5-270 L90 Line Current Differential System GE Multilin5.8 INPUTS/OUTPUTS 5 SETTINGS5On the two-terminal, two channel system (redundant channel), direct outputs 1-1 to 1-8 are send over both chan-nels simultaneously and are received separately as direct inputs 1-1 to 1-8 at channel 1 and direct inputs 2-1 to 2-8at channel 2. Therefore, to take advantage of redundancy, the respective operands from channel 1 and 2 can beORed with FlexLogic™ or mapped separately.b) DIRECT INPUTSPATH: SETTINGS ÖØ INPUTS/OUTPUTS ÖØ DIRECT Ö DIRECT INPUTSThe DIRECT INPUT 1-1(8) DEFAULT setting selects the logic state of this particular bit used for this point if the local relay hasjust completed startup or the local communications channel is declared to have failed. Setting DIRECT INPUT 1-1(8) DEFAULTto “On” means that the corresponding local FlexLogic™ operand ( DIRECT I/P 1-1(8) ) will have logic state “1” on relay startupor during communications channel failure. When the channel is restored, the operand logic state reflects the actual state ofthe corresponding remote direct output.c) DIRECT OUTPUTSPATH: SETTINGS Ø INPUTS/OUTPUTS ÖØ DIRECT ÖØ DIRECT OUTPUTSThe relay provides eight direct outputs that are conveyed on communications channel 1 (numbered 1-1 through 1-8) andeight direct outputs that are conveyed on communications channel 2 (numbered 2-1 through 2-8). Each digital point in themessage must be programmed to carry the state of a specific FlexLogic™ operand. The setting above is used to select theoperand which represents a specific function (as selected by the user) to be transmitted.
