7.2.8 Error Event
An error handling can be implemented with the function
Error event
.
The Boolean output is switched to "1" in the event that an error
condition is present. The output is switched back to "0" if the error
goes away.
The type of error event can be set with the
Event
parameter.
The following events are possible:
Below signal range
A sensor has cable breakage, for example
Above signal range
One sensor lies above the signal range with its signal
Incorrect sensor constellation
At one sensor connection port there is either no sensor connected,
or an incorrect one.
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.
Inputs -
Outputs: y: (Boolean)
Parameters: p
1
:
Event
(input list)
7.2.9 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.
Inputs -
Outputs: y: (Boolean)
Parameters: p
1
: Value
(Boolean)
7.2.10 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.
Inputs -
Outputs: y: (Boolean)
Parameters: p
1
:
Sensor port
(Channel A .. Channel H)
p
2
:
Bit location
(0 .. n -depending on sensor-)
