S5-FB250 Format

With the setting "Ni1000 (TK6180, DIN 43760)" and activated S5-FB250 format,
the I/O module converts the measured resistance values of Ni1000 sensors
(DIN 43760) into temperature values and outputs the conversion results.
The temperature values are displayed at a resolution of 1 digit per 0.05 °C.
The status information is depicted in bit 0 to bit 2 and the digitalized measured
value in bit 3 to bit 15.
