In-Depth Information
Each network node monitors the transmission and reception of relevant mes-
sages; this and additional information are used as input to an error state machine.
For example, if an expected message is not transmitted or received, a corresponding
message status counter (MSC) is incremented. If any MSC reaches a predefined
limit, an error is flagged and an appropriate action is taken. In this case, the node is
reconfigured and attempts to rejoin the network; see Fig.
5.5
for an overview of the
TTCAN error state machine.
