S5-FB250 Format

With the setting "Pt100 (IEC 751)" and activated S5-FB250 format, the I/O
module converts the resistance measured values of Pt100 sensors (IEC 751) and
outputs them as temperature values. 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.

1) Temperature values below 0 °C are represented in two's complement binary.
2) When short circuit and wire break monitoring is on (see Section "Diagnostics" > "Error
Response")
3) When lower/upper limit violation detection is on (see Section "Diagnostics" > "Error Response")
4) Status information:
X: Not used,
F: Short circuit, wire break,
Ü: Range upper limit violation, range lower limit violation, under-range, over-range
