Introduction

Sections and LL984 segments (and also LL984 networks inside segments) are executed in the sequence in which they are displayed in the Structural View of the Project Browser.

To change this sequence, you can drag-and-drop sections, LL984 segments or LL984 networks inside the Structural View .

Restrictions

For dragging-and-dropping LL984 segments and networks the following rules apply:

• Sections (ST, LD, …) can not be dropped into LL984 segments.

• LL984 segments can not be dropped into other LL984 segments.

• LL984 networks can only be dropped into LL984 segments.

  LL984 networks can be dropped into the LL984 subroutine segment under the SR Sections) node of the MAST task.

  After dropping the networks, they are re-analyzed latest during next Build, because e.g. L9_LAB function blocks are only allowed in networks of the LL984 segment in the SR Sections node.

• When an LL984 network has an activation condition and is dragged-and-dropped into the LL984 subroutine segment, the LL984 network loses its activation condition because subroutine networks do not have activation conditions.

Drag-and Drop Between Applications

You can not drag-and drop LL984 segments and networks from one Control Expert application to another.

To copy sections between applications you have to use the import/export feature of Control Expert.
