Setelan Konfigurasi SystemVu BACnet

SystemVu ndhukung tarif Baud ing ngisor iki kanggo BACnet MS / TP.

• 9600
•  19200
•  8400
• 57600
• 76800
•  115200

CATETAN: 115,200 baud rate can only be used with certain devices, such as the iVu® XT-RB router. It can NOT be used on the same MS/TP network with devices such as RTU Open controllers as they do not support this baud rate.
Kanggo konfigurasi Baud Rate lan Alamat MAC, navigasi menyang Setelan BAS ing Antarmuka pangguna nggunakake Menu / Setelan / Setelan Jaringan / BACNET. Waca Fig. 3.

CATETAN: You must cycle power after changing any Network Settings. SystemVu can be connected to the following devices

• All i-Vu BACnet MS/TP routers
• All current i-Vu CCN devices
• Third-party BACnet MS/TP routers
• System Touch over MS/TP
• Equipment Touch over Rnet
•  Carrier Rnet Zone Sensors

CATETAN: SystemVu is a BACnet MS/TP master controller. Valid MAC addresses for master nodes are 0 – 127.

CATETAN: If SystemVu cannot be communicated with over BACnet, then ensure that the protocol has been correctly set and the controller has been power cycled if the protocol settings were changed.

INTEGRASI liwat BACNET MS / TP

• In general, all wiring and installation techniques should follow the Open Controller Network Wiring Guide, Catalogue No. 11-808-461-01, instructions. However, please note the following details and exceptions that MUST be observed on networks containing SystemVu controllers.

Kabel Komunikasi lan Kabel

• Kabel lan kabel komunikasi sing digunakake ing jaringan bisa nyebabake kinerja komunikasi jaringan liwat kabel kasebut. Tindakake rincian sing ditampilake ing Tabel 1 minangka praktik paling apik babagan kabel ing jaringan MS/TP BACnet.

Tabel 1 — Spesifikasi Wiring BACnet MS/TP

CATATAN (S)

•  Merek dagang lan logo pihak katelu minangka properti saka pihak sing duwe.

KABEL KABEL KOMUNIKASI

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 Figs 7 and 8 on page 6). Take care that 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.

AWAS
POSSIBLE COMMUNICATIONS 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.

CATETAN: 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 ing tameng dadi gedhe banget, relatif kanggo lemah bumi, banjur keluwihan voltage getihen karo piranti protèktif ing PROT485 utawa ing pengontrol.

Desain Jaringan

Kanthi pengontrol bias lokal, miturut standar RS-485, jumlah maksimal sing disaranake simpul saben segmen / batang gumantung saka baud rate jaringan.

• 38,400 baud = maksimal 15 simpul lan router
• 76,800 baud = maksimal 31 simpul lan router

Please note that the SystemVu controller is a LOCALLY biased device as opposed to the OPEN product line, which are NETWORK biased device.

• Therefore, the BT485 device is NOT used in a SystemVu-only network, and  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.
• CATETAN: Wigati: Resistor 120 Ohm kudu digunakake kanggo mungkasi bus ing ujung loro miturut syarat standar RS-485. Piranti TERM485 dianjurake.
• With careful wiring practices, one network segment can use up to 4,000 feet of network wire. However, the best results are achieved when the 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.
• Panggunaan piranti PROT485 dianjurake banget kanggo kabeh segmen jaringan kanthi pengontrol SystemVu. Mangga deleng Open Controller Network Wiring Guide kanggo rinci instruksi instalasi PROT485.
• Finally, please note that rigorous adherence to the wiring hygiene recommendations here and in the Open Controller Network Wir-ing Guide will produce the best network results.
• Pengontrol SystemVu kudu duwe kabel BAS sing disambungake menyang plus, minus, lan kabel tameng menyang COM minangka ditampilake ing Fig. 7 lan 8.

Topologi Jaringan

• All BACnet MS/TP networks should be wired in a true “daisy-chain” configuration.
• BACnet MS/TP network best practices dictate that the MAC ad-dressing of the nodes on the network should be sequential with the physical location of the units. For example, yen router iku simpul pisanan ing jaringan, kudu alamat MAC paling. Unit sabanjuré ing daisy-chain kudu alamat MAC siji nomer luwih, etc.

Grounding lan Polaritas

• Lemah bumi sing berkualitas penting kanggo njamin operasi unit sing tepat lan fungsi komunikasi BAS sing tepat.
• There is not one standard ground resistance threshold that is recognised 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 its value for grounding and bonding.
• If you suspect you may have grounding issues at a facility, specialised 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 control-lers allow the shield to float a limited amount so that there are no ground loops. If the voltage ing tameng dadi gedhe banget relatif kanggo lemah bumi, banjur keluwihan voltage getihen karo piranti protèktif ing PROT485 utawa ing pengontrol.

Segmentasi Paket

• Tumpukan BACnet sing digunakake karo produk SystemVu saiki ora ndhukung segmentasi paket.
• Segmentasi kudu dipateni ing piranti pihak katelu.
• Please be aware that the segmentation feature is NOT required for the current BTL (BACnet Testing Laboratories) certification.

i-Vu Integration Tips – Source Files lan Variasi Versi

• The current SystemVu products are compatible with i-Vu versions 7.0 and later. Older versions of i-Vu software may not work cor-rectly with current SystemVu products.
• Kabeh patch i-Vu saiki kudu diinstal nalika nyambung menyang produk SystemVu. Iki bisa dipikolehi saka bagean "Download Kontrol" saka HVACPartners utawa saka Kontrol Pembawa webbagean lunak situs.
• Asring perlu kanggo nambah sumber SystemVu kanthi manual files to the i-Vu server and place them into the appropriate folder.
• Elinga yen sumber files dumunung ing HVACPartners (Saiki dumunung ing TAB Dhukungan> POST SALE Dhukungan> SERVICE SOFTWARE).

COV (Ganti Nilai) lan Router Pihak Katelu

• Fitur COV ing BACnet MS/TP digunakake sacara ekstensif dening sawetara vendor pihak katelu.
• Nanging, SystemVu mung ndhukung sawetara titik COV sing winates. Panjaluk router kanggo titik COV sing ora didhukung dening pengontrol SystemVu bisa nyebabake kesalahan jaringan lan kinerja jaringan sing ora apik.
• Mateni fungsi COV ing piranti pihak katelu bisa dadi alat sing migunani nalika ngatasi masalah lalu lintas jaringan.
• Situs proyek utawa pelanggan tartamtu mbutuhake fitur COV digunakake.
• Yen ngono, Tabel 2 nuduhake titik COV sing tepat sing didhukung dening pengontrol SystemVu.

APDU Timing, Polling Rates, etc. with Third-Party Routers

• Ora umum yen sampeyan kudu nyetel sawetara setelan router sing beda-beda gumantung saka proyek menyang proyek.
• Sayange, ora ana nilai "diset ing watu" sing bisa digunakake ing saben proyek.
• Wigati dimangerteni manawa sawetara nilai kasebut kalebu tarif wektu entek APDU, tarif polling, lan tarif wektu entek NPDU.
• 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 Othe APN022 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 to have the  APDU segment size or RPM “chunking” or “bin packing” algorithms mare manually adjusted to properly work with features such as Read Property Multiples.

Frame Rate lan Router Pihak Katelu

• 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 an older SystemVu
• units is experiencing issues; upgrading to current production software is recommended.
• Unit produksi A2L saiki duwe tingkat pigura sing bisa diatur lan nilai master maksimal.

INTEGRASI SYSTEMVU karo SYSTEM TOUCH liwat MS / TP PORT

Apa Sistem Tutul

• The System Touch is a touchscreen device with a color LCD dis-play that provides as a user interface to controllers on a single BACnet network.

Pengalamatan pengontrol

• Each SystemVu controller on the MS/TP network must have a unique BACnet MS/TP MAC address, which is set by the User In-terface Menu. Valid addresses are 1-99.
• BACnet MS/TP network best practices dictate that the MAC ad-dressing of the nodes on the network should be sequential with th e 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.

Pedoman ngatasi masalah

• Yen controller SystemVu ora dideteksi liwat MS / jaringan TP, verifikasi kabeh setelan konfigurasi kaya Baud Rate, alamat MAC lan setelan Protokol BAS. Ing jaringan i-Vu, priksa manawa sumber 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.

LAPISAN FISIK

• The use of an oscilloscope as described in the Open Controller Network Wiring guide is always the first step. If your wave-forms 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.

• Sawetara faktor bisa nyebabake distorsi gelombang ing lapisan fisik. Kebersihan kabel sing kurang apik, segmen kabel sing rusak, sirkuit transceiver RS-485 sing rusak ing papan individu, lan gangguan listrik saka lingkungan "rame" mung sawetara masalah sing bisa nyebabake distorsi lapisan fisik. Ngisolasi bagean saka segmen jaringan kanthi misahake bis komunikasi dadi setengah bola-bali, nalika mboseni, minangka teknik paling apik kanggo ngisolasi cacat lapisan fisik.
• 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.
• Priksa manawa kabel sing bener digunakake lan disambungake kanthi bener ing saben piranti lan router. Resistor terminasi kudu ana ing wiwitan lan pungkasan saben segmen bis. Priksa manawa resistor bias jaringan ora digunakake amarga SystemVu wis bias lokal. Item kasebut minangka masalah sing paling umum ditemokake nalika ngatasi masalah.

LAYER JARINGAN

• Once any physical layer issues are resolved, the next step is to analyse the network layer. The use of network bus traffic monitoring tools is very valuable when trying to isolate network problems. There are a 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 settings. SystemVu products are hard-set to a 6000ms APDU timeout; 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.

APLIKASI LAYER

• Gumantung saka router sing digunakake, yen masalah lapisan fisik lan lapisan jaringan wis dirampungake, studi rinci babagan weker lan tandha sing ana ing router bisa mbukak wektu, sumber. file, lan masalah piranti lunak. Praktek paling apik kanggo kabeh router lan piranti ing jaringan duwe patch perangkat kukuh sing dianyari lan patch kumulatif sing ditrapake.

Pitakonan

Can untrained personnel perform maintenance on the SystemVu controller?

Untrained personnel can perform basic maintenance tasks such as cleaning coils and filters, but all other operations should be handled by qualified service personnel.
