    Supervisory Control and Data Acquisition (SCADA) systems are applications that collect information about equipment located in industrial plants and distributed over wide areas. Where control and supervision tasks require sophisticated automation schemes that provide access to production data and variables distributed in the field remotely, at various levels of plant automation [4], the complexity of these systems complicates their implementations. To carry out the implementation of SCADA systems it is necessary to have knowledge of specific programming languages of a modeling and simulation software (e.g., MATLAB) or knowledge of protocols for connection with industrial devices (e.g., MODBUS), so a person without such knowledge will not be able to build a fully functional system [1]. In addition, the development of SCADA systems takes a long implementation time, which increases the cost of building the system [1]. Therefore, the Model Driven Development (MDA) approach is widely used by Software Engineering, this approach is based on models and applies transformations during the development process, so that systems can be developed in an automated way and reusing software components. The MDA approach proposes several models to represent the system, each model describes the system from a high level of abstraction [2]. To build model-based SCADA systems, the construction of a software infrastructure has been carried out, with a Model Driven Development approach for the automatic generation of the source code that implements the design of SCADA Systems. The infrastructure provides: i) A graphical editor that facilitates the creation of models that describe the design of a SCADA system, ii) A transformation engine that takes as input SCADA system design models and generates the code that implements the SCADA system according to the programming language of a modeling software that allows programming the SCADA functionality (e.g., MATLAB) [3]. MATLAB is a proprietary software from MathWorks, and it is a control system used by engineers in all stages of development, from plant modeling to design, adjustment of control algorithms and supervisory logic [3], the effectiveness of this technological infrastructure has been tested in the micro-grid laboratory of the University of Cuenca, to design and implement SCADA systems
