* @file main.cpp
|
|
* @brief Main execution program for the CRAH Unit (TCP) Emulator.
|
|
* @author Emmanuel Hernandez Cruz
|
|
* @date 2025-09-02
|
|
*
|
|
* @details This file contains the main execution program for an Arduino-based emulator of a CRAH unit.
|
|
* The program uses a Wi-Fi connection to communicate via the Modbus IP protocol.
|
|
*
|
|
* The setup() function initializes the following:
|
|
* - Serial communication for debugging.
|
|
* - Wi-Fi connection using credentials from config.h.
|
|
* - A Modbus TCP server.
|
|
* - Modbus points (Coils, Holding Registers, etc.) based on a predefined map in config.h.
|
|
*
|
|
* The loop() function continuously:
|
|
* - Services the Modbus TCP server to handle incoming requests.
|
|
* - Periodically calls the main update loop for the emulated equipment, which
|
|
* manages state transitions and behavior strategies.
|
|
*
|
|
* @see config.h for Wi-Fi and Modbus configuration.
|
|
* @see Equipment.h for the main equipment logic.
|
|
* @see State.h for different equipment states.
|
|
* @see Strategies/Strategy_Behavior.h for value generation strategies.
|
|
* @see Modbus_Point.h for the base class for all Modbus points.
