“…Simulink is most appropriate for the design and modeling of controllers and is an environment often used. We showed in [1,3] that the time behavior of the controller on PLC is equal to the time behavior of the corresponding Simulink model. In spite of this result external disturbing factors may occur during runtime, which may influence the time behavior in an unpredictable way.…”

“…In this case it is necessary to extend the controller in order to make it possible to be enabled. We simply take a controller imported from Simulink [1,3] and extend it with the condition enabled.…”

“…The correctness of the functionalities of the code generator was demonstrated with the help of a real Simulink model from a wind turbine and a paper machine [3]. It was shown that the time behavior in Simulink corresponds 99.9% (coefficient of determination) to the time behavior of the generated code.…”

“…A manual transformation of the controller model to Programmable Logic Controller (PLC) is not necessary any more. Developed by the authors [1], [3] a code generator allows an automatic model transformation from a discrete control loop in Simulink into Continuous Function Chart (CFC) taking PLC properties into consideration. CFC is not part of IEC 61131-3 but it is supported by many tools such CoDeSys or STEP7.…”

Integration of control loops in an UML based engineering environment for PLC

This paper presents a UML-based engineering environment for the design and implementation of hybrid systems in forming technology. The discrete superordinate steps of forming technology are programmed as an activity diagram (UML). Some process steps include control loops which are modeled in Simulink. The control loops are automatically generated into Continuous Function Chart (CFC) in Programmable Logic Controller (PLC). The paper describes how the controllers can be distributed with different task cycle times and how the performance of these controllers can be ensured during runtime. In the process, the activity diagram is compared with the standard IEC 61499 considering the aspects usability and execution/implementation.
