Composite Qualification Judgment

Introduction

CompositeQualificationJudgmentActivity is a composite qualification judgment node that executes both PLC qualification judgment and local qualification judgment. The final result is qualified only when both judgments are qualified.

This node is suitable for scenarios requiring dual verification: Equipment Detection + System Verification.

Configuration Items

Property Name	Display Name	Type	Required	Default Value	Description
ExclusionValue	Exclusion Value	double?	No	null	Skip verification for this parameter when value equals this
IgnoreNull	Ignore Null	bool	No	false	If collected value is null, ignore it and do not judge as NG

Composite Judgment Rules

PLC Result	Local Result	Final Result	Unqualified Reason
Qualified(1)	Qualified(1)	Qualified(1)	Empty
Qualified(1)	Unqualified(2)	Unqualified(2)	Local Reason
Unqualified(2)	Qualified(1)	Unqualified(2)	PLC Reason
Unqualified(2)	Unqualified(2)	Unqualified(2)	PLC Reason|Local Reason

Usage Example

Basic Configuration

<CompositeQualificationJudgmentActivity Name="Composite Qualification Judgment">
  <ExclusionValue>-999</ExclusionValue>
  <IgnoreNull>false</IgnoreNull>
</CompositeQualificationJudgmentActivity>

Typical Flow Configuration

<ParameterCollectActivity Name="Parameter Collect" />

<CompositeQualificationJudgmentActivity Name="Composite Qualification Judgment">
  <IgnoreNull>true</IgnoreNull>
</CompositeQualificationJudgmentActivity>

<ConditionActivity Name="Quality Judgment">
  <Condition>Flow.DataItems["QualityResultValue"] == 1</Condition>
  <TrueBranch>Qualified Handling</TrueBranch>
  <FalseBranch>Unqualified Handling</FalseBranch>
</ConditionActivity>

Comparison of Three Judgment Methods

Feature	PLC Judgment	Local Judgment	Composite Judgment
Basis	PLC Signal	Recipe Parameters	Both
Configuration	Simple	Medium	Medium
Reliability	Dependent on Equipment	Dependent on Recipe	Double Assurance
Scenario	Equipment Detection	System Verification	Critical Process

Notes

1. Composite judgment executes both PLC and local judgments simultaneously.
2. Final result is qualified only when both are qualified.
3. Unqualified reasons are merged and separated by |.
4. Parameter Collect node must be executed before this node.
