5.114.3 Action types available for creating the positioning program
The program flow of the multi-purpose positioning is selected according to a sequence table which
can contain up to 100 references to "actions".
• 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.
• Each action type provides a certain number of actions which can be parameterised individually.
• One action can be called from several positions in the sequence table.
• After an action has been processed, the action in the next step of the sequence table is auto-
matically 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.
• The sequence table and the actions are displayed by parameters (codes with subcodes).
• Action calls are entered into the sequence table using a decimal number which contains the ac-
tion type  and the action number .
