Function description
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.
