In Siemens S5 format, input data is saved into a word. The word consists
of the binary value and the information bits.
Please regard only the Siemens S7 format (two's complement) is
supported by the Siemens SIMATIC manager for decimal representation.
When the Siemens S5 format is used the decimal values are incorrectly
represented.
Numeric notation:
Byte Bit 7 ... Bit 0
0 Bit 0: overflow bit
0: value within measuring range
1: measuring range exceeded
Bit 1: error bit (set by internal errors)
Bit 2: activity bit (always 0)
Bit 7 ... 3: binary measured value
1 Bit 6 ... 0: binary measured value
Bit 7: sign
0 positive
1 negative
