摘要:
The invention relates to an engineering system and to a method for planning an automation system (AS). In order to facilitate the planning of the automation system (AS), in particular in the event of a change in the configuration of the automation system (AS), the invention proposes an engineering system having means for allocating a class attribute to process variables of an automation process which can be carried out using the automation system (AS), wherein said process variables can be assigned to a common class, and means for addressing the process variables using the class attribute within a mathematical relationship.
