3. SPC Preparation: Points

Although there are areas in SPC where values can be entered manually, CIMPLICITY points are at the core of data collection and evaluation.

Points can be created at any time and used in the SPC configuration.

However, the following list of fields where runtime points might be used may help you create a logical naming convention as processes are evaluated and monitored.

  • Points: For Variables
  • Points: For Attributes
  • Points: For Defects
Note: These fields are based on runtime points being selected as the data source. The points can also be logged and logged values used as the data source. If you use logged values, make sure to check Logged Data on the Point Properties dialog box>General tab for the points that will be logged.
