Digital System Interaction Test : (Quality Assurance of System Functions through Standardized Tests)

Technical building systems are becoming increasingly complex, more diverse and more strongly networked through building automation systems. As a result, resource-saving and energy-efficient operation can be achieved. In practice, however, faults and deficiencies often exist in the systems that prevent the most efficient plant operation possible. The deficiencies include, for example, an incorrect parameterization of systems, controller settings that are not matched and optimized to the system, and inadequate cross-plant automation functions. In practice, various methods are used to identify these deficiencies and ensure the quality of automation functions. These include visual inspection of the plant to be tested by certified testing experts. In addition, applications of monitoring and commissioning as well as user-oriented test sequences can be used for fault detection and quality assurance of automation functions. However, the aforementioned procedures are associated with time and configuration effort, which result in costs for their usage and configuration. In addition, they are not based on any generally valid and standardized procedure. Based on these findings, this paper describes the conceptual development of digital system interaction tests that can be used to check different cross-plant automation functions. On the one hand, the focus of the process is on implementing the test procedure as automatically as possible. On the other hand, it should be standardized and generally applicable. Due to the low configuration effort, time and costs for the use of the procedure can be reduced. The standardization of the test procedure enables the application to be used in different technical building systems and creates a transparent form of testing.
