Process Data of the Standard Version 750-464 (RTD,
configurable) Siemens Format
7.4.1
Pt100 (acc. IEC 751)
With the setting "Pt100 (acc. IEC 751)" and activated Siemens format, the I/O
module converts the resistance measured values of Pt100 sensors (acc. IEC 751)
and outputs them as temperature values. 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 "Behavior in the Event of an
Error")
3) When underrange / overrange limit is ON (see section "Behavior in the Event of an Error")
4) Status information: X: Not used, F: Short circuit, wire break, Ü: Overrange
