“…Vadi and Bayndir [76] describe an OPC-PLC-based RL for a synchronous motor control experiment. The most recent work found was reported by Prada et al, 2015 [14], where the OPC protocol and LabVIEW are used in a RL to manage a flexible manufacturing cell.…”

“…In Spanish universities, several RLs have been developed for control and automation pilot plants with research and educational purposes: University of León [13,14], University of Huelva [15,16], National Distant Education University (UNED) [17,18], Polytechnic University of Madrid (UPM) [19], University of Alicante [20], Polytechnic University of Catalonia (UPC) [21,22], University of the Basque Country (UPV/EHU) [23], University of Deusto [24,25], University of Jaén [26], and University of Almería [27]. Even an online platform, UNILabs [28], has been created to establish a network of virtual and remote laboratories integrated by several of these Spanish universities.…”

In this paper the design and implementation of a network for integrating Programmable Logic Controllers (PLC), the Object-Linking and Embedding for Process Control protocol (OPC) and the open-source Easy Java Simulations (EJS) package is presented. A LabVIEW interface and the Java-Internet-LabVIEW (JIL) server complete the scheme for data exchange. This configuration allows the user to remotely interact with the PLC. Such integration can be considered a novelty in scientific literature for remote control and sensor data acquisition of industrial plants. An experimental application devoted to remote laboratories is developed to demonstrate the feasibility and benefits of the proposed approach. The experiment to be conducted is the parameterization and supervision of a fuzzy controller of a DC servomotor. The graphical user interface has been developed with EJS and the fuzzy control is carried out by our own PLC. In fact, the distinctive features of the proposed novel network application are the integration of the OPC protocol to share information with the PLC and the application under control. The user can perform the tuning of the controller parameters online and observe in real time the effect on the servomotor behavior. The target group is engineering remote users, specifically in control- and automation-related tasks. The proposed architecture system is described and experimental results are presented.

“…Moreover, in many cases, only commercial software tools are available, which means an expense that is unaffordable in several applications. In the literature we can find many examples of access to remote systems where implementation is performed using commercial software, ad hoc designs or a mixture of both solutions [23,24,25,26,27,28,29,30,31,32,33]. In this regard, in the path towards the future generation of technological processes, there is a trend to replace proprietary approaches with open and standardized solutions [34].…”

Easy Handling of Sensors and Actuators over TCP/IP Networks by Open Source Hardware/Software

There are several specific solutions for accessing sensors and actuators present in any process or system through a TCP/IP network, either local or a wide area type like the Internet. The usage of sensors and actuators of different nature and diverse interfaces (SPI, I2C, analogue, etc.) makes access to them from a network in a homogeneous and secure way more complex. A framework, including both software and hardware resources, is necessary to simplify and unify networked access to these devices. In this paper, a set of open-source software tools, specifically designed to cover the different issues concerning the access to sensors and actuators, and two proposed low-cost hardware architectures to operate with the abovementioned software tools are presented. They allow integrated and easy access to local or remote sensors and actuators. The software tools, integrated in the free authoring tool Easy Java and Javascript Simulations (EJS) solve the interaction issues between the subsystem that integrates sensors and actuators into the network, called convergence subsystem in this paper, and the Human Machine Interface (HMI)—this one designed using the intuitive graphical system of EJS—located on the user’s computer. The proposed hardware architectures and software tools are described and experimental implementations with the proposed tools are presented.

Design, Control and Applications of Mechatronic Systems in Engineering

View full text Add to dashboard Cite

Typical mechatronic systems are a combination of advanced technologies involving several disciplines. This multidisciplinary approach to the development of industrial applications provides great opportunities for the implementation of e-learning environments and collaborative schemes. Engineering education, in particular, benefits from many of these advances, among which, virtual instrumentation is a useful tool for the development of virtual environments, e-learning spaces and, particularly, remote laboratories. This chapter describes the implementation of web-based laboratories that allow the remote operation of experiments used as training exercises in undergraduate engineering courses. The remote laboratories were developed using LabVIEW ® software, and they enable remote control and monitoring of laboratory equipment, allowing engineering students to perform experiments in real time, at their own pace, from anywhere, and whenever is suitable for them. Besides the experimental training that the web-based laboratories provide to students, the system is also a powerful teaching tool since real-time demonstrations of the experiments can be performed, and they also can be simultaneously monitored by a group of students. This approach is highly beneficial for engineering schools in developing countries, as resources can be shared through the Internet. A description of the system and three proposed experiments is presented, together with the experimental results.
