Implementación de sistemas distribuidos de bajo costo bajo norma IEC-61499, en la estación de clasificación del MPS 500 de la Universidad Politécnica Salesiana.

Abstract

The purpose of this work is to implement low-cost distributed systems under IEC-61499, at the classification station of the Universidad Politécnica Salesiana. The development of new technologies, new performance requirements and limitations given by the software and hardware manufacturer for automation has made new standards developed. The IEC-61499 standard is one of the latest automation trends that standardizes a programming environment for distributed systems. It has a high level of versatility for system design, since it allows to combine software independent of the hardware used. To implement the process, the 4DIAC software is used and new function blocks are created for the control of sensors and actuators, later FORTE Runtime was then programmed and executed on a raspberry Pi card. It is evident from the results that the programming through function blocks creates flexible and reconfigurable systems. It is concluded that the standard allows to control the algorithm through events, since it has a connection between the execution of the event flow and data flow, in this way priorities can be given in the order of execution of the function blocks. In addition the implementation was possible to show the reduction of costs by 78% compared to the system implemented with PLC. It is recommended in future research to perform a coupling circuit in the card to couple the signal of sensors and actuators.
