Data type
Description
INT16
Integer in the range from -32768 to 32767.
The number range actually used for a data point may vary.
UINT16
Unsigned integers in the range from 0 to 65535.
The number range actually used for a data point may vary.
ENUM
Is a list. Only one of the values listed in the parameters can be set.
BOOL
A 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 the
value 1 multiplied by 2 to the power of its index.

BITMAP32
Is an array of 32 Boolean values (bits). Please check Bitmap for the calcula-
tion details.
* Example for clarification:
Bit 3, 6, 8, and 15 are 1. All others are 0. The sum is then 2

15
= 8+64+256+32768
= 33096. It is also possible to do the calculation the other way round. 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 num-
ber is repeated until bit 0 is obtained or the residual number is zero. Example for clarifica-
tion: The read number is 1416. Bit 15 will be 0, since 1416 < 32768. Bits 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. Bits 6 to 4 will be 0. Bit 3
will be 1, since 8 = 8. The remainder will be 0. The remaining bits 2 to 0 will thus all be 0.
