ChannelMode defines how an IED discards the LDCM information when one of the IEDs in the
system is out of service: it can either be done on the IED out of service by setting all local
LDCMs to channel mode
OutOfService or at the remote end by setting the corresponding
LDCM to channel mode
Blocked. If OutOfService is selected, the IED should have active
communication to the remote end during the whole maintenance process, that is, no restart or
removal of the fiber can be done.
This setting does not apply to two-end communication.
Blocked
IED does not use data from the LDCM
OutOfService
IED informs the remote end that it is out of service
TerminalNo is used to assign a unique address to each LDCM in all current differential IEDs. Up
to 256 LDCMs can be assigned a unique number. For example, in a local IED with two LDCMs:
•
LDCM for slot 305: set
TerminalNo to 1 and RemoteTermNo to 2
•
LDCM for slot 306: set
TerminalNo to 3 and RemoteTermNo to 4
In multiterminal current differential applications,with 4 LDCMs in each IED, up to 20 unique
addresses must be set.
A unique address is necessary to give high security against incorrect
addressing in the communication system. If the same number is used for
TerminalNo in some of the LDCMs, a loop-back test in the communication
system can give an incorrect trip.
RemoteTermNo is used to assign a number to each related LDCM in the remote IED. For each
LDCM,
RemoteTermNo is set to a different value than TerminalNo, but equal to the TerminalNo
of the remote end LDCM. In the remote IED,
TerminalNo and RemoteTermNo are reversed as
