# Hub IO Path Updates

## Overview
Updated the PLC Data Generator to support two different Hub IO path configurations:
- **SorterHub**: For hubs with "S0" in their tagname (e.g., S01_FIOH1, S02_FIOH2)
- **Hub**: For regular hubs without "S0" in their tagname

## Changes Made

### 1. Excel File Structure (IO-To-Path.xlsx)
- The original "Hub" sheet has been renamed to "SorterHub"
- A new "Hub" sheet has been created for regular hub configurations
- Both sheets maintain the same column structure: IO, IPath, OPath

### 2. Code Updates

#### io_paths.py
- Updated `load_io_path_mappings()` to load both Hub and SorterHub sheets
- Modified `get_io_path()` to automatically select the correct sheet based on tagname:
  ```python
  if device_type == 'Hub':
      # Check if the hub has S0 in its name to determine which sheet to use
      if 'S0' in str(tagname).upper():
          df = sorter_hub_df
      else:
          df = hub_df
  ```

#### main.py
- Updated to handle the additional sorter_hub_df parameter from load_io_path_mappings()
- Passes sorter_hub_df to process_data()

#### process.py
- Updated function signature to accept sorter_hub_df parameter
- Passes sorter_hub_df to get_io_path() calls

## Usage
No changes required from the user perspective. The system automatically:
1. Detects if a hub tagname contains "S0"
2. Uses the appropriate IO path mapping sheet
3. Generates correct IO paths based on the hub type

## Testing
Tested successfully with MCM01 data, showing proper loading of both Hub sheets and 100% successful IO path mappings.
