⼗三、应⽤类型
编码的 BACnet 应⽤标记的标记编号域表⽰应⽤数据类型， 参数分配如下：
标记编号：
0 = Null
1 = Boolean
2 = Unsigned Integer
3 = Signed Integer (2’ complement notation)
4 = Real (ANSI/IEEE-754 floating point)
5 = Double (ANSI/IEEE-754 double precision floating point)
6 = Octet String
7 = Character String
8 = Bit String
9 = Enumerated
10 = Data
11 = Time
12 = BACnetObjectIdentifier
