Parameter Collect

Introduction

ParameterCollectActivity is a process parameter collection node used to collect various parameter data from PLC or other equipment during the production process. Collected data includes:

• Process Parameters
• Material Parameters
• Recipe Parameters
• NG Reason Variables
• Qualification Signal Variables
• SOP Related Variables
• Material Deduction Quantity Variables
• System Shift Variables

Configuration Items

Property Name	Display Name	Type	Required	Default Value	Description
CollectDeliverVariable	Collect Deliver Variable	bool	No	true	Whether to collect recipe deliver parameters
CollectWatchVariable	Collect Watch Variable	bool	No	true	Whether to collect recipe watch parameters
CollectSystemShift	Collect System Shift	bool	No	true	Whether to collect system shift
ParameterVariables	Parameter Variables	ReadParameterVariables	No	Empty	Extra parameter variable collection

Flow Data Items

Input Data Items

Data Item	Type	Description
ApplicationData	ProcessModel	Process Model
SerialNumber	string	Product Code
OutboundQualityVariable	string	Qualification Signal Variable Name
SopPassButton	string	SOP Pass Button Variable
SopRejectButton	string	SOP Reject Button Variable

Usage Example

Basic Configuration

<ParameterCollectActivity Name="Process Parameter Collect">
  <CollectDeliverVariable>true</CollectDeliverVariable>
  <CollectWatchVariable>true</CollectWatchVariable>
  <CollectSystemShift>true</CollectSystemShift>
</ParameterCollectActivity>

Add Custom Collection Parameters

<ParameterCollectActivity Name="Process Parameter Collect">
  <ParameterVariables>
    <Variable VariableName="CustomParam1" />
    <Variable VariableName="CustomParam2" />
  </ParameterVariables>
</ParameterCollectActivity>

Typical Flow Configuration

Inbound Init → Production Processing → Parameter Collect → Qualification Judgment → Parameter Save

<InboundInitializeActivity Name="Inbound Initialization" />

<!-- Production Process -->

<ParameterCollectActivity Name="Process Parameter Collect">
  <CollectDeliverVariable>true</CollectDeliverVariable>
  <CollectWatchVariable>true</CollectWatchVariable>
</ParameterCollectActivity>

<LocalQualificationJudgmentActivity Name="Local Qualification Judgment" />

<ParameterSaveActivity Name="Process Parameter Save" />

Notes

1. Product code must exist, otherwise an exception will be thrown.
2. Collected variable names are automatically deduplicated and empty values filtered.
3. Collection results are stored in ParameterCollectData data item.
4. Subsequent nodes (like Qualification Judgment, Parameter Save) rely on the collection result of this node.
