The process capability chart is a frequency histogram and distribution of the sample data currently displayed (on the Mean chart). Plant SCADA automatically takes the data being trended, builds a distribution, adds the LSL and USL. It also calculates the Cp, Cpk, kurtosis, and skewness indices.
The process capability is defined in relation to the upper and lower specification limits (USL and LSL) for a given SPC Tag. These values are defined in SPC Tags and accurately represent the users requirements.
To configure a capability chart:
-
Define the SPC Tags and specify the LSL and USL.
-
Create the page using a Capability (Cpk) template.
