This article explains the mapping between different protocols.

	OUTPUT (Server)
INPUT (Client)	MQTT	BACNET	MODBUS TCP/IP
	LoRaWAN	RW	RW*	RW
	Modbus RTU	RW	RW	R
	M-Bus	R	R	R
	LPB	RW	RW	-
	KNX	RW	R	RW

Device can be used as client, for this please check the mapping below :

	OUTPUT (Server)
INPUT (Client)	MQTT	BACNET	MODBUS TCP/IP
Modbus IP	RW	R	RW
Bacnet IP	RW	-	RW**

* To send a downlink from a BACnet equipment to a LoRaWAN device, the encoding must be UTF-8

** For Modbus TCP/IP Read checked :

Binary Input/Output/Value => Coil/flag
Binary Input/Output/Value => holding register/uint16 and int16
Analog Input/Output/Value => holding register/uint16 and int16
Analog Input/Output/Value => holding register/f32_abcd
Multistate Value/Input/Output => holding register/int16 and uint16

** For Modbus TCP/IP Write checked:

Binary Output <= holding register/uint16 and int16
Analog Output/Value <= holding register/f32_abcd
Analog Output/Value <= holding register/uint16 and int16
Multistate Value/Output <= holding register/int16 and uint16
