The AND function block has four inputs and two outputs.Default value on all four inputs are logical 1 which makes it possible for the user to justuse the required number of inputs and leave the rest un-connected. The output OUT hasa default value 0 initially, which suppresses one cycle pulse if the function has been put inthe wrong execution order.Function blockANDINPUT1INPUT2INPUT3INPUT4OUTNOUTIEC09000289-1-en.vsdIEC09000289 V1 ENFigure 269: AND function blockSignalsTable 392:AND Input signalsName Type Default DescriptionINPUT1 BOOLEAN 1 Input signal 1INPUT2 BOOLEAN 1 Input signal 2INPUT3 BOOLEAN 1 Input signal 3INPUT4 BOOLEAN 1 Input signal 41MRK 506 335-UUS A Section 13Logic551Technical manual
