Is there a need to create a flowchart in advance when creating a PLC ladder circuit?
If the ladder circuit is flowed, it cannot be expressed well.

① Is the flowchart suitable as a material to be created in advance when creating a ladder circuit?
② If it is different, what kind of material is best to make?
③ Also, what should I pay attention to when expressing in a flowchart?

I'm sorry for the abstract question, but please give me some advice.

    Is there a need to create a flowchart in advance when creating a PLC ladder circuit?

    I think there is nothing. There is a "ladder diagram" to show the processing flow of the PLC.

    Although there may be cases where a flowchart is written to show a general person (customer) who is not an engineer, a general flowchart probably shows a part that works in parallel. There will be insufficient functionality. You might be able to show something similar for UML activity diagrams.

    ① Is the flowchart suitable as a material to be created in advance when creating a ladder circuit?

    Not suitable. Each stage of the ladder operates inparallel, so the idea is fundamentally different from the one-way flowchart.
