(2) Normal step
A normal step represents one process in the SFC program. A normal step may be in the active or inactive state. When a normal
step is in the active state, it executes actions according to the control of the action qualifiers.
Notes:
Actions “A002,” “A005,” and “A006
are executed when the step is active.
As shown in the above figure, one step may be assigned two or more actions. There is no limit to the number of actions that
can be assigned to one step.
Notes:
The state of a step is represented by its status. For example, the flag of “S002” in the above figure is described as “S002.X.”
(3) Jump
A jump is a step whose next sequential step is the destination of the jump within the same worksheet or on another worksheet in
the same POU. Execution never jumps into another POU. No action can be assigned to a jump.
Destination of jump
The jump name must be the
name of the destination step.
