22.1.2 Application
IP16245-1 v1
M12844-3 v4
The IEDs can be equipped with communication devices for line differential
communication (not applicable for RER670) and/or communication of binary
signals between IEDs. The same communication hardware is used for both
purposes.
Sending of binary signals between two IEDs is used in teleprotection schemes and
for direct transfer trips. In addition to this, there are application possibilities, for
example, blocking/enabling functionality in the remote substation, changing setting
group in the remote IED depending on the switching situation in the local
substation and so on.
If equipped with a 64kbit/s LDCM module, the IED can be configured to send
either 192 binary signals or 3 analog and 8 binary signals to a remote IED. If
equipped with a 2Mbps LDCM module, the IED can send 9 analog channels and
192 binary channels to a remote IED.

If it is not possible to have a communication link between each station, the solution
has been to set the protection up in a slave-master-slave configuration. This means
that in Figure
421 , only IED-B has access to all currents and, therefore, this is the
only place where the differential current is evaluated. If the evaluation results in a
trip, the trip signal will be sent over the two communication links.
