“…It is worth mentioning that the CPTest+ language can be expanded to support some features specific to a particular test type, such as communication performance tests [19] or POU-oriented performance tests [1]. What is more, CPTest+ can be used to develop not only unit tests, but also integration and system ones, as shown in the following part of this paper.…”

“…Due to its specific requirements, it is important to prepare such a kind of software in a way that ensures its high quality and operation in erroneous scenarios, as well as decreases a number of problems that may be found while running on the plant. As stated in [1], there are some possibilities that could be useful for improving quality of control software, such as its modeling, standardized implementation, and detailed testing.…”

“…One of them is shown in [7] and describes a dedicated test definition language, named CPTest+. It has been also extended for testing performance of particular POUs [1] and communication between devices in DCSs [8]. Other interesting approaches to control software testing include the test-driven automation concept [9], industrial automation software development process based on tests [10], agile keyword-driven testing method [11], and deterministic replay debugging [12].…”

Original scientific paperThe control software is frequently used in various systems that perform important and responsible tasks in industry. During its development, it is crucial to ensure that the solution is created in a way consistent with assumptions and meets all functional requirements. One of important steps consists of testing particular software units, separated from the rest of system, using the off-line simulator. However, test results can be different in case of a fully-connected system when external factors, such as communication issues, should be also taken into account. In this paper, the authors present a concept of specification and execution of system tests, using the dedicated test definition language, named CPTest+. It has been extended by the additional ASSERT_COM instruction, which performs an assertion that is able to detect problems related to external factors, including communication. To enable automatic and systematic testing, the dedicated metric has been proposed. It takes into account the current link status and archived results to calculate the probability that the test case has failed due to communication problems.Key words: Control Systems, Communication, IEC 61131-3, Requirements, Testing Utjecaj komunikacijskih prekida na zadovoljenje funkcionalnih zahtjeva IEC 61131-3 distribuiranih sustava upravljanja. Upravljački software ječesto korišten u sustavima koji obavljaju kritične zadatke u industriji. Tijekom njegovog razvoja, važno je osigurati zadovoljenje svih bitnih pretpostavki i funkcionalnih zahtjeva. Jedan od važnih koraka u razvoju navedenog softwarea je testiranje njegovih pojedinih cjelina korištenjem offline simulatora, neovisno o ostatku sustava. Meutim, rezultati testiranja mogu se bitnije razlikovati u slučaju potpuno povezanog sustava sa svim pripadajućim eksternim faktorima, kao što su komunikacijski problemi, koje je takoer potrebno uzeti u obzir. U ovom radu autori predstavljaju koncept definiranja i izvršenja testova sustava korištenjem jezika za namjensko definiranje testova, nazvanog CPTest+. On je proširen dodatnom ASSERT_COM naredbom koja obavlja provjeru s mogućnošću detekcije problema uzrokovanih vanjskim faktorima, npr. komunikacijom. Kako bi se omogućilo automatsko i sistematično testiranje predložen je namjenski mjerni sustav. On uzima u obzir trenutni status veze kao i arhivirane rezultate kako bi se odredila vjerojatnost neizvršenja testnog slučaja uslijed komunikacijskih problema.
