iMMAS an Industrial Meta-Model for Automation System Using OPC UA

Abstract

Industry 4.0 promotes the integration of IT software technology with the industrial devices of a factory for the supervision and control of Industrial Automation Systems (IAS). In this paper, a novel metamodel called iMMAS (Industrial Meta-Model for Automation System) is proposed to simplify the development and deployment of an IAS. The metamodel provides a language for modelling the industrial process of a factory through industrial devices (including PLC, Soft-PLC or RTU) using new abstractions to conceptualize the IAS. This work presents how the models are performed and executed on an OPC UA environment, and how they can be used to generate a program for a PLC. A case study is also shown to test the applicability of the proposal presented.

Development of Cyber-Physical Security Testbed Based on IEC 61850 Architecture

“…ICS are divided into two main parts: (i) programmable logic controllers (PLCs) and (ii) discrete control systems (DCS), which also use PLC or some other batch process control device. Moreover, the ICS systems are mostly handled by Supervisory Control and Data Acquisition systems (SCADA), which provide a graphical user interface for operators to observe the system easily, receive possible alarms indicating out-of-band operation or to enter system adjustments to manage the process under control [1], [2].…”
