 Hideki,

First of all, I've changed the subject title; it's not considered polite to hijack other people's threads.

To your question as to why CAN "is not Specify Loop Type connection", bear in mind that CAN is a broadcast network, not a point-to-point network.  As such, it is somewhat akin to a radio: a node "broadcasts" it's data but doesn't know how many other nodes are listening; it may be 1 or it could be 100.  If some number of those nodes go off-line or become disconnected, the broadcasting node neither knows nor cares.  The only requirement is that there must be at least 1 other node active to acknowledge the transmission.

Regards,
Al Pothoof

Hello

I have a question  about CAN Netowork.
CAN Network is not Specify Loop Type connection.

I want to know why .
I  consider Redundant system of CAN Network.
If the system detect cutting CAN wire, the system connect another CAN wire.

Its system problem is ability of loop connection.
