Due to an increased product variety, the need for flexibly configured assembly systems is steadily growing. In contrast to classic assembly lines with predominantly rigid conveyor technology, efficient, individual assembly routes with cycle-independent processing times are implemented in a dynamically interconnected assembly system using intelligent control and AGVs. This article presents the most important factors for the IT-related implementation of a dynamically interconnected assembly system and shows which existing standards from the field of Industry 4.0 can be used for this purpose.
