Introduction
The alternative branch offers the possibility to program branches conditionally in the control flow of the SFC structure.
With alternative branches, as many transitions follow a step under the horizontal line as there are different processes.
All alternative branches are run together into a single branch again with alternative joints or Jumps where they are processed further.
