6.4.3.2. Go Back Segment
Go Back allows segments in a program to be repeated by a set number of times. It is the
equivalent of inserting ‘sub-programs’ on some controllers. Figure 6-2 shows an example of
a program which is required to repeat the same section a number of times and then continue
the program.
A Go Back segment is used to save the total number of segments required in a program and
to simplify setting up. When planning a program it is advisable to ensure that the end and
start setpoints of the program are the same otherwise it will step to the different levels. A Go
Back segment. is defined when editing a program, see section 6.7.4.
This section is repeated ‘n’ times
Segment 6 is
defined as a Go
Back segment
At this point Go Back to segment 3
Segment 1 Segment 2 Segments 3 to 6
Segment 7

6.4.3.3. End Segment
The last segment in a program is normally defined as an End segment
The program either ends, repeats or resets in this segment. You specify which is the case
when you create, or modify, the program. When the program ends, the programmer is put
into either, a continuous dwell state with all outputs staying unchanged, or the reset state.
