Input data in Siemens S5 format is stored in a word. The word contains the
binary value and information bits:
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 at internal error)
Bit 2: activity bit (always 0)
Bit 7 ... 3: binary measured value (see table below)
1
Bit 6 ... 0: binary measured value (see table below)
Bit 7: sign
0 positive
1 negative
The following table shows the allocation of binary values to the respective
measured values.
