SPC Sample Definition Manager

Use the SPC Sample Definition Manager component to modify and configure Sample Definition Classes and Sample Definitions that are used for quality testing in the SPC module. Sample Definitions are organized in Sample Definition Classes.  This component can be used to add, edit, delete, copy and paste a Sample Definition or Sample Definition Class.

The SPC Sample Definition Manager component allows for the management of Sample Definitions and the sample Definition Classes that hold them. By selecting a Sample Definition, the Attributes, Locations, Signals (Rules) and Control Limits associated with it can be accessed and edited.

Hierarchy Tree

The Hierarchy Tree area depicts the parent-child relationships of the Sample Definition Classes and Sample Definitions that exist in this gateway.

Collapsing and then expanding the tree at the top node will refresh the tree's contents if they have changed.

Sample Definition Classes are depicted with a folder icon (   ). Sample Definition Classes can be created as children to other Sample Definition Classes, but not as children to Sample Definitions.

Sample Definitions are depicted with a pencil and paper icon ( ). Sample Definitions can be created as children of Sample Definition Classes, but not as children to other Sample Definitions.

General

The commands in this area act upon whichever Sample Definition Class or Sample Definition is highlighted (clicked on) in the Hierarchy Tree. When not permitted for the selected item, the command will be grayed out.

Sample Definition Settings

For each Sample Definition, there are various properties that control how sample collection will occur. These are located in the Sample Definition Settings section of the component:

• Attribute List — Defines the data measurements to collect for each sample. Attributes can be exported and then imported into other Sample Definitions.
  
  
• Locations — Selects the available Location (created in the Production Model in an Area or Line) to associate with the Sample Definition.
  Note: The Hierarchy tree will only display Lines and Areas that have a Location:
  

• Rules (to generate Signals) — Defines which out-of-control rules to apply to the Sample Definition (e.g. Individual Nelson Rule 3) for signal generation.
  
  
• Control Limits — Defines which control limits to enable for the Sample Definition.

Sample Definition Classes and Sample Definitions

See Sample Definitions page for using this component to create and edit Sample Definition Classes and Sample Definitions, add Attributes, Locations, Rules (to generate Signals) and Control Limits.

Sample Definition Class

A Sample Definition Class acts a folder to hold Sample Definitions. Classes can be nested, allowing for hierarchical organization.

Sample Definition

A Sample Definition object holds all of the information defining a type of sample. It specifies the Attributes to collect, the Locations where sample data is collected from, as well as the Rules (to generate Signals) and Control Limits that apply.

When samples are created, they are based on a Sample Definition. When sample measurement values are recorded, the Sample Definition is used to validate the measurement values.

Component Properties

Properties are provided that can be set to affect the operation and look of the component. They can be set through the Property Editor in the Designer or through scripting.

Example

Extension Functions

filterSampleDefinition

# This example only displays definitions that have a description set
	filteredList = []
	for definitionLink in definitionList:
		if definitionLink.getMESObjectType().getName() == 'SampleDefinition':
		definition = definitionLink.getMESObject()
		if definition.getDescription():
			filteredList.append(definitionLink)
		else:
			filteredList.append(definitionLink)

	return filteredList

loadIcon

# This example will return a path to a different image to replace the default delete image:
if iconName == 'edit':
	return 'Builtin/icons/24/edit2.png'

Custom Methods

Custom methods allow you to add your own component functions to a component that can be called through scripting. This is a useful and clean method of re-using script that is specific to the component (say you want to update a visual aspect of the component in the same way whether a user clicks on the component or a window property value changes). See Component Custom Methods in the Ignition Help Manual for more information.

Custom Properties

The custom properties can be used to add user defined properties.
