Parallel Branches

Several SFC branches can be parallel. The mark of parallel branches on chart is double horizontal line. Each parallel branch begins and ends with a step, i.e. there is only one condition of input/output in parallel branch:

In theory, parallel branches are executed simultaneously. In reality, it means — in a complete cycle, from left to right. Transition condition completing parallel branch is checked only in the case when last steps of each parallel branch are active. In this example, Shaking is executed once, then Digestion and Mixing operate in parallel till condition Ready is fulfilled.
