Detailed Description

Function Documentation

masterRequestNodeState()

void masterRequestNodeState	(	CO_Data *	d,
		UNS8	nodeId )

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

Definition at line 81 of file nmtMaster.c.

Here is the call graph for this function:

masterSendNMTnodeguard()

UNS8 masterSendNMTnodeguard	(	CO_Data *	d,
		UNS8	nodeId )

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.
