A.2.8 Error Event
Error handling can be implemented with the function Error event.
The Boolean output is switched to "1" when an error condition is
present. The output is switched back to "0" if the error disappears.
The type of error event can be set with the Event parameter.
The following events are possible:
Below signal range
A sensor has a cable break, for example
Above signal range
The signal of one sensor is above the signal range
Incorrect sensor constellation
There is either no sensor, or an incorrect sensor connected to one
sensor connection port.
Numerical error
An error occured during a calculation, e.g. division by 0 or square
root of a negative number, logarithm from 0, etc.
Cycle time exceeded
The set cycle time was exceeded.

A.2.9 Boolean Constants
The Boolean Constant function supplies a Boolean value which is
defined in the Editor and which does not change during the running
time. That means that the parameter entered in the Editor is output
during the running time at the output.

Value (Boolean)
A.2.10 State-bit
The function Show Stat-bit provides the status of the bit defined by
the "Sensor port" and "Bit location" parameters in the status code of
the selected SMART sensor (status code is sensor-specific) at the
Boolean output.
