“…However, the limitations of this system are that it can only be applied to SCADA that communicates with Modbus RTU traffic. In reference, 8 the authors designed a proportional-integral-derived (PID) controller for the rectifying of ethanol, enabling the production of highly concentrated products and temperature control. The analysis using different mathematical models is the best way to manage the temperature of the first plate of the correction column.…”

The paper introduces a Programmable Logic Controller (PLC) / Human Machine Interface (HMI) system incorporated along with machine learning (ML) classifiers. Although some other studies have incorporated ML techniques to predict and control petroleum product terminals in terms of concentration, the proposed framework incorporates Add On Instruction (AOI) programming, PLC, and ML methods to automatically monitor petroleum products terminals. The framework adds an AOI in programming to achieve maximum usage of processor capabilities. Moreover, it uses AOI for programming in cooperation with the ladder diagram (LD). This leads to simplifying the LD graphical programming language, reducing the time of scanning, and making facilitate troubleshooting. The AOI is merged with ML to automate tank level detection and maintain good operational conditions and consequently protect these expensive essential assets. The introduced framework consists of three stages. The first stage is the PLC programming phase where the PLC is created using Add-On instructions. Next, HMI graphic displays are drawn and linked to the PLC tags in the following stage. During the third stage, the actual process readings are applied to the system based on ML algorithms to test its functionality. The proposed system results indicates a reduction in the LD number, highest program size, and maximum time of scanning. The results indicate that the AOI can help to trace the program more easily in fault situations. Besides, additional program instructions could reduce processor memory, system construction costs, and upgrade projects.

“…PLC merupakan suatu piranti elektronik yang dirancang untuk dapat beroperasi secara digital dengan menggunakan memori sebagai media penyimpan instruksi-instruksi internal untuk menjalankan proses, fungsi pewaktu, fungsi aritmatika, dan fungsi lainnya dengan cara memprogramnya [4]. PLC banyak digunakan dalam berbagai sistem pengendalian seperti conveyor dan motor induksi [ Beberapa penelitian penggunaan PLC pada sistem biodiesel fokus pada otomasi reaktor transesterifikasi biodiesel [3], pembuatan sistem pembilas/ pencuci otomatis [8], proses rektifikasi/ perbaikan etanol secara otomatis [9], dan lain sebagainya. Fokus penelitian ini adalah pemodelan sistem biodiesel berbasis PLC menggunakan bahasa ladder.…”

Biodiesel is one type of biomass as a renewable energy resource. Biodiesel system is a sequential system that can be controlled with a programmable logic controller (PLC) device. Sequential system problems can be solved by making a state diagram that represents the conditions and transitions of the system. Biodiesel system is represented in a state diagram then converted into a ladder diagram as one of the programming languages of a PLC. The method of converting state diagrams into ladder diagrams is structured programming method used by both levels, beginners and experts in running PLCs. The advantage of this method is reliability in detecting errors in the process. The error can be known clearly and structured by programmers. The design of the human-machine interface (HMI) of the biodiesel system in this study was made on CX One software (CXP and CXD) using a PLC type CP1E. System design made based on a state diagram has been successfully tested. In this design, the required memory is 6.5% of the total memory of the PLC CP1E.

“…The programming language that has gained the greatest popularity among PLC programmers is the Ladder Diagram language [9]. The reason for this is that it is easy to understand due to its similarity to contact-relay diagrams [10]. Ladder logic also allows the user to perform more complex operations such as arithmetic and time operations.…”

This paper presents the synthesis of a pneumatic control system for a selected configuration of the transport path for the delivery of rolling elements to spiral storage in inter-operational transport. The sequential control system sets the state of the manifolds to ensure a flow of workpieces to serve the subsequent storage. The essential module of the control system is the memory block. It is developed based on a storage filling sequence graph. The filling level of the storages can be monitored in one or two points using sensors. The rolling element displacement control sensors work together with appropriately designed systems to execute the delay of the rising and falling edge input signal. By using a two-level control of the filling level of the storages, it is possible to control the emptying status of the storages as a function of the technological time of removal of the items from the storage between the two control points. Control systems were synthesised and verified using Festo’s FluidSim computer programme.
