13.5 ModBus: Data types
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.

=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.
