The FBD/LD/IL > Toggle Parallel Mode command is available if the LD editor is active, and a vertical line of a parallel branch is selected. It toggles the parallel branch between an OR construct and the Short Circuit Evaluation (SCE).
You can program closed parallel branches in an LD network as short circuit evaluation (SCE) or OR constructs. SCE branches are displayed with double vertical lines, OR branches are displayed with single vertical lines. Also refer to the description of the Parallel Branch.
