	)

Parameters:

	d
	m

Notice that only the master can have sent this node guarding request

Receiving a NMT NodeGuarding (request of the state by the master) Only answer to the NMT NodeGuarding request, the master is not checked (not implemented)

send the nodeguard response.

Not a request CAN

the slave's state receievd is stored in the NMTable

The state is stored on 7 bit

Boot-Up frame reception

The device send the boot-up message (Initialisation) to indicate the master that it is entered in pre_operational mode Because the device enter automaticaly in pre_operational mode, the pre_operational mode is stored NMTable[bus_id][nodeId] = Pre_operational
