13.1
Error messages in float values and on the display
The display is shown as a float value itself. The following statuses are defined.
Error
First error value
Software – underrange
Software – overrange
No valid input value
Division by zero
Incorrect mathematical value
Display capacity exceeded
Invalid value
In the event of an error, the device function reports this error itself in its output value. All device
functions monitor an input value for these error values. In the event of an error, the output value
is applied in turn to one of these error values, or another value is specified in the configuration
(error value/substitute value).
13.2
Display of error messages for binary values
Binary input values are only displayed with 0 and 1. If no valid input value is available, or the
device function cannot deliver a valid output value, the value is set to 0.
Exception
In the configuration level you can set which value the output should accept in the event of an
error (error value/substitute value) and this value is then faded in.
Start/end display:
The graphic display elements of the display range are established for this (lower and upper limit
in a bar graph display). The numeric representation is dependent on the display start/end and
is produced from the entire measuring range. In the recording, measured values smaller than
the display start are saved as UNDERRANGE and measured values larger than the display
end are saved as OVERRANGE.
Bar graph display:
The numeric representation is dependent on the display start/end and is produced from the en-
tire measuring range. In the recording, measured values smaller than the display start are
saved as UNDERRANGE and measured values larger than the display end are saved as
OVERRANGE.
Over- and underrange:
Detection is performed at hardware limits and on the scaling in mV. The maximum number of
display ranges are therefore always available. For all the values calculated in the device such
as mathematics output, flow rate, and external inputs, the following applies: The display range
has the same significance here as for hardware inputs.
