Init Step

Overview

The SFC Editor > Init Step command is used in the SFC (sequential function chart )editor to transform the currently selected step to an initial step (init step).

Thus the frame of the step element will change to a double line. The step previously having been the initial step will automatically change to a normal step and get displayed now with a single-line frame.

This transformation can be useful if you want to reconstruct an existing chart.

When you create a new SFC POU, an initial step element will be inserted automatically, followed by a transition (TRUE) and a jump back to the initial step.

The property initial step can also be enabled and disabled in the property dialog box of the step element. However, no automatic change of the settings of the other steps will be completed.

Also consider the possibility to set back the SFC to the initial step by using variables SFCInit or SFCReset.
