Participating Node Management Table
The node status of each node joining in the network is monitored by the
management table held by each node. Regarding the nodes joining the network,
this table handles the data to be managed for each node.
1 At a start, participating node management table and the network
management table is created in accordance with the received token frame.
2 Upon receipt of each token frame, each node updates the participating node
management table.
3 Upon receipt of the participation request frame for new joining, the joining
node management table is updated.
4 When non-reception of a token frame of each node or a timeout is detected 3
times running, the corresponding node is deleted from the table.
