With recent trends in manufacturing automation, such as Industry 4.0, control software in automated production systems becomes more and more complex and volatile, complicating and increasing importance of quality assurance. Test tables are a widely used and generally accepted means to intuitively specify test cases for automation software. However, each table only specifies a single software trace,...
Automated production systems (aPS) are complex systems with high reliability standards which can — besides through traditional testing — be ensured by verification using formal methods. In this paper we present a development process for aPS software supported by efficient formal techniques with easy-to-use specification formalisms to increase applicability in the aPS engineering domain. Our approach...
In spite of the rising complexity and functionality of Programmable Logic Controller (PLC) software, a high degree in quality and reliability has to be guaranteed for automated production systems. Applying structured testing, faults can be recognized and eliminated early during the engineering process. Therefore, in this paper an approach for automatic test suite generation implemented with Fault...
