SFC Elements

When working in Sequential Function Chart (SFC) programs, insert these elements. A program always has an initial step.
  • Steps
  • Transitions
  • Sequence Controls
  • Jumps to Steps
When inserting steps and transitions, these are assigned a default naming convention including numbering. For steps, the default naming is Sn where S indicates a step and n indicates the numbering for the step. For transitions, the default naming is Tn where T indicates a transition and n indicates the numbering for the transition. Rename steps and transitions. However, when renaming steps and transitions using the default naming convention and changing only the numbering, renumber these elements to a numbering scheme starting from top to bottom, then from left to right.

To renumber steps and transitions
Renumbering ignores steps and transitions using a naming convention other than the default Sn for steps and Tn for transitions.
  1. Open the SFC program for which to renumber the steps and transitions.
  2. From the
    Tools
     menu, point to
    Multi-language Editor
    , and then click
    Renumber Steps and Transitions
