12.27.1 SFC Editor commands
The commands of category 'SFC' are provided by the 'SFC Editor' plug-in and are
available for programming in the SFC editor.
By default they are to be found in the "SFC" menu. If necessary, open the Customize
dialog, category 'Menu', to view or modify the current menu configuration.
The commands:
• Init step
• Insert step-transition
• Insert step-transition after
• Parallel
• Alternative
• Insert branch
• Insert branch right
• Insert action association
• Insert action association after
• Insert jump
• Insert jump after
• Insert macro
• Insert macro after
• Zoom into macro
• Zoom out of macro
12.27.2 Init step
This command (category 'SFC') is used in the SFC editor to transform the currently
selected step to an init step.
Thus the frame of the step element will change to a double-line. The step previously
having been the init step will automatically change to a normal step and get displayed
now with a single line frame. This transformation might be useful if you want to
reconstruct an existing chart.
When creating a new SFC POU automatically an init step element will be inserted
followed by a transition (TRUE) and a jump back to the init step.
Notice the possibility to set back the SFC to the init step by using variables SFCInit resp.
SFCReset.
