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.
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
• 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
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
= 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.
