“…3 ), (taking advantage of the characteristic of physical devices in which the server side is also integrated), in general, an application can play both roles. Within an OPC UA Server, the nodes (contained in the Address Space) [39] represent real objects and can be freely structured in networks, hierarchies, and archives. OPC UA Clients can access data either through a Req/Rsp mechanism or through Subscription (push mode), and thanks to OPC UA a client can access a small portion of data of a complex system, without knowing the complete information model [37] .…”

“…SECS/GEM stands for Semiconductor Equipment Communication Standard/Generic Model for Communications and Control of Manufacturing Equipment and is the umbrella term for the SEMI communication standards listed as follows. The SECS/GEM is a widely used protocol in the manufacturing sector and has been so for many years [38]. From Intel and Samsung to Broadcom and UMC, IBM and Qualcomm, SK Hynix and Micron, NXP and Toshiba, TXN and Toshiba, and so on, the SEMI SECS/GEM has been the lifeblood of the semiconductor industry for years [39].…”

Starting from the First Industrial Revolution to the current and Fourth Industrial Revolution (or Industry 4.0), various industrial machines are present in the market and manufacturing companies. As standardized protocols have become increasingly popular, more utilities are switching to Internet Protocol (IP)-based systems for wide-area communication. SECS/GEM is one of the standards that permit industries to collect information directly from the machines, either using RS323 or TCP/IP communication. TCP/IP communication is becoming more critical than ever, especially given our accelerated digital transformation and increasing reliance on communication technologies. The growth of IT is accelerating with cyberthreats as well. In contrast, security features in the SECS/GEM protocol may be neglected by some companies as it is only used in factories and not mostly used in the outside world. However, communication of SECS/GEM is highly susceptible to various cyberattacks. This paper analyzes the potential replay-attack cyberattacks that can occur on a SECS/GEM system. In replay attacks, this paper supposes an adversary that wants to damage an operation-based control system in an ongoing condition. The adversary has the ability to capture messages to watch and record their contents for a predetermined amount of time, record them, and then replay them while attacking in order to inject an exogenous control input undetected. The paper’s objectives are to prove that SECS/GEM communication is vulnerable to cyberattack and design a detection mechanism to protect SECS/GEM communications from replay attacks. The methodology implements a simulation of the replay-attack mechanism on SECS/GEM communication. The results indicate that the design mechanism detected replay attacks against SECS/GEM communications and successfully prevented them.

“…To overcome this limitation, OPC Data Access (DA) servers can be implemented for real-time data exchange between https://doi.org/10.31436/iiumej.v24i1.2366 PLC and MATLAB using the MATLAB OPC Toolbox [12]. OPC DA server provides specification for the transfer of real-time data from the data acquisition device [13,14].…”

The pH neutralization process is a highly non-linear process and time delay system that is difficult to control and to accurately model mathematically. Therefore, the empirical method, which needs reliable experimental data to represent the process dynamics, is often used. In this paper, the performance of the PLC-based PID controller was studied using a different adjustment of the acid dosing pump stroke rate in the pH neutralization process. The pH neutralization process is a single-input, single-output system where the manipulated variable is the alkali dosing pump stroke rate, the controlled variable is pH, and the acid dosing pump stroke rate is set as a constant. The acid dosing pump stroke rate was adjusted to 10%, 15% and 25%. The results showed that the best performance of the PID controller was based on setpoint tracking when the setting of the acid dosing pump stroke rate was set at 10%, which could be used as experimental data in the empirical method. In addition, the real-time control system was integrated between PLC and MATLAB using National Instruments OPC server to access the experimental data in real-time, conduct simulation, and to develop the advanced control in the future. ABSTRAK: Peneutralan pH adalah proses tidak linear yang sukar dikawal dan sukar mendapat model matematik yang tepat. Oleh itu, kaedah empirikal memerlukan data eksperimen masa nyata bagi mewakili proses dinamik untuk mengatasi masalah ini. Kajian ini adalah berkaitan kajian prestasi pengawal PLC-berdasarkan PID menggunakan pelbagai perubahan kadar strok pam dos asid dalam proses peneutralan pH. Proses peneutralan pH ini adalah sistem satu input/output, di mana pemboleh ubah yang dimanipulasi adalah kadar peratusan strok pam dos alkali menggunakan pam peristaltik, pemboleh ubah kawalan ialah pH dan pemboleh ubah malar ialah peratusan dos asid.Kadar strok pam dos asid dilaraskan pada 10%, 15% dan 25%. Dapatan kajian menunjukkan prestasi terbaik kawalan PID adalah berdasarkan pengesan titik-set apabila kadar strok pam dos asid dilaraskan pada 10%, di mana ianya berkesan apabila digunakan sebagai data eksperimen dalam kaedah empirikal. Tambahan, kajian ini telah berjaya membentuk sistem kawalan masa nyata bagi proses penutralan pH menggunakan PLC dan MATLAB melalui pelayan National Instruments OPC bagi membolehkan pertukaran data eksperimen secara masa nyata yang cekap, menjalankan simulasi dan pembangunan kawalan termaju pada masa hadapan.
