Parameters/address space
4.3 Explanation of parameters
Diagnostics: Overflow
Enabling of the diagnostics when the measured value exceeds the overrange.
Diagnostics: Underflow
Enabling of the diagnostics if the measured value falls below the underrange.
Diagnostics: Wire break
Enabling of the diagnostics if the module has no current flow or the current is insufficient for
measurement at the correspondingly assigned input.
Type/range of measurement
See the section Measurement types and measuring ranges (Page 17).
Temperature coefficient
The temperature coefficient depends on the chemical composition of the material. In Europe,
only one value is used per sensor type (default value).
The temperature coefficient (α value) indicates by how much the resistance of a specific
material changes relatively if the temperature increases by 1 °C.
The other values facilitate a sensor-specific setting of the temperature coefficient and
enhance accuracy.
Temperature unit
Selection between Degrees Celsius, Fahrenheit and Kelvin as the temperature unit for the
selected measuring range.
