Disconnection Counter Display
•
The disconnection counters that measure disconnections at each node are
displayed.
•
The following counter items are displayed.
Item
Description
Time of beginning
disconnection data recording
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.
Number of node/network
separations
Displays the number of times the local node was separated from
the network.
Number of network
disconnections
Displays the number of disconnections detected on the network.
Number of local node
disconnections
Displays the number of disconnections detected for the local
node.
Maximum number of
consecutive disconnect cycles
Displays the number of communications cycles over which a
disconnection continued. Use this information to determine if a
disconnection was momentary or continuous.
Number of frame drop-outs
(SL1, SL2)
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.
Number of frame brakes
detected (SL1, SL2)
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.
Number of CRC errors
detected (SL1, SL2)
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.
