Parameters For Analog Output Modules U, I - Siemens SIMATIC ET 200S Manual

Analog Electronic Modules
Temperature coefficient
The correction factor for the temperature coefficients (α value) indicates the
relative change of the resistance of a specified material if the temperature
increases by 1_C.
The temperature coefficient depends on the chemical composition of the material.
In Europe only one value is used per sensor type (default value).
The additional values enabled sensor-specific adjustment of the temperature
coefficients and therefore even greater precision.

If the power to the IM is disconnected and the analog output modules are still powered, the configured
substitute values are output. Substitute values must be within the nominal range. Values from --27648 to
+27648 are configured (when configured with the GSD file).
