B.3 Node Status Management
Node status management is accomplished via the local node management table, join node management table, and net-
work management table. The following gives a brief description.
B.4 FL-net Local Node Management Table
( 1 ) Basic Function
The FL-net local node management table manages data for local node settings. The following gives a brief description.
• Used for a join request frame or network parameter reading.
• Management data is set from the FL-net upper layer at the startup of the node.
• The node name and the leading address and size of a send area in the common memory can be set from the net-
work.
