Communications Enabled
state until a Virtual Network (VN) that it supports becomes
active, or until a time period elapses where no VNs have been activated.
Note:
Refer to GMW3104 for more information on Virtual Network Management Frames.
If a VN that a node supports becomes active, then the device transitions to the
Communications Active
state.
A node transitions to the
ECU Ready
state if a timeout occurs.
Note:
GMW3104 also specifies additional requirements of the application before an ECU can transition to the
ECU_READY state.
5.2.3 Communications Active (COMM_ACTIVE) State.
The state of a node when it is participating in at least
one active VN. The node may have either internally decided to activate a VN or it may have received a Virtual
Network Management Frame (VNMF) with an activation request for a VN the node supports. The
Communication Active state is entered before any frame can be transmitted.
Note:
Refer to GMW3104 for more information on Virtual Network Management Frames.
A node remains in this state as long as it has at least one active VN. This VN can be an initially active VN, an
application triggered VN, or a bus activated VN. Once a node has no VNs active, it can transition to the
Communication Enabled
state.
A node shall be capable of receiving, processing, and responding to diagnostic messages in this state any time
the
initially active diagnostic VN
is active or the
application triggered diagnostic VN
is active.
