The building blocks also process the supported quality attributes according to their logic.
The following tables describe the logic using input values in connection with the quality
attribute Validity. The input values are 0 or 1, the quality attribute Validity can have the
value good (=g) or invalid (=i).
x = placeholder for the input value and quality attribute Validity
OR_SPS
A (Value, Attribute)
0, i
0, g
1, g
1, i
1, i
The output thus has the logical value 1 with Validity =
the logical value 1 with Validity =
OR operation and the INVALID bit is OR-gated for the quality.
AND_SPS
A (Value, Attribute)
0, g
0, i
1, i
1, g
The output thus has the logical value 0 with Validity =
the logical value 0 with Validity =
AND operation and the INVALID bit is OR-gated for the quality.
NEG_SPS

0, i
0, g

The building blocks isolate the data value and quality of a data object.
The requirement is that the quality is available from the input end. This is the case if the
building block is interconnected with CFC input data, or is connected downstream with a
quality processing building block (x_SPS). In other cases, the CFC editor does not allow a
connection.
The building block performs binary separation of the quality into
test , off and OperatorBlocked .
These 5 attributes can then be processed individually in a binary operation. The building
block must be connected downstream to a SPLIT_(DO) building block.
The building block enters a binary value for
structure. Thus, with this building block the quality attributes
can be set explicitly, for example, as the result of a monitoring logic.
All other quality attributes are set to the default state, for instance, Test =
example, the entire CFC chart is in the test state (see Quality Attribute: Test Under General
Processing), this default status can again be overwritten on the CFC output side.
The building block is normally connected downstream to a BUILD_(DO) building block.
