Chapter 15: Appendix
(2)Leaving an FL-net network
Each node checks the node numbers each time it receives a token frame. If the JW-50FL does not receive a token frame from a certain node three times in a row, the node is regarded as having left the network.
(This is also true when the node holding the token does not send the token after token monitor time has elapsed.)
If the JW-50FL determines that a node has left the network, it deletes that node's number from the management table.
