# Load Feeder to Position

## Overview

This feature enables the load of Consumable Feeds with Consumables to Station Position.

### Relevant Artifacts

The table below describes the properties for this entity type:

| Name                                                                             | Type       | Is Mandatory | Data Type | Description                                                    |

| IoTMetadataDefinition                                                            | SmartTable |     Yes      |           | Metadata configuration for equipment integration               |
| [IoTFujiNeximLoadComponents](../../artifacts/dees.md#iotfujineximloadcomponents) | DEE        |     Yes      |           | Its purpose is to Attach feeders from a specified MES resource |
| /IoT/AllowReelCreationOnComponentLoad                                          | Config     |     Yes      |           | Determines whether reels can be created in MES if they do not already exist |

## How It Works

When a `LOADCOMP` event is received from a Fuji NXT III machine, the following steps are executed:

### Area Feature Checks

- Resolves the MES Resource Name using `FUJI_LineNameMachineNameModuleNo_`.

### Resource Feature Checks

- It checks whether the `UseFujiToLoadComp` feature is enabled for the MES Resource in `IoTMetadataDefinition`.

### MES Operations

If the feature is enabled, the Automation Controller calls the DEE [IoTFujiNeximLoadComponents](../../artifacts/dees.md#iotfujineximloadcomponents), passing:

- The MES Resource Name
- A list of components to be loaded, including their positions

The DEE:

- Sets the **Consumable Feed relations**
    - If Material and Feeder already exist, they are attached to the corresponding Resource.
    - If Material does not exist:
        - When the `AllowReelCreationOnComponentLoad` configuration is set to `true`, the Material is created during the transaction and then attached.
        - When the `AllowReelCreationOnComponentLoad` configuration is set to `false`, an exception is thrown.
- Updates the **quantity of the consumables**

Sends a `LOADCOMP_ACK` message back to the equipment, which includes:

- A list of components
- A result (`0 (Ok)` or `1 (NOk)`) for each component
- Remaining Floor Life time (if already started in MES)

**Error Handling**  
   If any component fails during the DEE operation, the entire set operation is considered failed.

**Bypass Condition**  
   If `UseFujiToLoadComp` is set to `False` or not defined, the DEE call is bypassed entirely.

### Assumptions

SmartTable IoTMetadataDefinition is configured with the following entry for each station:

| Resource                    | ResourceType | Area | Name              | Value |
| --------------------------- | ------------ | ---- | ----------------- | ----- |
| MES Fuji Station X Resource |              |      | UseFujiToLoadComp | True  |
