ETHERNET NCIT
Physical Link Copper Copper / Fibre Optic
This cell defines whether an electrical connection (“Copper” selection) or fiber optic
connection is being used for communication.
AntiAlias Filter Disabled Disabled / Enabled
This cell activates or deactivates the anti-aliasing filter.
Merge unit Delay 0 s 0 to 3.000ms, in steps of 250.0µs
This cell adjusts the maximum time-delay starting at the reception of the Ethernet message
from the “first” Merging Units (MU) to the reception of the Ethernet message from the “last”
Merging Units (MU). This time-delay should be adjusted to receive the messages from all
the MUs on time. The signal processing will start at the end of the Merge Unit delay. If a
message is not received in that specified time, a synchronisation alarm will appear.

This cell is used to select the logical node arrangement.
LN1 Name MiCOM Logical Node 1
LN2 Name MiCOM Logical Node 2
LN3 Name MiCOM Logical Node 3
LN4 Name MiCOM Logical Node 4
Name of the Logical Nodes LN1 to LN4, to identify it (up to 34 characters).
Note: It is important for each Logical Node name to be exactly the same as the one set in
the Merging Unit that broadcasts it.
Synchro Alarm No Sync clk
‘No Sync clk’ / ‘Global 1 PPS’ /
‘Local 1 PPS’
Lost of the synchronization alarm in accordance with the following values.
‘Global 1 PPS’ = the Sample Values (SV) are synchronized with a global area clock
(GPS like clock).
‘Local 1 PPS’ = the SV are synchronized with a local area clock signal (substation).
No Sync clk’ = the SV are not synchronized with an external clock signal (internal
synchronization).
