# Documentation: CAN Configuration Module

## 1. Purpose

This module provides XML-serializable configuration management for CAN (Controller Area Network) data acquisition system modules. It exists to persist and retrieve hardware module configurations—including serial numbers, test metadata, recording parameters, and channel definitions—to/from XML files stored in a `DASConfigs` subdirectory relative to the executing assembly. The module serves as the configuration persistence layer for DAS (Data Acquisition System) hardware, enabling test configurations to survive application restarts.

## 2. Public Interface

### CANConfig Class

**Namespace:** `DTS.DASLib.Service`

| Member | Signature | Description |
|--------|-----------|-------------|
| `Modules` | `Dictionary<string, CANModuleConfig> Modules { get; }` | Read-only accessor for the internal module dictionary, keyed by serial number string. |
| `FileName` | `string FileName { get; }` | Read-only accessor for the full path to the configuration file. |
| `CANConfig()` | Constructor | Default constructor. Initializes an empty configuration with no file association. |
| `CANConfig(string fileName, bool deleteIfPresent)` | Constructor | Loads configuration from `{ExecutingAssemblyLocation}\DASConfigs\{fileName}`. If `deleteIfPresent` is true, deletes existing file; otherwise reads and deserializes it. |
| `SetModule(CANModuleConfig module)` | `void SetModule(CANModuleConfig module)` | Adds a new module or updates an existing one (keyed by `module.SerialNumber`). |
| `GetModule(CANModuleConfig module)` | `CANModuleConfig GetModule(CANModuleConfig module)` | Returns existing module by serial number, or adds the passed module if not found and returns it. |
| `GetSchema()` | `XmlSchema GetSchema()` | Returns `null`. Required by
