INFORMATION:
Communication between two IEDs requires that eachIED is equipped with a Line Data Communication Module(LDCM). The LDCM then acts as an interface to 64 kbit/sand 2Mbit/s communication channels for duplexcommunication between the IEDs. In 2Mbit/s mode,each LDCM can send and receive up to 9 analog and upto 192 binary signals simultaneously. In 64kbit/s mode,the LDCM can be configured to work in either analogmode or binary mode. In analog mode, the IED can sendand receive up to 3 analog signals and up to 8 binarysignals. In binary mode, the LDCM can send and receiveonly binary data (up to 192 binary signals).
