Data State

Data State
The following information can be shown:

• Undefined:

Undefined:

Undefined: The system is not running; no information is available.

• Unknown:

Unknown:

Unknown: The system is filling the internal FIFOs. There is not enough information available
to estimate the pipeline conditions (possible after a restart of the system). The information
will be available soon.

• OK (green):

OK (green):

OK (green): All measured data is available.

• Warning (yellow):

Warning (yellow):

Warning (yellow): Minimum one measured data is not available. This measurement is not
