S5-FB250 Format

With the setting "Pt100 (IEC 751)" and activated S5-FB250 format, the I/O
module converts the measured resistance values of Pt100 sensors (IEC 751) into
temperature values and outputs the conversion results.
The temperature values are displayed at a resolution of 1 digit per 0.5 °C.
The status information is depicted in bit 0 to bit 2 and the digitalized measured
value in bit 3 to bit 15.
