Programmer Operation2604 Controller4.5.2. Go Back SegmentGo Back allows segments in a program to be repeated by a set number of times. It is theequivalent of inserting ‘sub-programs’ on some controllers. Figure 4-4 shows an example of aprogram which is required to repeat the same section a number of times and then continue theprogram.A Go Back segment is used to save the total number of segments required in a program and tosimplify setting up. When planning a program it is advisable to ensure that the end and startsetpoints of the program are the same otherwise it will step to the different levels. A Go Backsegment is defined when editing a program.PVThis section is repeated ‘n’ timesSegment 6 isdefined as a GoBack segmentAt this point Go Back to segment 3Time→Segment 1 Segment 2 Segments 3 to 6Segment 7Figure 4-4: An Example of a Program with Repeating Section4.5.3. End SegmentThe last segment in a program is normally defined as an End segmentThe program either ends, repeats or resets in this segment. You specify which is the casewhen you create, or modify, the program. When the program ends, the programmer is put intoeither, a continuous dwell state with all outputs staying unchanged, or the reset state.4.6.
