19.1.2 Functionality
The remote end data communication is used either for the transmission of current
values with a maximum of 8 binary signals in the line differential protection IED, or
for the transmission of only binary signals (up to 192) in the other IEDs. The binary
signals are freely configurable and can, thus, be used for any purpose, for example,
communication scheme related signals, transfer trip and/or other binary signals
between IEDs.
Communication between two IEDs requires that each IED is equipped with a Line
Data Communication Module (LCDM). The LDCMs then act as interfaces to a 64
kbit/s communication channel for duplex communication between the IEDs.
The IED can be equipped with up to two short range or medium range LDCMs.
