FC 300 Programming Guide
12-89 Transparent Socket Channel Port
Range:
0* [0 – 9999]
3.13.6 12-9* Advanced Ethernet Settings
12-90 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. 12-10,
12-91 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.
12-92 IGMP Snooping
Option:
[0] Disable
[1] * Enable
12-93 Cable Error Length
Option:
[0] Error length Port 1 (0 – 200m)
[1] Error length Port 2 (0 – 200m)
12-94 Broadcast Storm Protection
Option:
Function:
Configures the TCP port-number for the transparent socket channel. This enables FC-telegrams to
be sent transparently on Ethernet via TCP. Default value is 4000, 0 means disabled.
Function:
Enables/disables advanced Cable diagnosis function. If enabled, the distance to cable errors can be
read out in par. 12-93. 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. 12-90, the built-in switch is able via Time Domain Reflec-
tometry (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 dis-
tance 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
packages, which can use up network resources. The value indicates a percentage of the total band-
width that is allowed for broadcast messages.
