Data type Description
BOOL
Boolean value is a parameter with exactly two states (0 — false and 1 —
true). Generally, all values greater than zero are classified as true.
BITMAP*
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.

BITMAP32
Is an array of 32Boolean values (bits). The calculation details can be
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

15
= 8+64+256+32768
= 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.
