Event Objects

The SPC module can capture sample data in a number of different ways...

• Tags can be configured to automatically capture sample data by using the Automatic Tag Sample Collector. 
• Sample definitions can be created in a Sample Definitions screen that uses the quality components that allows the manual entry of sample values.
• Scripting can be employed to create samples.
  
  

However samples are introduced, the SPC engine will perform the necessary calculations based on the Control Limits, Out of Control Signals and Misc. Calculations that have been defined and enabled for that sample.

The SPC Engine will generate an event when a sample point is received and a calculation is performed. Custom scripting can be added to the default calculation event script.

The SPC events can be viewed in the quality tab of the production model in designer at the enterprise level. Whenever an event is fired, a Calculation Kind Types object is passed to the event. You can use this object to get information about the event and the object. SPC object events also allows user to add custom scripts and events in the same way as the MES object events. For more information custom scripting read the Object events section.

Sample Events

The SPC Sample Events (Production Location Events) can be viewed in the MES Equipment Manager's SPC section at the location level. The following events can be used to change the default handling of samples and signals.
