms or less. The NEC has stated: “Make sure that system impedance to ground is less than 25 ohms specified in NEC 250.56.” In facilities with sensitive equipment, it should be 5.0 ohms or less. The telecommunications industry has often used 5.0 ohms or less as their value for grounding and bonding.
If you suspect you may have grounding issues at a facility, specialized earth grounding testers are used by qualified electrical contractors to test for correct grounding.
In addition, control power polarity should be maintained throughout the BAS network AND communication wiring polarity should be maintained as well. Per the recommendations in the Open Controller Network Wiring Guide regarding the PROT485, shield wires should NOT be grounded to any earth ground or to the controller’s power ground. The PROT485 and the individual controllers allow the shield to float a limited amount so that there are no ground loops. If the voltage on the shield becomes too great relative to the earth ground, then the excess voltage is bled off with protective devices on the PROT485 or on the controllers.
Packet Segmentation
The BACnet stack used with the SystemVu product does NOT currently support packet segmentation.
Segmentation should be turned OFF on the third-party devices.
Please be aware that the segmentation feature is NOT required for current BTL (BACnet Testing Laboratories) certification.
i-Vu Integration Tips Source Files and Version Variations
The current SystemVu products are compatible with i-Vu versions 7.0 and later. Older versions of i-Vu software may not work correctly with current SystemVu products.
All current i-Vu patches must be installed when connecting to SystemVu products. These may be obtained from the “Controls Download” section of HVACPartners or from the Carrier Controls website software section.
It is often necessary to manually add the SystemVu source files to the i-Vu server and place into the appropriate folder.
Please note that the source files are located on HVACPartners (Currently located under the SUPPORT TAB > POST SALE SUPPORT > SERVICE SOFTWARE).
COV (Change of Value) and Third-Party Routers
The COV feature in BACnet MS/TP is used extensively by some third-party vendors.
However, SystemVu only supports a limited number of COV points. Router requests for COV points that are not supported by the SystemVu controller can lead to network errors and poor network performance.
Turning the COV function OFF in the third-party devices can be a helpful tool when troubleshooting network traffic issues.
Certain job sites or customers may require that the COV feature be used.
If this is the case, Table 2 shows the exact COV points supported by the SystemVu controller.

BACnet Point Integration with Third Party Routers
With certain third-party vendors the automated BACnet point identification feature is either very slow or will not work with SystemVu units due to the high number of available BACnet points on a standard SystemVu unit.
If this occurs, it is advisable to provide a specific point list by point name / BACnet identifier to the third-party vendor. This will allow the vendor to discover the points needed for the job much more quickly.
Of course, this will be job specific depending on unit type, controls contractor, engineer’s sequence of operation, etc.
See Table 3 for an example of an abbreviated point list.

APDU Timing, Polling Rates, etc. with Third-Party Routers
It is not uncommon to need to adjust a number of router settings that vary significantly from job to job.
Unfortunately, there are not “set in stone” values that work on every job.
Please be aware that some of these values include APDU timeout rates, polling rates, and NPDU timeout rates.
In general, longer polling rates for BACnet objects are to be preferred (polling too frequently increases bus traffic). Polling/refresh rates should not be set below every 30 seconds. It is best to keep the polling/refresh rates between 1 and 5 minutes. In general, the recommendations in OAPN022 application tip regarding read and write rates should be observed.
It is a best practice to set timeout rates such as APDU timeout rates at the highest timeout rate of any device on the network. Many devices default at 3000 milliseconds. SystemVu is defaulted to 6000ms and cannot be changed. When applying SystemVu controls on a BACnet bus with other devices, all devices should be set to match SystemVu at 6000ms.
The SystemVu APDU segment length is fixed at 480 bytes. Since the BACnet stack used for SystemVu controllers does NOT support packet segmentation, some third-party routers may need have the APDU segment size or RPM “chunking” or “bin packing” algorithms manually adjusted to properly work with features such as Read Property Multiples.
Frame Rates and Third-Party Routers
Many third-party vendors default their router “MS/TP Max Info Frames” value to “100”. This is too high for SystemVu nodes a value of “20” will provide a more stable network.
All legacy production SystemVu software versions have the “Max Info Frames” value default to “10”. Older versions defaulted to “1” which can cause network issues. If a network with older SystemVu units is experiencing issues, upgrading to current production software is recommended.
The current A2L production units have adjustable frame rates and max master values.
SYSTEMVU INTEGRATION WITH SYSTEM TOUCH OVER MS/TP PORT
What is System Touch
The System Touch is a touchscreen device with a color LCD display that provides as a user interface to controllers on a single BACnet network. The System Touch has built-in temperature and humidity sensors. These values can be read by controllers to control equipment. You can also wire an external thermistor to the System Touch and use its value instead of the built-in temperature sensor’s value.

SYSTEMVU INTEGRATION WITH ZS SENSOR OVER RNET
ZS 传感器
ZS Sensors are thermistor-based temperature sensors that can optionally sense humidity, motion, and either CO2 or VOC. ZS Sensors communicate with the HVAC system through the Rnet.
ZS Sensor functionality is determined by:
· The sensor models
· The sensor’s sensing capabilities (temperature, humidity, motion, CO2, VOC)
· The control program that runs the associated equipment ZS Sensors are wired to the Rnet port on SystemVu controllers. For more information about Zone Sensor, refer to the below manuals documents available on HVACPartners or the Carrier Controls Website. · ZS Sensors User Guide · ZS Sensors Installation Guide
Steps to Connect SystemVu and ZS Sensor Over Rnet Port
Each ZS Sensor connected via the Rnet port must have a unique address, but addresses do not have to be sequential. Open the hinged cover on the sensor enclosure, and then use the DIP switches to set an address from 0 to 14. (1 is factory default.) Each DIP switch has the value shown in the Fig. 15 below. Turn on as many DIP switches as you need so that their total value equals the address.

绿色状态 LED
The SystemVu controller has one Green LED. This LED (indicates Local Equipment Network) should always be blinking whenever power is ON. If LEN LED is not blinking, check LEN connection for potential communication errors (MBB J15, J16, J17, and J2 on the Display).
Yellow Status LED
Yellow LED is used to indicates Building Automated Systems (BAS) communication activity. The LED will blink when the MBB transmits a message on the BACnet bus.
TROUBLESHOOTING BACNET MS/TP
BACnet MS/TP Configurations
SystemVu can use the BACnet MS/TP protocol for communications. This section in the document contains Carrier’s recommendations for configuring and wiring an MS/TP network that will provide the best network performance with Carrier controllers. However, Carrier controllers will work on any BACnet-compliant MS/TP network. Controllers can communicate on an MS/TP network at 9600 bps, 19.2 kbps, 38.4 kbps, 57.6 kbps, 76.8 kbps, or 115.2 kbps.
For configuring SystemVu BACnet Baud Rate, navigate to the below menu in user interface and select the Baud Rate.
UI Menu > SETTINGS / NETWORK SETTINGS / BACNET
Please note that source files are needed for proper detection of SystemVu units by an i-Vu system. Source files are included in cumulative patches OR can be manually imported into i-Vu. Source files and the process for importing them are located on HVACPartners.
i-Vu MODSTAT
For additional debugging on iVu systems use the MODSTAT command in i-Vu which when requested will trigger the System Software Information along with BACnet Firmware version as shown in the below Images.
1. Select the Controller listed under Router (see Fig. 21).
2. Right click and select the MODSTAT (Module Status) command. (see Fig. 22). A new Pop up window will come with the list of Controller Software and BACnet firmware versions as shown in Fig. 23.
Fig. 22 — iVu MODSTAT Command Screenshot
Fig. 23 — iVu Firmware Versions Screenshot
Controller Addressing
Each SystemVu controller on the MS/TP network must have a unique BACnet MS/TP MAC address, which is set by the User Interface Menu. Valid addresses are 1-99. BACnet MS/TP network best practices dictate that the MAC addressing of the nodes on the network should be sequential with the physical location of the units. I.E. If the router is the first node on the network, it should have the lowest MAC address. The next unit on the daisy-chain should have a MAC address one number higher, etc.
故障排除指南
If a SystemVu controller is not detected over MS/TP network, verify all the configuration settings like Baud Rate, MAC address and BAS Protocol settings. On i-Vu networks, make sure the source files have been manually imported. NOTE: Use the same polarity throughout the network. Also use a 120-ohm resistor at each end of the network. Network troubleshooting needs to be deliberate and sequential. In the event of rolling communication failures or no communications at all the best approach is to start with the physical layer, then progress to the network layer, and finally the application layer. PHYSICAL LAYER The use of an oscilloscope as described in the Open Controller Network Wiring guide is always the first step. If your waveforms are not clean, packet collisions will occur which will cause losses of communication. Waveforms should look similar to the one shown in Fig. 24, NOT like the distorted (noisy) waveform shown in Fig. 25.

图 25 — 示例ample of Distorted (Noisy) Waveform
A number of factors can cause waveform distortions on the physical layer. Poor wiring hygiene, damaged wire segments, damaged RS-485 transceiver circuits on individual boards, and electrical interference from “noisy” environments are just a few of the issues that can all contribute to physical layer distortions. Isolating portions of the network segment by splitting the communication bus in half repeatedly, while tedious, is the best technique to isolate physical layer defects.
Please note that collisions caused by incorrect network software settings can also lead to distorted waveforms. While not as common as physical layer defects this should be taken into consideration – see section addressing the network layer.
Verify the proper wire is being used and is connected properly at each device and the router. Termination resistors must be at the beginning and end of each bus segment. Ensure network bias resistors are not used since SystemVu is already locally biased. These items are the most common issues found during troubleshooting.
15
NETWORK LAYER
Once any physical layer issues are resolved, the next step is to analyze the network layer. The use of network bus traffic monitoring tools is very valuable when trying to isolate network problems. There are number of tools available, such as Wireshark®1 which allows the diagnosis of issues such as COV over polling, APDU timing, duplicate MAC addresses, etc.
The most common network layer issues are with APDU timeout, BACnet point writes, COV increments, and segmentation setting. SystemVu products are hard set to 6000ms APDU timeout, therefore all devices on the same bus should be set to 6000ms for best results. COV should be disabled unless clearly being used. If COV is being used ensure the refresh increments are set so that COV requests do not occur too frequently. The goal should be for COV requests to occur no more often than every 60 seconds. Ensure BACnet writes/refresh or broadcast rates are reasonable and not occurring too frequently. Usually point writes should not be greater than once per minute. Lastly, ensure packet segmentation is disabled on the network bus.
1. 第三方商标和徽标是其各自所有者的财产。
APPLICATION LAYER
Depending on the router being used, once the physical layer and network layer issues have been resolved, a detailed study of the alarms and alerts present on the router can reveal timing, source file, and software issues. It is best practice for all routers and devices on the network to have updated firmware patches and cumulative patches as applicable.
