EN-89 Transparent Socket Channel Port
Range:
0* [0 – 9999]
EN-90 Cable Diagnostics
Option:
[0] * Disable
[1] Enable
NB!
The cable diagnostics function will only be issued on ports where there is no link (see par. EN-10, Link Status)
EN-91 Auto Cross-Over
Option:
[0] Disable
[1] * Enable
NB!
Disabling of the auto cross-over function will require crossed Ethernet cables for daisy-chaining the options.
EN-92 IGMP Snooping
Option:
[0] Disable
[1] * Enable
EN-93 Cable Error Length
Option:
[0] Error length Port 1 (0 – 200m)
[1] Error length Port 2 (0 – 200m)
EN-94 Broadcast Storm Protection
Option:
[0] Protection Value Port 1 (*Off – 20%)
[1] Protection Value Port 2 (*Off – 20%)
Function:
Configures the TCP port-number for the transparent socket channel. This enables Drive-messages to be
sent transparently on Ethernet via TCP. Default value is 0, 0 means disabled.
Function:
Enables/disables advanced Cable diagnosis function. If enabled, the distance to cable errors can be read
out in par. EN-93. The parameter resumes to the default setting of Disable after the diagnostics have
finished.
Function:
Disables the auto cross-over function.
Enables the auto cross-over function.
Function:
This prevents flooding of the Ethernet protocol stack by only forwarding multicast packets to ports that
are a member of the multicast group
Disables the IGMP snooping function.
Enables the IGMP snooping function.
Function:
If Cable Diagnostics is enabled in par. EN-90, the built-in switch is able 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 displayed in meters with an accuracy of +/- 2m. The value 0 means no errors detected.
Function:
The built-in switch is capable of protecting the switch system from receiving too many broadcast pack-
ages, which can use up network resources. The value indicates a percentage of the total bandwidth that
is allowed for broadcast messages.
Example:
The "OFF" means that the filter is disabled –all broadcast messages will be passed through. The value
"0%" means that no broadcast messages will be passed through. A value of "10%" means that 10% of
the total bandwidth is allowed for broadcast messages, if the amount of broadcast messages increases
above the 10% threshold, they will be blocked.
