Device descriptions play an important role in the design and commissioning of modern automation systems and help reducing the design time and costs. However, all established device descriptions are specialized for certain purposes and suffer from several weaknesses. This hinders a further design automation, which is strongly needed for the more and more complex automation systems. To overcome these...
The design of room automation systems is a challenging task with growing complexity and a high optimization potential. On the market, a high number of prefabricated devices from different manufacturers is available for a large variety of functions. This leads to a high number of device combinations and many design variants respectively, that should optimally realize the requirements. To overcome this...
The increasing complexity of modern building automation systems (BAS) results in higher initial investment costs for BAS compared to the costs for conventional building installation. This fact scares many potential customers off the application of BAS, although these systems offer significant energy cost saving potential. To reduce investment costs for BAS, automated design processes offer significant...
Embedded systems are used in many domains today. However, the design process of these systems is complex and time-consuming. In automation domains the complexity can be decreased by using function block based designs to specify the functionality of the system to be created. But this has to be done still manually. This paper introduces an approach to generate such function block based designs automatically...
The planning and design of building automation systems is a time consuming, error prone and nowadays more and more expensive task, consisting of a lot of repeated manual design steps done by specialized engineers. To reduce the engineering costs for such systems, the authors present a new automated top-down design approach within this paper. A knowledge-based system supports the planner at the requirement...
Established device descriptions for automation devices lack a machine understandable semantics, thus inhibiting desired tasks like a semantic retrieval of devices, their automatic parameterization and interoperability analysis or the automated design of automation systems. To overcome these limitations, an approach for a semantic specification of automation devices is presented, which covers the hardware...
The future design of large and complex building automation systems (BAS) needs to be increasingly efficient. The usage of prefabricated devices and design patterns alone is insufficient to face complex demands. New automated design approaches not only need to take over recurrent tasks, they also have to integrate more direct and smoother methods into the overall design process. This paper addresses...
Nowadays process data acquisition in automated installations is essential for efficient fault diagnosis during development and commissioning, but also for quality assurance, optimization and documentation. Classical solutions for monitoring of real-time PLC (programmable logic controller) devices lack flexibility and sampling resolution. Therefore this paper presents an approach, where an additional...
