Abstract:
Proposed in the paper is an approach to generate the PLC code from the Discrete Event System Specification (DEVS) model. DEVS have been widely accepted to model the real system for the discrete event system simulation. The objective of this paper is to generate PLC control code from the DEVS model. To achieve it, this paper proposes two steps. First step is to convert the real system into the virtual model using the ‘three-phase-modeling procedure’. In the second step, the obtained model is formalized with DEVS formalism. The final model consists of different components, among them the State manager and the Flow controller model plays vital role to generate PLC code. In this paper, proposed steps are described with a work cell example.
