C-5
Network diagnostics allow you to check the node number of the 4010, the
network topology, and network attendance.
Figure C-2 shows a typical Network Topology screen. Topology information
shows how the network is physically wired and whether there are any breaks in
the network loop.
Figure C-2. Network Topology Screen
Attendance information shows if the network nodes are configured. Each
position on the 4010’s LCD represents a node’s address for a maximum of 80
nodes (only 80 nodes can be displayed because there are only 80 positions on
the 2 by 40 character LCD). Each node can only be represented by one
character. Figure C-3 is NOT a typical Attendance screen, it is shown for
reference only.
