NMT Master
[Network Management]

Ask the state of the slave node whose nodeId is node Id.

To ask states of all nodes on the network (NMT broadcast), nodeId must be equal to 0

Parameters:

*d	Pointer to a CAN object data structure
nodeId	Id of the slave node
d
nodeId

Returns:

Transmit a NodeGuard message on the network to the slave whose nodeId is node ID.

Parameters:

*d	Pointer to a CAN object data structure
nodeId	Id of the slave node

Returns:

• 0 is returned if the NodeGuard message was send.
• 1 is returned if an error occurs.

Parameters:

d
nodeId

Returns:

Transmit a NMT message on the network to the slave whose nodeId is node ID.

Parameters:

*d	Pointer to a CAN object data structure
nodeId	Id of the slave node
cs	The order of state changement

Allowed states :

• cs = NMT_Start_Node // Put the node in operational mode
• cs = NMT_Stop_Node // Put the node in stopped mode
• cs = NMT_Enter_PreOperational // Put the node in pre_operational mode
• cs = NMT_Reset_Node // Put the node in initialization mode
• cs = NMT_Reset_Comunication // Put the node in initialization mode

The mode is changed according to the slave state machine mode :

• initialisation ---> pre-operational (Automatic transition)
• pre-operational <--> operational
• pre-operational <--> stopped
• pre-operational, operational, stopped -> initialisation
  
  

  Returns:

  errorcode

  • 0 if the NMT message was send
  • 1 if an error occurs

  Parameters:

  d
  Node_ID
  cs

  Returns:
