Design of Graphical User Interface (GUI) on IoT-based remote laboratory for Programmable Logic Controller (PLC) practicum and pneumatic simulation

Abstract

The remote laboratory system allows users to conduct lab work via a remote-controlled lab computer. Each computer has a different interface to interact with the operating system. This affects the comfort and effectiveness of users in accessing remote laboratories. Based on this, we need a support system in the remote laboratory to maximize user time in practicing. The interface on the computer lab becomes an important factor in supporting a practicum that uses computers. GUI (Graphical User Interface) is an interface that allows users to interact with the operating system graphically. Unlike the CLI (Command Line Interface), which uses the command line, the GUI uses a graphical menu, thus allowing users to more easily and efficiently interact with the operating system. The main features of the GUI are made up of three components. The components in question include time management features, application selection, and notifications. If already connected to the GUI, users can easily open the applications provided, such as CX-Programmer, Pneumatic Festo Fluidsim, and the camera. Also, the GUI functions as a timer and notifies users. This can be seen from the automatic connection and disconnection between the user and the computer lab if the practicum time is up.
