Version 1.1.0
4.3.12.2 S5-FB250 Format
With the setting “Pt1000 (IEC 751)” and activated S5-FB250 format, the I/O
module converts the measured resistance values of Pt1000 sensors (IEC 751) 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.
