Quality Attribute: Validity
If one
invalid signal is received in the case of CFC input data, then all CFC output data will also be set to
invalid if they originate from building blocks without explicit quality processing. In other words, the
quality is not processed sequentially from building block to building block but the output data are set glob-
ally.
This does not apply to CFC output data that originate from building blocks with explicit quality processing
(see next section).
Quality Attribute: Test
CFC chart is in normal state.
CFC chart is in Test
1)
A CFC chart can be switched to the test state by switching the entire device to test mode or the input TEST of
the CFC building block CHART_STATE is set.
Quality Attribute: OperatorBlocked
CFC chart is in normal state.
CFC chart is in functionally logged off
state .
1)
This state only occurs if the device is functionally logged off. In this case, the quality attributes of all CFC
outputs are labeled as functionally logged off.
Quality Processing Building Blocks (Condition Processing)
The first 3 building blocks (x_SPS) process the quality automatically according to the stated logic. The other
building blocks are used to isolate the quality from a data object and add them back after separate logical
processing.

If the CFC chart is executed, then the attribute Test =
for all data leaving the CFC chart. This does not depend on
whether the data are formed via CFC building blocks with or
without quality processing.
In CFC charts for incoming data, the OperatorBlocked attribute
is ignored.
