KNX Datapoint types
Các loại cấu trúc dữ liệu Datapoint types DTP thường gặp
The most often used Datapoint Types are:
1.yyy = boolean, like switching, move up/down, step
2.yyy = 2 x boolean, e.g. switching + priority control
3.yyy = boolean + 3-bit unsigned value, e.g. dimming up/down
4.yyy = character (8-bit)
5.yyy = 8-bit unsigned value, like dim value (0..100%), blinds position (0..100%)
6.yyy = 8-bit 2's complement, e.g. %
7.yyy = 2 x 8-bit unsigned value, i.e. pulse counter
8.yyy = 2 x 8-bit 2's complement, e.g. %
9.yyy = 16-bit float, e.g. temperature
10.yyy = time
11.yyy = date
12.yyy = 4 x 8-bit unsigned value, i.e. pulse counter
13.yyy = 4 x 8-bit 2's complement, i.e. pulse counter
14.yyy = 32-bit float, e.g. temperature
15.yyy = access control
16.yyy = string -> 14 characters (14 x 8-bit)
17.yyy = scene number
18.yyy = scene control
19.yyy = time + data
20.yyy = 8-bit enumeration, e.g. HVAC mode ('auto', 'comfort', 'standby', 'economy', 'protection')
