5.5 Types of Sequences
Single Sequence: The basic type of sequence
The first step in a step ladder diagram is called initial step, ranged as S0 ~ S9. The steps following
the initial step are general steps numbered as S10 ~ S1023. When IST instruction is applied, S10 ~
S19 will become the steps for zero return operation.
1. Single Sequence without Divergence and Convergence
After a sequence is completed, the control power on the steps will be transferred to the initial
step.
