As part of the on-line modifications associated with a prepositioning of the SFC, Control Expert behaves in a specific way when:

  • Sections are animated.

  • A prepositioning is performed for this section and for the sections of the macro-steps.

Step

Action

1

Perform a modification in one of the sections.

Result:

  • The animation of the section is stopped.

  • The prepositionings of the SFC and its macro-sections are reset to zero.

2

Use the command Build > Build Changes to generate the modifications.

3

Use the command PLC > Transfer project to PLC to load the modifications in the PLC.

Result:

  • The animation of the modified section is relaunched and displays the current state (the prepositioning is reset to zero).
