This paper investigates the implementation and design of a fuzzy system on an industrial controller. Programmable Logic Controllers (PLCs) are key devices used in many industrial processes. Most of the time they implement discrete control functions involving sequential control, but the availability of basic features like arithmetic operations, floating point units etc. allow for more complex al...

A RIKEN 18 GHz electron cyclotron resonance ion source (18 GHz ECRIS) is used as an external ion source at the Radioactive Ion Beam Factory (RIBF) accelerator complex to produce an intense beam of medium-mass heavy ions (e.g., Ca and Ar). In most components that comprise the RIBF, the control systems (CSs) are integrated by the Experimental Physics and Industrial Control System (EPICS). On the ...

World factory instrumentation protocol (WorldFIP) is a fieldbus network protocol that provides a link between level zero (sensors/actuators) and level one (field controllers such as programmable logic controllers, etc.) in industrial automation systems. Accessing and connecting the WorldFIP remotely is important for monitoring, maintaining, and controlling devices in a factory in which asynchro...

For direct process control are most frequently used control systems based on PLCs (Programmable Logic Controllers), industrial controllers and other standard control systems. Applications based on standard industrial control systems and industrial serial networks are usually too expensive for small and very small application. For that reason has been proposed and developed small, highly modular...

The supervisory control theory is a general theory for automatic synthesis of controllers (supervisors) for discrete event systems, given a plant model and a specification for the controlled behavior. Though the theory has for over a decade received substantial attention in academia, still very few industrial applications exist. The main reason for this seems to be a discrepancy between the abs...

This paper presents an integrated on-line learning system to evolve programmable logic array (PLA) controllers for navigating an autonomous robot in a two-dimensional environment. The integrated online learning system consists of two learning modules: one is the module of reinforcement learning based on temporal-di erence learning methods, and the other is the module of evolutionary learning ba...

This paper addresses the problem of verifying the discrete control logic that is typically implemented by programmable controllers. Not only are the logical properties of the controller studied during verification, the behaviour of the overall controlled system is also examined. An approach that combines the calculation of the safety-oriented interlock controllers in terms of supervisory contro...

Rapid advances have been made in Commercial Off-The-Shelf Programmable Logic Controllers (PLCs), PC-based boards and embedded intelligence in localised smart controllers, smart sensors and smart actuators. Great opportunities exist to produce high performance, dependable distributed systems, however, the key element that is missing is software tool support for systems integration. Many propriet...

Dengan berkembangnya teknologi di dunia industri maka semakin banyak inovasi-inovasi terbaru yang dapat mempermudah proses produksi industri. Proses pengemasan telur adalah salah satu dikembangkan dalam pengelolahannya yaitu dengan cara menggunakan program pada PLC. PLC (Programmable Logic Controllers) merupakan sebuah sistem pengendali untuk menjalankan suatu rangkaian.. Biasanya secara manual...

AbstructDesign methods for sequence controllers play a very important role in advancing industrial automation. The increasing complexity and varying needs of modern discrete manufacturing systems have challenged the traditional design methods such as the use of ladder logic diagrams (LLD’s) for programmable logic controllers. The methodologies based on research results in computer science have ...
