If cable diagnostics is enabled in
parameter 12-90 Cable Diagnostic
, the built-in
switch is possible via time domain reflectometry
(TDR). This is a measurement technique which
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 metres with an
accuracy of
±
2 m. The value 0 means no errors
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 a percentage of the total
bandwidth that is allowed for broadcast messages.
Example:
OFF means that the filter is disabled - all broadcast
messages are passed through. The value 0% means
that no broadcast messages are passed through. A
value of 10% means that 10% of the total
bandwidth is allowed for broadcast messages. If
the amount of broadcast messages exceeds the
10% threshold, they are blocked.
12-95 Broadcast Storm Filter
Applies to
parameter 12-94 Broadcast Storm Protection
, if the
broadcast storm protection also includes multicast telegrams.
