Integration (ACnfVal - subsystem-specific extension)

The Analog Configuration Value (ACnfVal) object supports following properties of the subsystem-specific extension Integration.

✳ Indicates a Siemens proprietary property.

Data type ✳
Data type defines the data type for encoding the subsystem-specific data type.
8 bit and 16 bit integer data formats with Registers:
Encoding format	Description	Byte order
U8 S8	unsigned 8-bit signed 8-bit	00 aa 00 aa
U16-B U16-L S16-B S16-L	unsigned 16-bit; big-endian unsigned 16-bit; little-endian signed 16-bit; big-endian signed 16-bit; little-endian	bb aa aa bb bb aa aa bb
In case of U8, S8: the most significant byte is 0.
32 / 64 bit integer data formats with Registers:

S32-B S32-B-S S32-L S32-L-S	signed 32-bit; big-endian signed 32-bit; big-endian; byte swapped signed 32-bit; little-endian signed 32-bit; little-endian; byte swapped		dd cc bb aa cc dd aa bb aa bb cc dd bb aa dd cc
U48-B U48-B-S U48-L U48-L-S	unsigned 48, big-endian unsigned 48, big-endian byte swapped unsigned 48, little-endian unsigned 48, little-endian byte swapped		ff ee dd cc bb aa ee ff cc dd aa bb aa bb cc dd ee ff bb aa dd cc ff ee
S48-B S48-B-S S48-L S48-L-S	signed 48, big-endian signed 48, big-endian byte swapped signed 48, little-endian signed 48, little-endian byte swapped		ff ee dd cc bb aa ee ff cc dd aa bb aa bb cc dd ee ff bb aa dd cc ff ee
U64-B U64-B-S U64-L U64-L-S	unsigned 64, big-endian unsigned 64, big-endian byte swapped unsigned 64, little-endian unsigned 64, little-endian byte swapped		hh gg ff ee dd cc bb aa gg hh ee ff cc dd aa bb aa bb cc dd ee ff gg hh bb aa dd cc ff ee hh gg
S64-B S64-B-S S64-L S64-L-S	signed 64, big-endian signed 64, big-endian byte swapped signed 64, little-endian signed 64, little-endian byte swapped		hh gg ff ee dd cc bb aa gg hh ee ff cc dd aa bb aa bb cc dd ee ff gg hh bb aa dd cc ff ee hh gg
Example: The decimal number 1144201745 (depends on the encoding format) has been sent as an unsigned 32-bit integer data format. Possible encoding: `1144201745 ---> 0x44332211 :` U32-B (high word first, high byte first) `1144201745 ---> 0x33441122 :` U32-B-S (high word first, low byte first) `1144201745 ---> 0x11223344 :` U32-L (low word first, low byte first) `1144201745 ---> 0x22114433 :` U32-L-S (low word first, high byte first)
16 / 32 / 64 bit float data formats with Registers:
Encoding format	Description		Byte order
F16-B F16-L	float 16, big-endian float 16, little-endian		bb aa aa bb
F32-B F32-B-S F32-L F32-L-S	float 32, big-endian float 32, big-endian; byte swapped float 32, little-endian float 32, little-endian; byte swapped		dd cc bb aa cc dd aa bb aa bb cc dd bb aa dd cc
F64-B F64-B-S F64-L F64-L-S	float 64, big-endian float 64, big-endian; byte swapped float 64, little-endian float 64, little-endian; byte swapped		hh gg ff ee dd cc bb aa gg hh ee ff cc dd aa bb aa bb cc dd ee ff gg hh bb aa dd cc ff ee hh gg
Example: IEEE-754 32-bit float data format encoding

Process value 1 and Process value 2Output value 1 and Output value 2 ✳
"Process value 1" (X1), "Process value 2" (X2), "Output value 1" (Y1) and "Output value 2" (Y2) are used to calculate the linear function (f). The linear function is needed to calculate the output value out of the process value. Range: -3.402822E+38...3.402822E+38 Unit: Depends on the selected engineering unit for the output object.
