4.5 Types of Sequences
Single Sequence: The basic type of sequences
The first step in a step ladder diagram is called the initial step, which can be S0 ~ S9. The steps following the
initial step are general steps, which can be S10 ~ S1023. If you are using IST instruction, S10 ~ S19 will become the
steps for zero return.
a) Single sequence without divergence and convergence
After a sequence is completed, the control power on the steps will be given to the initial step.
