+Types de registres Modbus et fonctions associées :
+
+1. Coils (Bobines) : sortie digital - light - relay
+   - Fonction Modbus : 01 (FC01)
+   - Lecture : read_coils()
+   - Écriture : write_single_coil() ou write_multiple_coils()
+   - Plage d'adresses typique : 00001-09999
+
+2. Discrete Inputs (Entrées Discrètes) : entrée digital - binary_sensor - switch
+   - Fonction Modbus : 02 (FC02)
+   - Lecture : read_discrete_inputs()
+   - Écriture : Non applicable (lecture seule)
+   - Plage d'adresses typique : 10001-19999
+
+3. Input Registers (Registres d'Entrée) : valeur actuelle  - sensor
+   - Fonction Modbus : 04 (FC04)
+   - Lecture : read_input_registers()
+   - Écriture : Non applicable (lecture seule)
+   - Plage d'adresses typique : 30001-39999
+
+4. Holding Registers (Registres de Maintien) : parameters
+   - Fonction Modbus : 03 (FC03)
+   - Lecture : read_holding_registers()
+   - Écriture : write_single_register() ou write_multiple_registers()
+   - Plage d'adresses typique : 40001-49999
+
+Note : Les adresses Modbus sont souvent spécifiées avec leur 'offset' - c'est-à-dire que l'adresse réelle utilisée dans le protocole est l'adresse spécifiée moins un. Par exemple, l'adresse 40001 serait l'adresse 0 dans le message Modbus.
