How to initialize an SFC sequence back to the Init step in EcoStruxure Control Expert?
Issue
Need to reset an SFC (Sequential Function Chart) sequence to its initial step during runtime in EcoStruxure Control Expert.
Product Line
EcoStruxure Control Expert software, applicable to Modicon M340, M580, and other supported PLC platforms.
Resolution
By implementing the block INITCHART in the application, it resets and allows the normal start of the selected Sequential Function Chart.
With a rising edge signal at the input INIT_I of the block, the selected sequence is stopped and all steps are reset. As long as the signal remains TRUE, the sequence remains stopped and cannot be started.
With a falling edge at the input INIT_I of the block, the sequence is started normally and the initial step is activated. This is shown for one cycle with a TRUE (1) signal at the output INIT_O.
