Sequence

The Sequence construct is used to define a strict order of branches’ execution. It can have up to n branches, each specified with the position in the execution’s order. In RST a sequence relation is defined, but it is used there to define the sequence of information, which may or may not be presented in the same order as defined.
Figure Sequence shows the state chart for the Sequence construct. It defines that the execution order of the nuclei is the same as modeled. The next nucleus is executed after the previous nucleus has been finished.
