Data type Description
Boolean value is a parameter with exactly two states (0 — false and 1 —
BOOL
true). Generally, all values greater than zero are classified as true.
Is an array of 16 Boolean values (bits). Values are indexed from 0 to 15.
The number read from or written to the register is the sum of all bits with
value 1 multiplied by 2 to the power of its index.
0
▪ Bit 0: 2 = 1
1
▪ Bit 1: 2 = 2
2
▪ Bit 2: 2 = 4
3
▪ Bit 3: 2 = 8
4
▪ Bit 4: 2 = 16
5
▪ Bit 5: 2 = 32
6
BITMAP* ▪ Bit 6: 2 = 64
7
▪ Bit 7: 2 = 128
8
▪ Bit 8: 2 = 256
9
▪ Bit 9: 2 = 512
10
▪ Bit 10: 2
11
▪ Bit 11: 2
12
▪ Bit 12: 2
13
▪ Bit 13: 2
14
▪ Bit 14: 2
15
▪ Bit 15: 2
Is an array of 32 Boolean values (bits). The calculation details can be
BITMAP32
found in the description for Bitmap.
* Example for clarification:
Bit 3, 6, 8, 15 are 1 all others are 0. The sum is then 2
= 33096. The other way round is also possible. Based on the bit with the highest index,
check whether the read number is greater than/equal to the power of two. If this is the
case, bit 1 is set and the power of two is deducted from the number. Then the check
with the bit with the next lower index and the recently calculated residual number is re-
peated until bit 0 is obtained for bit or the residual number is zero. Example for clarific-
ation: The read number is 1416. Bit 15 will be 0, since 1416 < 32768. Bit 14 to 11 will
also be 0. Bit 10 will be 1, since 1416 > 1024. The remainder will be 1416-1024=392.
Bit 9 will be 0, since 392 < 512. Bit 8 will be 1 since 392 > 256. The remainder will be
392-256=136. Bit 7 will be 1 since 136 > 128. The remainder will be 136-128=8. Bit 6
to 4 will be 0. Bit 3 will be 1 since 8=8. The remainder will be 0. Residual bits will thus be
2 to 0.
