Transitions Folder and Transition Programs
Transition programs are registered in the Transitions folder under the SFC program.
A transition program describes the step progression conditions, which need to be
expressed by multiple input signals or by the more complex ladder or ST logic.
Transition programs are associated with an SFC chart’s transition by selecting the
same transition name.
Subcharts Folder and Subchart Programs
Subchart programs are registered in the Subcharts folder under the SFC program.
A subchart program allows an SFC program with large-scale step progression control
to be developed in parts, improving the reusability and visibility of the program and
allowing for more structured programming of the SFC program.
Subchart programs are subcharts for SFC charts and are associated with an SFC chart
by selecting the same subchart name. In program view, it is possible to check whether
an SFC subchart is a partial SFC chart of the SFC program.
SFC Editor
Displays an SFC chart or subchart.
By providing a split SFC view and program view display, the SFC chart can be viewed
simultaneously with the associated action program or transition program.
