• PULSETIMER function block can be used, for example, for pulse extensions orlimiting of operation of outputs, settable pulse time.• GATE function block is used for whether or not a signal should be able to passfrom the input to the output.• XOR function block. Each block has two outputs where one is inverted.• LOOPDELAY function block used to delay the output signal one executioncycle.• TIMERSET function has pick-up and drop-out delayed outputs related to theinput signal. The timer has a settable time delay and must be On for the inputsignal to activate the output with the appropriate time delay.• AND function block. Each block has four inputs and two outputs where one isinverted• SRMEMORY function block is a flip-flop that can set or reset an output fromtwo inputs respectively. Each block has two outputs where one is inverted. Thememory setting controls if the block's output should reset or return to the state itwas, after a power interruption. The SET input has priority if both SET andRESET inputs are operated simultaneously.• RSMEMORY function block is a flip-flop that can reset or set an output fromtwo inputs respectively. Each block has two outputs where one is inverted. Thememory setting controls if the block's output should reset or return to the state itwas, after a power interruption. The RESET input has priority if both SET andRESET are operated simultaneously.Configurable logic Q/TA number of logic blocks and timers, with the capability to propagate timestamp andquality of the input signals, are available. The function blocks assist the user to adaptthe IEDs configuration to the specific application needs.• ORQT OR function block that also propagates timestamp and quality of inputsignals. Each block has six inputs and two outputs where one is inverted.• INVERTERQT function block that inverts the input signal and propagatestimestamp and quality of input signal.• PULSETIMERQT Pulse timer function block can be used, for example, forpulse extensions or limiting of operation of outputs. The function also propagatestimestamp and quality of input signal.Section 13 1MRK 504 135-UEN ALogic378Technical manual
