distance to cable errors can be read out in
parameter 12-93 Cable
Error Length
. The parameter resumes to the default setting of
disable after the diagnostics have finished.
Option:
Function:

[0 - 65535 ]
If cable diagnostics is enabled in
parameter 12-90 Cable Diagnostic
,
the built-in switch is possible via
time domain reflectometry (TDR).
This measurement technique
detects common cabling problems
such as open circuits, short circuits,
and impedance mismatches or
breaks in transmission cables. The
distance from the option to the
error is shown in meters with an
accuracy of
±
2 m (6.56 ft). The
value 0 means that no errors are
detected.
12-94 Broadcast Storm Protection
Range:
Function:
-1 %
*
[-1 - 20 %]
The built-in switch is capable of
protecting the switch system from
receiving too many broadcast
packages, which can use up
network resources. The value
indicates the percentage of the
total bandwidth that is allowed for
broadcast messages.
Example:
OFF means that the filter is
disabled: All broadcast messages
pass through. The value 0% means
that no broadcast messages pass
through. A value of 10% means
that 10% of the total bandwidth is
allowed for broadcast messages. If
the number of broadcast messages
increases above the 10% threshold,
they are blocked.
12-95 Inactivity timeout
Range:
Function:

*
[0 - 3600]
12-96 Port Config
