[5-2] Sequence table (schematic diagram)
What is an action?
 An action comprises a clear functionality which is described with a few parameters.
 Different action types are available which serve to implement, for instance, program
branching, switching operations, waiting times and counters.
 Before every action type a defined number of actions is available which can be
individually parameterised. The parameters of the actions of the same type only differ
in the subcode.
 An action can be used in several steps if always exactly the same task is to be carried
out.
 After an action has been processed, the action in the next step of the sequence table is
automatically processed unless it is jumped to another step in the sequence table due
to a branch.
 One action can be maximally processed per computing cycle.
