* Example for clarification:
Bit 3, 6, 8, and 15 are 1. All others are 0. The sum is then 2
= 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

Description
Integer in the range from -32768 to 32767.
The number range actually used for a data point may vary.
Unsigned integers in the range from 0 to 65535.
The number range actually used for a data point may vary.
Is a list. Only one of the values listed in the parameters can be set.
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.
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.
