Signed integer value, 1 byte (-128 to 127)

Signed integer value, 2 bytes (-32,768 to 32,767)

Signed integer value, 4 bytes (-2,147,483,648 to 2,147,483,647)

Unsigned integer value, 1 byte (0 to 255)

Unsigned integer value, 2 bytes (0 to 65,535)

Unsigned integer value, 4 bytes (0 to 4,294,967,295)

Floating point number, single precision, 4 bytes (≈-3.^4*1038 to +3.^4*1038)

Floating point number, double precision, 8 bytes (≈-1.^7*10308to +1.^7*10308)

Boolean value (0, 1)

Auxiliary data type for accessing individual bits in a structure definition. If required, this can be used as an alternative to VT_BOOL if the communication component (driver) supports this. An extended description of the offset is expected in the order number parameter for VT_BIT: <byte number>,<bit number>.

example: The specification of 0.1 in the ordinal number parameter sets the byte offset of the structure element of data type VT_BIT to byte 0, bit 1.

Note: The specification of 0.0, 1.0, 2.0 etc. is not permitted. Instead, enter 0, 1, 2 etc., for example.
