6.1.5 Sensor Constellation
Reliable system monitoring requires that it be ensured that precisely the same sensors
are connected during operation as were connected at the time the CMU 1000 was
configured.
The
Sensor constellation
is used for this purpose. The sensor constellation is a
monitoring instrument for the connected sensor system, i.e. it performs a continuous
comparison between the connected "Actual" sensor system and the specified
"Nominal" sensor system.
The sensor constellation is optional in the CMU 1000 and not mandatory to have. If
however a sensor constellation has been saved, then the connected sensor system
must match it.
When there is an activated sensor constellation, then an accidental, connected
"incorrect" sensor will be recognized, thus preventing a situation in which the CM
program is working with incorrect information.
A sensor constellation can be saved in files and loaded from files, and can be both
received and transferred by the CMU 1000.
The constellation files all have the extension
*.hescf
.
The sensor constellation contains the following data:
-
Quantity of connected sensors
-
Quantity of subchannels for each connected sensor
-
Status of each individual subchannel (active / inactive)
-
Sensor class (Analog / HSI / SMART)
-
Units of the individual measured values
-
Name of each sensor
-
Device designation of each sensor
If a sensor constellation is available in the CM Editor, then you can use the correct
names in connection with the measurements during program generation. It will then be
the case that only those sensors and subchannels that are actually present will be
available and accessible for adjustment.
A status message at the lower edge of the window of the CM Editor indicates whether
or not a sensor constellation is available.
With the function
Apply from file,
you can open a saved sensor constellation
file and use it in the CM Editor.
To accomplish this, enter the corresponding path and file name in the window
that opens and then click on
Open
.
With the function
Apply from device
, you transfer one of the sensor
constellations stored in the CMU 1000 to your PC, after which you can use it in
the CM Editor.
