2-6   SFC Elements

An SFC is a program that specifies the operation of a plant or machine in flowchart form. Since it allows the flow of processes 

to be programmed in a natural manner, it facilitates the programmer to develop programs efficiently and to grasp the flow of a 

program as the flow of processes.

For example, the process of painting automobiles can be depicted as shown below in an SFC form.

Start 

Hold body 

Move 

Stop at predefined position 

Paint 

End of painting 

Move and dry body 

Start 

STEP 1 

STEP 2 

STEP 3 

[Transition condition 1] 

[Process 1] 

[Transition condition 2] 

[Process 2] 

[Transition condition 3] 

[Process 3] 

(STEP1) 

(ACT01) 

When represented 

in SFC form 

(STEP2) 

(ACT02) 

(STEP3) 

(ACT03) 

(T1) 

(T2) 

(T2) 

N   ACT01 

N   ACT02 

N   ACT03 

T1 

T2 

T3 

The elements of an SFC have the following meanings:

Start 

STEP 1 

N   ACT01 

T1 

Transition 

(condition for moving 

to the next step) 

Initial step 

(beginning of processing) 

Actions 

(describes the process) 

Action qualifier 

(an alphabetic character indicating 

the control at which the action is to be taken) 

 

Step flag (connects the step to an action) 

Step 

(segmented elements of a process) 

Each action or transition must be assigned to a BOOL variable or programmed using the IL, ST, LD, or FB language.

Notes:

Up to 24 characters are allowed for SFC 

step, action, and transition names.
