Assigning a step transition to a sequence 4.9.5.
To assign step transition to the sequence:
1.
Assign the Init jump to the Start_Sequence step in SFC. Figure 4.9.5-1 shows the
program editor after the Start_Sequence and End_Sequence steps with the Ini-
tial_Transition objects have been set.

2. Right-click the Initial_Transition object and select Insert step-transition after to
add step 1 in Sequence SFC.
3. Rename the added step to Step 1 by editing the Name parameter in the properties
view. Also assign a Step1_Action action object for the added step by editing the
Main Entry property.
4. Edit the transition for the added step and assign it to the Step1_transition object.
Depending on the number of steps intended for the sequence, continue to assign suitable
action and transition objects for each step. An example of a completed four-step sequence
SFC is shown in Figure 4.9.5-2.
