Behavior on error
Limits according to NAMUR recommendation NE 43:
Zero point and end value
Specifying the zero point and end value (scaling) assigns a value range to the physical output
signal. The factory setting corresponds to a value range of 0 to 100 (e.g. output level from 0 %
to 100 % for a controller output).
If, for example, a temperature with a value range from 150 °C to 500 °C is issued via an analog
output with signal type 0 ... 20 mA, the zero point is set to 150 (corresponds to 0 mA) and the
end value is set to 500 (corresponds to 20 mA).
Status after change of configuration
Modified parameters are incorporated immediately.
Behavior after power on
During the initialization phase of the controller module, the output signal adopts a value of 0 %
(in relation to the value range of the signal type).
Error processing
The behavior in the event of deviation above or below the measuring range (out of range) can
be configured. The settings also apply for probe/conductor breaks or probe/conductor short-
circuits. This produces a safe state for operation in the event of an error.
Error detection depends on the type of measuring probe (see technical data, measuring circuit
monitoring).
Signal at O-o-R 0 to 100 % Value of the output signal in the event of
deviation above or below the measuring
range (in relation to the value range of
the signal type)
Zero point -1999 to 0 to +9999 Start of scaling
End value -1999 to 100 to +9999 End of scaling
