Type Description
BYTE Length of field and number of decimal
places. For numbers with decimal
places, the length of the field must be at
least two times greater than the number
of decimal places.
Bit 0 to 3 = Length of Field
1 to F (hex)
Bit 4 to 7 = Number of decimal places
0 to D (hex)
Example: 15 hex means:
Length of field = 5
number of decimal places = 1
BOOL Reserved
BOOL Type of display/mode of representation
(combination of Bit 2 and Bit 3)
(right bit=Bit 2)
00=Normal
01=Flashing
BOOL Representational format, combination of
Bit 4, 5 and 6
(right bit=Bit 4)
000=Decimal
001=Hexadecimal
010=Binary
011=ASCII
100 = Unicode
