ResumenExisten diferentes lenguajes de programación de Controladores Lógicos Programables (PLC), el más común de ellos es el lenguaje de programación gráfico para autómatas programables llamado LADDER. Sin embargo, el lenguaje LADDER no es amigable en programas que requieren de cálculos de ecuaciones matemáticas, por ejemplo, el cálculo del volumen de un tanque en un control de nivel. Lenguajes alternativos como el Lenguaje de Control Estructurado (SCL) son menos estudiados dada su complejidad y poca popularidad en la pequeña y mediana industria. En este artículo se compara los resultados del lenguaje de programación LADDER y el lenguaje SCL generado mediante la herramienta Simulink® PLC Coder de MATLAB® tomando como caso de estudio el cálculo de volumen de un tanque. Finalmente, este trabajo demuestra que la herramienta Simulink® PLC Coder presenta una alternativa de desarrollo más eficiente.

“…Some other approaches adopt the verification environment of a theorem prover: e.g., to check the correctness of SFC programs, automatically generated from a graphical front-end, in Coq [3]; and to formalize PLC programs using higher-order logic and to discharge safety properties in HOL [24]. These works are similar to ours in that PLC programs are formalized and supported for mechanized verifications of implementations.…”

Abstract. Many industrial control systems use programmable logic controllers (PLCs) since they provide a highly reliable, off-the-shelf hardware platform. On the programming side, function blocks (FBs) are reusable components provided by the PLC supplier that can be combined to implement the required system behaviour. A higher quality system may be realized if the FBs are pre-certified to be compliant with an international standard such as IEC 61131-3. We present an approach to formalizing FB requirements using tabular expressions, and to verifying the correctness of the FBs implementations in the PVS proof environment. We applied our approach to the example FBs of IEC 61131-3 and identified issues in the standard: ambiguous behavioural descriptions, missing assumptions, and erroneous implementations.

Abstract-Programmable logic controllers (PLCs) represent a typical class of embedded software systems. They are widely used in safety-critical industrial applications, such as railways, automotive applications, etc. The paper presents a novel method to specify and verify PLC software systems with the theorem proving system Coq. Dependent inductive data types are harnessed to represent the component specifications. Modular and parameterized specification and verification are proposed. An illustrative example demonstrates the effectiveness of the method.
