Abstract
The adaption of manufacturing companies to frequent market changes is essential for remaining competitive. In that way, Reconfigurable Manufacturing Systems are interesting as they offer the opportunity to choose the organization of their elements very late in the conception and to modify it dynamically or not during exploitation. This results extensions of control to control/command that includes monitoring, supervision and several control versions. As a consequence of the growing complexity, managing the overall design process, the costs and the delays have become very challenging. One challenge is to easily get several controls depending on exploitation modes, on the PLC targets and consistent with the HMI supervision in order to efficiently pilot the systems. The designer has also to ensure that the control does not contain errors. To address these issues, some automatic generation flows have been proposed. They are based on two main principles: A component based approach that enables reusing and model driven engineering principles that provide a systematic way to derive high level models to platform dependent models such as control codes and as a result, different tools implement the presented flows. The first one Comgem generates control codes for several executing platforms. The code enables different levels of reconfigurations. The second one Anaxagore both generates control and HMI supervision interface that guarantees consistency. Each tool takes part of our demo platform named SCAP Industry of the Future. The provided solutions enable to better take the system expertise into account. The designers do no more focus on low level code constraints and can bring their skill at the level of the system. As computing and data is more and more present in manufacturing systems, future developments have to be carried on verification of the solutions that should incorporate some cyber security features.
