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.
Within the Siemens S5 format a value may be converted between decimal
and output value by means of the following formulas.
