13.4 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 16Boolean 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.
