10-1 Controller Link Network Diagnostic Tool
10-1-4 Diagnosing Disconnections
Disconnection Counters
Disconnection counters, which measure disconnections at each node, can be
displayed by diagnosing disconnections.
Displaying Disconnection Counters
Select Diagnose – Display disconnection counter from the Main Menu.
Disconnection Counter Display
• The disconnection counters that measure disconnections at each node are
displayed.
• The following counter items are displayed.
Time of beginning
disconnection data recording
Number of node/network
separations
Number of network
disconnections
Number of local node
disconnections
Maximum number of
consecutive disconnect cycles
Number of frame drop-outs
(SL1, SL2)
Number of frame brakes
detected (SL1, SL2)
Number of CRC errors
detected (SL1, SL2)
• Click the Copy Button to copy the data for the disconnection counters to the
clipboard. The data on the clipboard will be in CSV (text) format.
• The data on the clipboard can be pasted to an editor, word processor, or
10-16
Item
Displays the time that recording disconnection information was
started. This will be the time the power supply was turned ON to
the node, the time the Unit at the node was restarted, or the
time the disconnection counters were cleared.
Displays the number of times the local node was separated from
the network.
Displays the number of disconnections detected on the network.
Displays the number of disconnections detected for the local
node.
Displays the number of communications cycles over which a
disconnection continued. Use this information to determine if a
disconnection was momentary or continuous.
Displays the number of times a data frame received at another
communications port was not received at all at the local
communications port.
Dropouts are counted when the communications line is
completely disconnected.
Displays the number of times only a carrier was detected at the
local communications port for a data frame received at another
communications port.
Brakes are counted when the optical cable is damaged, when
end surface processing is faulty, for contact faults, or whenever
else transmissions are unstable.
Displays the number of CRC errors and Manchester errors.
These errors are counted when the optical cable is damaged,
when end surface processing is faulty, for contact faults, or
whenever else transmissions are unstable.
