granted when requested at that node. Node 2 continues to hold control since it is still
connected to nodes 1,3 and 4.
Scenario 6: Disconnected node is currently in control
• 5-Node system
• Node 5 is in control
• Node 2 gets disconnected - refer to the Figure A group of nodes in degraded
mode and one node in standalone mode of operation above
When Node 5 gets disconnected, nodes 1,2,3 and 4 are still in a network and none of them
is in control. Therefore, control will be granted on first come, first serve basis. Node 5 begins
to operate in a standalone mode and continues to hold control.
Scenario 7: Network heals
• 5-Node system
• Node 2 gets disconnected - refer to the Figure A group of nodes in degraded
mode and one node in standalone mode of operation above
• Node 5 gets reconnected
When Node 5 gets disconnected, nodes 1,2,3 and 4 are still in a network and none of them
is in control. Therefore, control will be granted on first come, first serve basis. Node 5 begins
to operate in a standalone mode. If the connection between Node 5 and the rest of the
network is restored, all the nodes (if any) which were previously in control will automatically
lose it, even if there is only one node in control of the healed network. All nodes will be put
into idle state. Control will be granted on first come, first serve basis.
The current mode of operation of a node is indicated by an LED. Such LED can be
configured on a 48 LED adder with Type=Node Status, Assignment=Node ModeOfOperation
and a correlation to the local node.
