3.4.1 Step Sequence Configuration
A step sequence program consists of the following elements:
Step
A step is a unit of processing in a program.
• A step number [Sn] necessary to control execution and a
subprogram [Pm] that describes actual processing are defined for
a step.
• Each step is always assigned with a step number. A duplicate
step number cannot be used in a program.
• A step can be in any one of three logical states: running, stopping,
and stopped. The running state is also called an active state. The
stopping and stopped states are collectively referred to as
inactive states.
