A New Method for Verification and Evaluation of PLC Software

OpenAlex İngilizce

Varying market demands and changes in production standards require production systems to be effortlessly modifiable and quickly operational. On the other hand, designing, developing, and testing the control system of a new production system prove costly and time-consuming. Therefore most engineers write codes intuitively and apply basic and insufficient tests. This study aims to develop a reusable and quickly implementable method that will accurately translate RTC program and the behavior of RTC in a modular Petri net model. Through this translated model the system and safety requirements written in the Computation Tree Logic can be verified. An advantage of this method is that it does not require a plant model which makes it reusable for new plants and provides a quick verification method for codes written intuitively. A case study is given to demonstrate the correctness of our method.
