* - Serial communication for debugging.
* - Wi-Fi connection using credentials from config.h.
* - A Modbus IP server.
* - 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 IP server.
* - Reads values from the Modbus server into internal data structures.
* - Updates the state of the emulated equipment.
* - Writes updated values back to the Modbus server.
* - 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.
