8 +== 1.1  Introduction ==
9 +
10 +=== 1.1.1 What is BACnet ===
11 +
12 +
13 +BACnet, short for Building Automation and Control networks.
14 +
15 +The BACnet communication protocol defines a number of services for communication between devices, and services can be divided into five categories: services related to device object management including Who-Is, I-Am, Who-Has, and other services, services related to object access including reading attributes, writing attributes and other services, and services related to alarms and events include acknowledgment alarms, change of state reports, etc. In addition, there are services related to file reading and writing and virtual terminals.

25 +
26 +
27 +By following the steps below in the configuration example, Users can convert the uplink data of the lorawan sensor to BACnet data
28 +
29 +LPS8v2 includes a local ChirpStack Server. This example shows how to configure SN50V3_LB to use with BACnet. This example assumes users already have:
30 +
31 +* SN50V3_LB register on LPS8v2 Built-In ChirpStack server already
32 +* The user is able to see the data on the built-in ChirpStack server device page.
33 +
34 +Below are the steps to configure lps8v2 BACnet.
35 +

50 +
51 +
52 +== 2.3 Configure BACnet ==
53 +
54 +After completing the steps of registering the gateway and nodes as mentioned above, start configuring BACnet
55 +
56 +Video on the configuration of BACnet:
57 +
58 +
59 +=== Step 1. Enable BACnet ===
60 +
61 +First, Uesrs need to click "**BACnet~-~->BACnet Server**" in the page
62 +
63 +1.(% style="color:blue" %)**Enable BACnet**(%%):enable/ disable the BACnet mode
64 +
65 +2.(% style="color:blue" %)**Mode**(%%):Configure the UDP mode
66 +
67 +3.(% style="color:blue" %)**UDP Port**(%%):UDP/IP port number for BACnet/IP communications.
68 +
69 +4.(% style="color:blue" %)**Device ID**(%%):This is the unique BACnet device identifier. The user has to be careful to avoid conflicts, by choosing an identifier, that is not currently used on the network.
70 +
71 +5.(% style="color:blue" %)**Device Name**(%%):Determined by the manufacturer, indicating the device model.
72 +
73 +6.(% style="color:blue" %)**Enable BBMD**(%%):BBMD is a "BACnet/IP Broadcast Management Device" and is used to distribute BACnet broadcast messages throughout a BACnet/IP network consisting of interconnected TCP/IP sub-networks. A BBMD forwards BACnet/IP broadcast messages sent by devices connected to its subnet to peer BBMDs. Upon arrival at a destination BBMD, the message is then re-broadcast on that subnet. BACnet/IP broadcast messages are also sent to registered BACnet/IP Foreign Devices.
74 +
75 +7.(% style="color:blue" %)**BBMD IP Address**(%%):IPv4 address of BBMD or external device registrar.
76 +
77 +8.(% style="color:blue" %)**BBMD IP Port**(%%):UDP/IP port number for external device registration
78 +
79 +9.(% style="color:blue" %)**BBMD Subnet Mask**(%%):UDP/IP Subnet Mask number for external device registration
80 +
81 +10.(% style="color:blue" %)**BBMD TimeToLive**(%%):Number of seconds used in Foreign Device Registration.
82 +
83 +11.(% style="color:blue" %)**Save&Apply**(%%):Click after the configuration is completed
84 +
85 +12.(% style="color:blue" %)**Refresh**(%%):Refresh the configuration
86 +
87 +[[image:image-20250603115501-1.png]]
88 +
89 +
90 +After starting BACnet, use Yabe BACnet tool to check
91 +
92 +Click the "[[image:image-20250603134823-3.png]]" to configure the connection to BACnet. Note that the Port needs to match the previous step, and the local endpoint is the address of the local host

95 +
96 +[[image:image-20250603134854-4.png||height="796" width="1262"]]
97 +
98 +
99 +=== Step 2. Configure BACnet Object ===
100 +
101 +
102 +The user returns to the "**BACnet~-~->BACnet Object**" interface to generate object data
103 +
104 +(% style="color:blue" %)**Object Name**(%%):Show the name of the BACnet object already created.
105 +
106 +(% style="color:blue" %)**Object Type**(%%):Show the type of the BACnet object already created.
107 +
108 +(% style="color:blue" %)**Object Value**(%%):Show the Object value of the BACnet object already created.
109 +
110 +(% style="color:blue" %)**Object Units**(%%):Show the units of the BACnet object already created.
111 +
112 +(% style="color:blue" %)**Object Description**(%%):Set the description of the BACnet object.
113 +
114 +(% style="color:blue" %)**Last Seen**(%%):Show the latest update time of the current value of the BACnet object already created.
115 +
116 +[[image:image-20250603135033-5.png]]
117 +
118 +
119 +When the chirpstack built into the gateway can view the decoded data, click "**Create Objects**" in the "**BACnet~-~->BACnet Object**" page to check the sensor data and add it to the BACnet Object.
120 +
121 +[[image:image-20250603140126-6.png||height="656" width="1247"]]
122 +
123 +
124 +For example, configure the BACnet sensor data as follows
125 +
126 +1.(% style="color:blue" %)**Create Objects**(%%):Create Object
127 +
128 +2.(% style="color:blue" %)**LoRa Device**(%%):Select the sensor device DevEUI that needs to be added
129 +
130 +3.(% style="color:blue" %)**Decode key**(%%):Select the required sensor decoding data
131 +
132 +4.(% style="color:blue" %)**Object Name**(%%):Configure object Name
133 +
134 +5.(% style="color:blue" %)**Object Type**(%%):Select Object Type
135 +
136 +6.(% style="color:blue" %)**Object Units**(%%):Select the Object unit
137 +
138 +7.(% style="color:blue" %)**Object Descripyion**(%%):Set the description of the BACnet object.
139 +
140 +8.(% style="color:blue" %)**Create**
141 +
142 +[[image:image-20250603140746-8.png||height="577" width="1342"]]
143 +
144 +=== step 3. Check Result ===
145 +
146 +After completing all the above configurations, check the BACnet data
