13.3 Configurable logic blocks13.3.1 Standard configurable logic blocks13.3.1.1 FunctionalityA number of logic blocks and timers are available for the user to adapt theconfiguration to the specific application needs.• OR function block.• INVERTER function blocks that inverts the input signal.• 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.• LOOPDELAY function block used to delay the output signal one execution cycle.• TIMERSET function has pick-up and drop-out delayed outputs related to theinput signal. The timer has a settable time delay and must be Enabled for the inputsignal to activate the output with the appropriate time delay.• AND function block.• SRMEMORY function block is a flip-flop that can set or reset an output from twoinputs 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 from twoinputs 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.Section 13 1MRK 502 043-UUS BLogic368Technical Manual
