Constants

Path: src/modbus/constants.h

Revision History: Initial documentation

This file defines global constants used throughout the application, particularly for component management and debug settings.

REQUIREMENTS

No specific hardware requirements. This is a header-only file that provides constant values.

PROVIDES

• Global constant definitions:
  • MAX_COMPONENTS: Maximum number of components in the system
  • DEFAULT_DEBUG_INTERVAL: Default interval for debug operations in milliseconds

FEATURES

• Defines system-wide constants for configuration
• Sets limits for component management
• Establishes default timing values

DEPENDENCIES

None. This is a standalone header file.

BEHAVIOUR

This component doesn't have behavior as it only provides constant definitions.

TODOS

PERFORMANCE

• Consider evaluating if MAX_COMPONENTS is appropriately sized for the application's needs
• Review if any constants should be configurable at compile time based on target hardware

SECURITY

• No direct security concerns as these are compile-time constants

COMPLIANCE

• Ensure constant values comply with any relevant industrial standards or specifications
• Consider documenting the reasoning behind specific values for future reference

RECOMMENDATIONS

• Use these constants throughout the application rather than hard-coding values
• Consider moving to a more structured configuration system if the number of constants grows substantially
• Document the impact of changing these values on system behavior and resource usage
