Inbound Initialize

Introduction

InboundInitializeActivity is a MES-specific inbound initialization node used to initialize various state variables and verify the validity of the product code when a product enters the station. This node is the starting point of the inbound flow, responsible for setting key information such as inbound results and work types, and initializing the recipe applied to the current process.

Configuration Items

This node is configured and outputs via flow context variables, no direct property configuration is needed.

Input Variables

Product Code Verification

When the product code is empty, the system determines the error type based on the association description:

Condition	Inbound Result	Description
Tray code association desc initialized	TrayCodeNotBoundProductCode	Tray code not bound to product code
Material code association desc initialized	MaterialCodeNotBoundProductCode	Material code not bound to product code
Other cases	NoProductEntry	No product entry

Recipe Initialization

Decides whether to initialize the recipe based on system configuration:

Configuration Condition	Behavior
FormulaDistributionMode = 2	Distribute recipe when process identifies product, requires initialization
PluginState = 0	Order management plugin disabled, requires initialization
Other cases	Do not initialize recipe in this node

Inbound Result Configuration

Result Name	Constant	Description
OK	EntryResultConfig.OK	Inbound Success
NoProductEntry	EntryResultConfig.NoProductEntry	No Product Entry
TrayCodeNotBoundProductCode	EntryResultConfig.TrayCodeNotBoundProductCode	Tray Code Not Bound to Product Code
MaterialCodeNotBoundProductCode	EntryResultConfig.MaterialCodeNotBoundProductCode	Material Code Not Bound to Product Code
NG	EntryResultConfig.NG	Inbound Failed (Recipe not found, etc.)

Notes

1. Flow Start: This node is usually the first business node in the inbound flow.
2. Product Code Required: If product code is empty, an error result is set, subsequent nodes should check the inbound result.
3. Recipe Initialization: Decides whether to initialize recipe here based on system configuration.
4. State Reset: Resets relevant state variables on every inbound.
