Parameter assignment of discrepancy analysis for 1oo2 evaluation
Operating principle of discrepancy analysis
A discrepancy analysis is performed with a configured 1oo2 evaluation.
Smoothed
process
values are used for the discrepancy analysis.
An assignable tolerance window is formed around the process value that represents the
instantaneous standard value (value that is signaled to the F-CPU).
The tolerance window is formed relative to the process value or as an absolute value relative
to the measuring range end value. Relative and absolute tolerance windows are combined.
If the process value does not represent the standard value at an instant and is within the
tolerance window,
no
discrepancy exists.
Figure 4-1 Example of a relative tolerance window
without discrepancy (parameter assignment:
standard value = MAX)
