# DASFactory Interface Documentation

## 1. Purpose  
This module defines a set of C# interfaces that collectively represent the contract for interacting with Data Acquisition Systems (DAS) in the DASFactory subsystem. These interfaces abstract hardware-specific behaviors—such as configuration, diagnostics, real-time data streaming, arming, time synchronization, and communication transport—into a unified API layer. They enable decoupling of core business logic from hardware implementation details, supporting multiple DAS device types (e.g., SLICE, TDAS, g5, S6) and facilitating operations like device discovery, configuration, diagnostics, and data acquisition. The interfaces are designed to be consumed by higher-level services (e.g., `ConfigurationService`, `DiagnosticsService`, `DownloadService`) and are central to the factory pattern used for device management.

## 3. Invariants  
- **`IDASCommunication`** must implement all inherited interfaces (`IConfiguration`, `IDiagnos`, `ITriggerCheck`, `IRealTime`, `IArmStatus`, `IDownload`, `IInformation`, `IAutoArmStatus`, `IAutoArmed`, `IRangeBandwidthLimited`, `ITimeSynchronization`).  
- **`ICommunication`** must support `ConnectString`-based connection establishment and `Execute`/`SyncExecute` for command dispatch.  
- **`ICommunication.CancelEvent`** is a `ManualResetEvent` that signals cancellation state; `Cancel()` and `ForceCancel()` must set this event.  
- **`IDiscoveredDevice`** must accurately reflect physical topology (e.g., `Port`, `PositionOnChain`, `PositionOnDistributor`) for hierarchical devices like SLICE6DB.  
- **`IAnalogInputDASChannel`** must ensure `IsConfigured()` returns `true` only if `SerialNumber` is non-null/non-empty.  
- **`IDASCommunication`** must expose `FirmwareVersion` as read-only, while `SerialNumber` is read-write.  
- **`ITimeSynchronization.SystemBaseTime`** must be valid only if `SupportsTimeSynchronization` is `true`.  
- **`IUDPQATSEntry.Timestamp`** must represent the time the UDP packet was received or generated (implementation-dependent but must be non-null).  
- **`IDASFactory.Refresh(...)`** must update `GetDASList()` to reflect current hardware state before invoking the `action` callback.
