Abstract:
We address the formal verification of the control software of critical systems, i.e., ensuring the absence of design errors in a system with respect to requirements. Control systems are usually based on industrial controllers, also known as Programmable Logic Controllers (PLCs). A specific feature of a PLC is a scan cycle: 1) the inputs are read, 2) the PLC states change, and 3) the outputs are written. Therefore, in order to formally verify PLC, e.g., by model checking, it is necessary to describe the transition system taking into account this specificity and reason both in terms of state transitions within a cycle and in terms of larger state transitions according to the scan-cyclic semantics. We propose a formal PLC model as a hyperprocess transition system and temporal cycle-LTL logic based on LTL logic for formulating PLC property. A feature of the cycle-LTL logic is the possibility of viewing the scan cycle in two ways: as the effect of the environment (in particular, the control object) on the control system and as the effect of the control system on the environment. For both cases we introduce modified LTL temporal operators. We also define special modified LTL temporal operators to specify inside properties of scan cycles. We describe the translation of formulas of cycle-LTL into formulas of LTL, and prove its correctness. This implies the possibility ofmodel checking requirements expressed in logic cycle-LTL, by using well-known model checking tools with LTL as specification logic, e.g., Spin. We give the illustrative examples of requirements expressed in the cycle-LTL logic.

Abstract:
Given the growing computational power of embedded controllers, the use of model predictive control (MPC) strategies on this type of devices becomes more and more attractive. This paper investigates the use of online MPC, in which at each step, an optimization problem is solved, on both a programmable automation controller (PAC) and a programmable logic controller (PLC). Three different optimization routines to solve the quadratic program were investigated with respect to their applicability on these devices. To this end, an air heating setup was built and selected as a small-scale multi-input single-output system. It turns out that the code generator (CVXGEN) is not suited for the PLC as the required programming language is not available and the programming concept with preallocated memory consumes too much memory. The Hildreth and qpOASES algorithms successfully controlled the setup running on the PLC hardware. Both algorithms perform similarly, although it takes more time to calculate a solution for qpOASES. However, if the problem size increases, it is expected that the high number of required iterations when the constraints are hit will cause the Hildreth algorithm to exceed the necessary time to present a solution. For this small heating problem under test, the Hildreth algorithm is selected as most useful on a PLC.

Abstract:
More and more control systems are based on industry microprocessors like PLC controllers (Programmable Logic Controller). The most commonly used control algorithm is PID (Proportional-Integral-Derivative) algorithm. Autotuning procedure is not available in every PLC. These controllers are typically used in cooperation with HMI (Human Machine Interface) devices. In the study two procedures of autotuning of the PID controller were implemented in the HMI device: step method and relay method. Six tuning rules for step methods and one for relay method were chosen. The autotuning procedures on simulated controlled object and PLC controller without build-in autotuning were tested. The object of control was first order system plus time delay.

Abstract:
Industrial discrete event dynamic systems (DEDSs) are commonly modeled by means of Petri nets (PNs). PNs have the capability to model behaviors such as concurrency, synchronization, and resource sharing, compared to a step transition function chart or GRAphe Fonctionnel de Commande Etape Transition (GRAFCET) which is a particular case of a PN. However, there is not an effective systematic way to implement a PN in a programmable logic controller (PLC), and so the implementation of such a controller outside a PLC in some external software that will communicate with the PLC is very common. There have been some attempts to implement PNs within a PLC, but they are dependent on how the logic of places and transitions is programmed for each application. This work proposes a novel application-independent and platform-independent PN implementation methodology. This methodology is a systematic way to implement a PN controller within industrial PLCs. A great portion of the code will be validated automatically prior to PLC implementation. Net structure and marking evolution will be checked on the basis of PN model structural analysis, and only net interpretation will be manually coded and error-prone. Thus, this methodology represents a systematic and semi-compiled PN implementation method. A use case supported by a digital twin (DT) is shown where the automated solution required by a manufacturing system is carried out and executed in two different devices for portability testing, and the scan cycle periods are compared for both approaches.

Abstract:
A cable car is a hanging car that runs by cable. Cable car carrier controlled by DC motor. The cable car can be a solution to accommodate the mobilization of agricultural commodities in areas that are difficult to access while still paying attention to safety and reliability. In this research, the speed of a cable car would be automatically controlled with Programmable Logic Control (PLC). PLC functions as a cable car operation controller by considering 3 parameters, namely: wind speed, maximum load weight, and distance (meters). The speed of the cable car is controlled by the PLC using fuzzy logic. Cable car speed is based on parameters of wind speed, load weight and distance. From the results obtained, the PLC has worked well in regulating the speed of the cable car and if any parameter exceeds the PLC limit, it can turn off the cable car.

Abstract:
Programmable Logic Controller (PLC) merupakan suatu piranti yang dibuat sebagai pengganti kumpulan relai-relai mekanik yang digunakan dalam sistem kontrol. PLC berkerja dengan cara membaca instruksi-instruksi dari masukannya. Karena PLC pada umumnya memiliki harga yang cukup mahal dan hanya beberapa orang yang dapat mempelajarinya, maka dibuatlah PLC trainer. PLC trainer dirancang menggunakan mikrokontroler Arduino Uno, modul input (berupa: toggle switch, push button, dan limit switch), dan modul output (berupa: LED, seven segment, motor DC, dan buzzer). PLC trainer juga dilengkapi prototype lampu lalu lintas sebagai modul output simulasi lampu lalu lintas empat arah. PLC trainer memanfaatkan LDmicro untuk membuat pemrograman ladder diagram dengan instruksi-instruksi sesuai dengan keinginan programmer dan menggunakan software Xloader untuk upload program ke Arduino Uno. Dari hasil pengujian diperoleh bahwa mikrokontroler Arduino Uno dapat dimanfaatkan sebagai PLC trainer untuk modul pembelajaran.Kata kunci: Programmable Logic Controller, Arduino Uno, modul input-output, lampu lalu lintas

Abstract:
The PLC-based tension training system consists of three-phase asynchronous motors, programmable logic controllers (PLC), inverters, touch screen and sensor. Taking PLC as the controller, the system uses two sets of three-phase asynchronous motors to complete the delivery and winding of fibers, uses two inverters respectively to control the operation of the motors, and measures the fiber tension through tension sensor, and then feeds back the result to the PLC. Besides, by the touch screen control interface design, the system can achieve single motors inching, winding, and unwinding, two motors simultaneous operation and other operation modes. PID, fuzzy PID, genetic algorithm based PID and other algorithms can be used in the tests of the system. The PLC-based tension training system is of great help for enhancing the hands-on ability of college students or junior technical staff.

Moveable gates for the real-time control (RTC) of sewer systems storage capacities are usually operated by controllers which, on the basis of local water level or flow velocity measurements, calculate the regulation errors of the monitored variables, determining the necessary regulator movements to lead the flow conditions to the desired set point. In this paper the results of an investigation on the influence of proportional-integral-derivative (PID) controllers and programmable logic controllers (PLC) for the RTC of moveable sluice gates positioned into sewer systems are presented. The analysis of response time, damping and regulation errors provided information on the PID parameter calibration values and on the PLC control function performances. A comparison between the two kind of controllers has also been carried out.

Abstract:
Abstract The paper describes a prototype operator panel, which was designed to operate with the S7-200 family of Programmable Logic Controllers (PLC-s) from Siemens. Most of the functionality of the operator panel was implemented in a computer program, which runs on a PC-class computer. The program communicates with a PLC through its communication port configured in the Freeport mode. Two kinds of interface between the PC, and the PLC are supported: wired, and wireless. For wired connection a standard PC/PPI cable supplied by Siemens is used. For wireless connection two communication modules were designed, which operate in the free 433 MHz band. The operator panel program is intuitive, and easy to use. States of PLC inputs and outputs are presented using graphical objects. It is possible to modify states of the outputs, and monitor and edit any variable in the M and V memory in the PLC. The application supports also alarming. The program can be run on any computer with the MS Windows operating system installed. This makes the solution very cost-effective. Providing both wired and wireless communication radically increases flexibility of the proposed solution. The panel can be quickly mounted in areas, where pulling new cables is inconvenient, difficult or expensive.

Based on the fact that a large number of timing controllers are needed in the applications like sequential logic control and programmable controller, this paper proposed a PLC timer system based on ARM+FPGA, in which ARM is used to execute user program while FPGA is used for timer operation in parallel. The FPGA timer module consists of timer controller, timer dynamic parameters and soft contact state register, the timer controller carries out counter operation for timing unit every 1ms, then results from timing operation would be saved in timer parameter list of a dual port RAM, when controller commands need to be executed via PLC, the timer will be used as a regular memory unit for W/R operation, thus no executing time of PLC program would be spared basically, which can well meet the system requirements where large number of controllers are needed. Simultaneously, principles of system composition, timing operation control and timing operation flow are all introduced followed by which a field test is also carried out for testament of the designed timer system.

Abstract:
Studi mengenai kontrol konveyor dan pemrograman menggunakan PLC telah banyak diajarkan di perguruan tinggi khususnya pada bidang Teknik Elektro. Sayangnya materi yang diperoleh peserta didik hanya berupa teori tanpa pengaplikasian secara langsung pada sistem konveyor di industri karena terkendala kebijakan perusahaan. Oleh karena itu, perlu dibuat prototipe sistem konveyor otomatis berbasis PLC yang dimiliki sendiri oleh perguruan tinggi sehingga peserta didik dapat langsung mengimplemetasikan hasil perancangan dan program PLC yang telah dipelajarinya di kelas. Diharapkan dengan adanya prototipe sistem konveyor otomatis tersebut mampu meningkatkan minat dan pemahaman peserta didik terhadap proses otomatisasi industri sehingga akan lebih siap ketika harus terjun langsung ke industri. Penambahan kendali kecepatan pada sistem konveyor otomatis bertujuan utnuk menciptakan suatu prototipe yang sesuai dengan keadaan nyata di lapangan. Penelitian ini membahas perancangan dan pembuatan prototipe sistem konveyor otomatis dengan kendali kecepatan berbasis Programmable Logic Controller (PLC). Perangkat utama pengendali yang digunakan adalah PLC Mitsubishi tipe FX3U yang dilengkapi dengan input analog, output analog, dan output PWM (Pulse Width Modulation). Konveyor yang digunakan adalah konveyor mini dengan penggerak motor DC. Pengendalian kecepatan konveyor dilakukan dengan mengatur kecepatan putaran motor DC menggunakan pengaturan lebar pulsa berbasis PLC.

Abstract:
Nowadays, programmable logic controllers (PLC) are widely used in many automated systems, especially for the control of various actuators. The most common PLC programming is performed by either using a ladder diagram or a structured text. The paper presents the automatic generation of PLC programs for the purpose of sequentially controlling pneumatic actuators. In this paper, the pneumatic actuators are supplied and controlled by 5/2-way as well as 5/3-way bistable pneumatic valves with electric activation. The valve type depends on the number of positions in which the actuator should come, and the position sensors are used for detecting its movement. The characteristic encoding of the movement of actuators, position sensors and control commands is performed. The advantages of the automatic generation of the PLC commands and the entire program described in this paper are illustrated in a real example.

Abstract:
Design of Robust PI Controllers and their Application to a Nonlinear Electronic SystemThe principal aim of the paper is to present a possible approach to the design of simple Proportional-Integral (PI) robust controllers and subsequently to demonstrate their applicability during control of a laboratory model with uncertain parameters through the Programmable Logic Controller (PLC) SIMATIC S7-300 by Siemens Company. The proposed and utilized synthesis consists of two steps. The former one is determination of controller parameters area, which ensures the robustly stable control loop and is based on computing/plotting the stability boundary locus while the latter one lies in the final choice of the controller itself relying on algebraic techniques. The basic theoretical parts are followed by laboratory experiments in which the 3rd order nonlinear electronic model has been successfully controlled in various working points.

Abstract:
Automatic control has been developed in various fields, one of which is paint quality control. Paint quality can be controlled from various categories, including paint quality based on its viscosity. Therefore, we need a system that can control the viscosity of the paint. The paint viscosity control system uses the PLC OMRON CP1E-NA20DRA with a heater as a heat source, and the LM35DZ sensor as a temperature reading sensor, and the RPM reading is used to calculate the viscosity value. The programming language used is the ladder diagram on the CX-Programmer. This system uses the PID (Proportional, Integral, and Derivative) Algorithm so that temperature control can be set at 30ºC so as not to affect the viscosity of the paint. In addition, this prototype provides two PID tuning options, namely manual and auto-tuning. Researchers get the results that a good temperature control system response has a PB value = 0.2%; Ti = 452.5s and TD = 66.6s. and control the accuracy level of paint viscosity control of 67.82%.

Programmable logic controllers are typically programmed in one of the five languages defined in the IEC 61131 standard. While the ability to choose the appropriate language for each program unit may be an advantage for the developers, it poses a serious challenge to verification methods. In this paper we analyse and compare these languages to show that the ST programming language can efficiently and conveniently represent all PLC languages for formal verification purposes. Furthermore, we provide a translation method from IL to ST programming languages (for the Siemens implementation), together with a sketch of proof for its correctness. This allows the usage of the ST-based PLCverif model checking method for safety PLC programs.

The desired motor speed is obtained using two fuzzy inputs namely, the process error and the rate of process error. These fuzzy inputs are feedback data from the motor drive. Different earthquake intensities were used to test the controller’s performance in real time undergoing different load variations. Experiment results showed that the developed controller is accurate, reliable and robust.
