matrix - Bus arbitration on CAN bus -


hello have question concerning communication/arbitration on can bus.

say more 1 masters on can bus want send simultaneously means 1 lowest message identifier win arbitration in end , starts send payload. others lose arbitration, switch receiving mode , wait bus free again.

now question:

do masters lost arbitration in previous try arbitrate bus again (i.e. when bus free)? wait next activation cycle defined in can matrix? or can defined in can matrix individually?

thanks in advance, florian

i don't know mean "can matrix", yes bus idle nodes allowed try again on bus starting arbitration process sending start of frame bit , can id.

can not know masters or slaves. called multi-master system. every node has same rights on bus. higher layer can protocols canopen define master roler kind of network management.
