• OR function block. Each block has up to six inputs and two outputs where one isinverted.• PULSETIMER function block can be used, for example, for pulse extensions orlimiting of operation of outputs, settable pulse time.• 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, after a power interruption, the flip-flop resets orreturns to the state it had before the power interruption. RESET input has priority.• 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, after a power interruption, the flip-flop resets orreturns to the state it had before the power interruption. The SET input haspriority.• TIMERSET function has pick-up and drop-out delayed outputs related to theinput signal. The timer has a settable time delay.• XOR function block. Each block has two outputs where one is inverted.15.6.1 AND function block ANDThe AND function is used to form general combinatory expressions with booleanvariables. The AND function block has up to four inputs and two outputs.
