22 Sequential Function Chart Quiz

In the context of the diagram, what does SFC stand for?

• Sequential Function Chart

• State Flow Chart

• System Flow Chart

• Signal Flow Chart

How does sequential logic differ from ladder logic?

• Each step is executed simultaneously

• Each step is executed in isolation and progresses only upon completion

• Each step is executed randomly

• Each step is executed based on user input

What type of logic is used when each step is tested in each scan?

• Sequential logic

• Ladder logic

• Boolean logic

• Fuzzy logic

What is the main difference between SFC and ladder logic?

• SFC uses a flowchart-like structure, while ladder logic uses a relay logic diagram

• SFC is simpler than ladder logic

• Ladder logic is used for complex processes, while SFC is not

• SFC is only used in software, while ladder logic is used in hardware

When does a step become active in the SFC?

• When the succeeding transition is satisfied

• When the prior transition is satisfied

• When the action is performed

• When the branch is executed

When IN 1 is active, which states are realized simultaneously?

• State 0 and State 1

• State 1 and State 2

• State 2 and State 3

• State 1, State 2, and State 3

What does SFC do to complex processes?

• It combines them into one large process.

• It breaks them down into manageable steps.

• It ignores them.

• It simplifies them into a single step.
