Detailed description2.7 Program operation modeBasic logic functions: Mode group, channel, program operation, reset response (K1)Function Manual, 11/2006, 6FC5397-0BP10-2BA0 1132.7.10.5 A part program section between a Start label and the key word: ENDLABELFunctionalityVia REPEAT in part program block N150, the part program processing branches to the partprogram block N120 that is labeled START_1 with a start label. This part program block andall the part program blocks up to and including the part program block marked with the keyword ENDLABEL (N140) are repeated x number of times. If P is not specified, the partprogram section (N120 - N140) is repeated exactly once. After the last repetition, the partprogram is continued with the part program block N170 following the REPEATinstruction.:N100 ...N120 START_1: ... ; Start label: START__1N130 ...N140 ENDLABEL: ... ; End label: Keyword ENDLABELN150 ...N160 REPEAT START_1 END_1 P=n ; Repetition: START_1 until END_1N170 ...:NoteLabel search directionThe program section marked with the Start and End labels can come before or after theREPEATinstruction. The search initially commences toward the start of the program. If theStart label is not found, a search is made in the direction of the program end.If no keyword ENDLABEL is located between the Start label and the REPEAT instruction, thepart program section from the Start label to the REPEAT instruction is repeated.ProgrammingSyntax: REPEAT [P=n]Label Start label to which the instruction: REPEAT branches.Beginning of the part program section that is repeated.Type: StringP Number of repetitions-{}-n Number of repetitionsType: Integer
