5.4.2 Pt1000 sensor inputs
The process images of the Pt1000 sensor inputs (for details, see chapter
Assignment of the analogue inputs
)
provide a signed 16-bit integer value that is a factor of 10 higher than the measured temperature value in °C.
For further use, this value is usually divided by 10 and assigned to a REAL variable.
The following table shows the connections:
Measured value

16#8080 = 32896
The 16-bit value range is: -32768 .. 32767. Therefore, in the
Signal List
for the Pt1000 sensor inputs,
e.g. for the sensor Pt1000_1, the value II26 and not IW26 is entered in order to record the negative
number range.
