Sequence branch and loop structures

Equipment Sequence branches allow you to define steps in parallel paths that run simultaneously, or the conditional execution of a specific path among multiple alternate paths. Branches define the path for a subdivision of step elements within the diagram. You can create selective branches and simultaneous branches. Additionally, you can add loops to the diagram. A loop is a branching structure containing a selective convergence followed by a selective divergence.

Divergence and convergence

When creating an alternate (selective) or parallel (simultaneous) path for the execution of steps in an

diagram by adding a simultaneous or selective branch, it creates a divergence. Merge branch paths back into one path using a convergence branch.
