SliceSimpleArm

1. Purpose

This module defines the core command and response enumerations used for communication with a SliceSimpleArm (SSA) subsystem—likely a hardware control interface for a data acquisition or sensor system. It establishes a standardized protocol vocabulary: SSACommand enumerates the set of actionable operations that can be sent to the device (e.g., arming, starting recording, diagnostics), while SSAResponse enumerates the structured responses the device may return, including success/failure states and specific error conditions (e.g., NoSensorsFound, DiagnosticsFailedOffsetTolerance). This enables type-safe, consistent messaging between software layers interacting with the SSA hardware.

2. Public Interface

The module exposes only two public enums; no classes, methods, or properties are defined.

• SSACommand
  Type: enum
  Values:

  • ConfigureDevice – Request device configuration.
  • Diagnostics – Trigger internal self-diagnostics.
  • Arm – Prepare the device for data acquisition (e.g., enable sensors, set state to armed).
  • StartRecord – Begin recording data.
  • CheckForArmed – Query whether the device is currently armed.
  • Disarm – Deactivate the armed state (e.g., disable sensors, reset state).
  • Download – Request data or logs from the device.
  • SetLowPowerMode – Transition the device into a low-power state.
  • Trigger – Initiate an external or software-triggered event.

• SSAResponse
  Type: enum
  Values:

  • Unknown – Default/uninitialized response.
  • Status – General status update (non-specific).
  • Pass – Command executed successfully.
  • Fail – Command failed for an unspecified reason.
  • SystemNotArmed – Operation requires the system to be armed (e.g., StartRecord), but it is not.
  • NoSensorsFound – No sensors detected during configuration/diagnostics.
  • NoEIDsFound – No Event Identifiers (EIDs) found—likely in configuration or metadata.
  • UnknownEIDFound – An unrecognized EID was encountered.
  • NoDASConnected – Data Acquisition System (DAS) is not connected or detected.
  • ExceptionThrown – An unexpected exception occurred during command processing.
  • DiagnosticsFailedOffsetTolerance – Diagnostics failed due to sensor offset exceeding tolerance.
  • DiagnosticsFailedShuntCheck – Diagnostics failed during shunt calibration check.

3. Invariants

• SSACommand and SSAResponse are mutually independent enums; no implicit mapping between command and response values is defined here (e.g., Arm does not imply a specific response value).
• All enum values are explicitly named and non-numeric; no implicit integer values are relied upon in this file.
• No runtime validation or enforcement of command/response semantics is present in this module—validation logic (if any) resides elsewhere.
• The Unknown value in both enums likely serves as a sentinel for uninitialized or unparseable states.

4. Dependencies

• No external dependencies are declared in this file (no using statements beyond namespace scope).
• This module is part of DTS.Common.Enums.SliceSimpleArm, implying it is consumed by higher-level modules (e.g., communication layers, device drivers, UI) in the DTS.Common assembly or dependent projects.
• Likely consumers include:
  • Device communication handlers (e.g., serial/USB/I²C drivers) that serialize/deserialize SSACommand/SSAResponse values.
  • State machines or controllers managing the armed/disarmed lifecycle.
  • Diagnostic or logging utilities that interpret SSAResponse codes.

5. Gotchas

• Ambiguity in command semantics: The enum names (e.g., Trigger, Download) do not specify how or when they should be used (e.g., is Trigger synchronous? Does Download require prior CheckForArmed?). These rules are not defined here.
• No versioning or extensibility guidance: Adding new commands/responses may break backward compatibility if serialized representations (e.g., over a wire protocol) are assumed fixed.
• Status vs. Pass: The distinction between Status (generic update) and Pass (explicit success) is unclear—consumers may conflate them.
• UnknownEIDFound vs. NoEIDsFound: The difference between these two responses is not documented—consumers must infer whether NoEIDsFound implies zero EIDs were expected/required, while UnknownEIDFound implies unexpected EIDs were present.
• No error hierarchy: All failures are flat; no grouping (e.g., "configuration errors", "hardware errors") is provided, potentially complicating error handling.
• None identified from source alone.
