UNS32 OnCOB_ID_SyncUpdate	(	CO_Data *	d,
		const indextable *	unsused_indextable,
		UNS8	unsused_bSubindex
	)

This is called when Index 0x1005 is updated.

Parameters:

	d
	unsused_indextable
	unsused_bSubindex

Returns:

Here is the call graph for this function:

UNS8 proceedSYNC	(	CO_Data *	d,
		Message *	m
	)

Parameters:

	d
	m

Returns:

pointer to the var which is mapped to a pdo

pointer fo the var which holds the mapping parameter of an mapping entry

pointer to the transmissiontype...

only operational state allows PDO transmission

So, the node is in operational state

study all PDO stored in the objects dictionary

get the PDO transmission type

check if transmission type is after (this) SYNC

The message may not be transmited every SYNC but every n SYNC

get PDO CobId

get mapped objects number to transmit with this PDO

get mapping parameters

get data to transmit

copy bit per bit in little endian

loop to get all the data to transmit
