Function blocks6.2 Interrupt function blocksIf an output is defined as a physical output on base device in the parameters for theinterrupt program, the output will be assigned an identifier of QP01 – QP04 and will actdirectly on device output Q1 – Q4.Zur Verarbeitung des Interrupt-Programmes hat der Funktionsbaustein einen eigenenMerkerbereich von 32 Merker-Bits.Available functions within an interrupt programInterrupt programs are not available when using the EDP programming language.Action KOP FBS STNew network √ √ √Input/output inverter √ √ √Contacts Make, Break, Constant 1, Constant 0Coils Contactor, Negated contactor, Set, ResetJump functions Jump if 1, Jump if 0, Return if 1, Return if 0Logic gates AND, AND NOT, OR, OR NOT, XOR, XNORConditional statement – – √Simple alternative – – √Multiple alternatives – – √6.2.1.3 The function block and its parametersFunction block inputsDescription Note(Bit)EN 1: Activates the function block.
