18.1.2 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
208 , only IED-B has access to all currents and, therefore, this is the only place
