S5-FB250 Format

With the setting "Pt200 (IEC 751)" and activated S5-FB250 format, the I/O
module converts the measured resistance values of Pt200 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.

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" > "Behavior in
the Event of an Error")
3) When underrange / overrange limit is ON (see section "Diagnostics" > "Behavior in the Event of
an Error")
4) Status information:
