# Documentation: `DTS.Common.Interface.DASFactory.Config` Interfaces

## 1. Purpose

This module defines a set of interfaces that collectively represent the configuration, metadata, and operational state of a Data Acquisition System (DAS) unit. These interfaces serve as the contract layer between the DAS hardware abstraction and higher-level services (e.g., `ConfigurationService`), enabling structured configuration management, serialization, channel/module metadata retrieval, and system-wide state introspection. They are used primarily during setup, pre-test configuration, and post-test data analysis to expose hardware capabilities, channel configurations, calibration data, and synchronization settings in a type-safe and testable manner.

## 3. Invariants

- **Channel numbering**: `IDASChannel.Number` is a 0-based absolute channel index within the DAS (0..29 implied by `MapDASChannelNumber2*` methods).
- **Module indexing**: `IDASModule.ModuleArrayIndex` is 0-based and corresponds to position in `IConfigurationData.Modules` and `IInfoResult.Modules`.
- **Channel mapping consistency**: The mapping functions in `IInfoResult` must be consistent and invertible (e.g., `MapModuleArrayIndexAndChannelNum2DASChannel` is the inverse of `MapDASChannelNumber2ModuleArrayIndex` and `MapDASChannelNumber2ModuleChannelNumber`).
- **`IsConfigured()` semantics**: A channel is considered "configured" only if a sensor is connected and/or configuration data exists (set via `ConfigurationService.Configure(...)`).
- **`DASInfo` initialization**: `IInformation.DASInfo` must be set before calling `SetDASInfo(...)`; otherwise, behavior is undefined.
- **`NumberOfDownloadChannels()` excludes UART/StreamOut**: Only channels capable of data download (e.g., analog inputs) are counted.
- **`CalibrationDate` invalidity**: A value of `1970-01-01` indicates invalid/NA calibration date (per `IInfoResult.CalibrationDate` documentation).
- **`DisplayOrder` arrays**: `DisplayOrder` (per-channel) and `DasDisplayOrder
