“…Los bloques de función son definidos por el estándar internacional IEC 61499 [3,4], el cual ha sido desarrollado conjuntamente con el estándar IEC 61131-3 que define aspectos de los FB [5]. Existen aplicaciones comunes usando FB, como el diseño de sistemas distribuidos, control de nivel en tanques de un proceso, sistemas de control industrial basado en FB [6], diseño de prototipos en diferentes niveles de control [7,8], y arquitecturas de desarrollo de soporte a ingeniería usando FB [9].…”

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.

“…Furthermore, there are approaches which combine STEP-NC with function blocks. One describes the converting of STEP-NC to function blocks [29] and others use STEP-NC as the communication format to send data between two connected function blocks [31,32].…”

In many industries the focus in CAx based manufacturing has changed from fixed process chains to ones which can adapt to dynamic inputs. This way process chains can take measurement data into account to produce optimal results. Unfortunately, existing approaches do not integrate well with the existing CAx systems since they do not ensure that existing processes will be kept unchanged. This restriction leads to a low adaption rate in some industries. Especially in the aerospace industry every change in the manufacturing processes will result in high costs. In this paper it is shown that an extended function block approach can be integrated with existing CAx systems while allowing the modeling and controlling of adaptive process chains with reduced data loss at the same time. In order to achieve this goal, data port manifests are introduced which announce supported data formats and features of the corresponding function block. This extension reduces information loss at system interfaces and helps to ensure that required data will be transferred between function blocks. A case study will show how this extension can be used in a common CAx system

“…Over the past decade, the effectiveness of the IEC 61499 standard in distributed control systems has been extensively studied in various applications, such as airport baggage handling systems [4], [5], manufacturing control [6] with closed-loop verification [7], [8], mechatronics [9], [10], building automation systems [11], machining [12], [13], process control [14], [15], and smart grids [16], [17]. These case studies have confirmed many advantages of IEC 61499 in terms of design and redesign efficiency and better interoperability and reusability [18].…”
