註釋
The collected information related to the activities along the life cycle of an automation solution serves as basis for the comparative evaluation between a classically developed system and a mechatronicly developed decentralized system. The following results have been worked out with the characteristics from decentralized automation use cases as introduced in Section 3 in combination with the described mechatronic engineering approaches. The general advantages of engineering with mechatronic modules, such as, for instance, cross-discipline- work and the improved reuse or standardization of partial solutions, were already discussed in other papers and shall not be described here any further (Thramboulidis 2008, Löwen & Wagner 2009, VDI 2206). Application Effort and Complexity: The applicability and manageability of a modular, decentralized automation approach particularly regarding the modularization of automation and control functionalities must still be ensured. For this purpose, one must differentiate between the creation of the mechatronically modules in a predevelopment project and their application in the particular engineering projects. Overall, it can be expected that the specification and implementation effort to be performed in advance and the complexity for the creation of mechatronic modules with integrated automation and control functions, which are autonomous and can be integrated independently of each other, will increase substantially. For this purpose, bases for modules have to be created that are usable for different projects and configurable for the specific applications. This requires detailed knowledge of the domain, extensive technological expertise, and an understanding of the core functionality of the modules. One example for a starting point for this approach is the INTEGRA standard specifying first consistent mechatronic viewpoints for automotive production lines. These pre-produced modules facilitate the engineering for project-specific applications. The more plug & play modules are available the less effort is required for the engineering. In addition, project risks can be reduced by early validation of fulfillment of customer requirements due to availability of module descriptions and models. This, however, only applies if module adaptations occur which can be done by configuration, selection of variants, or extensions, and in which do not require any changes to the predefined core.
