Automation Laboratory Development With Design Implementation Scheme and Simulation Software

This paper describes the development of the Automation Control Lab in the Mechanical Engineering Technology Program of the Engineering Technology Department at Old Dominion University. The reorganization goal of the development is to help students design, test, and implement their automation designs effectively. Three processes are adopted to achieve this goal: (1) floor-plan design and inventory control of the components, (2) using Automation Studio to dynamically check each design, and (3) using industrial Programmable Logic Controllers (PLC) controllers to download PLC programs

Securing Industrial Control Systems: Components, Cyber Threats, and Machine Learning-Driven Defense Strategies

Article describes how Industrial Control Systems (ICS), which include Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and Programmable Logic Controllers (PLC), play a crucial role in managing and regulating industrial processes. This article presents an overview of ICS security, covering its components, protocols, industrial applications, and performance aspects

USER REQUIREMENT SPECIFICATION (URS) AND PROGRAMMABLE LOGIC CONTROLLERS (PLC) PROGRAMMING DESIGN AT CARTRIDGING PROCESS PT DAHANA (PERSERO) PROPOSAL

ABSTRAKSI: Industrial automation is rapidly growth nowadays. With the industrial automation, the industry can level up their production level. To avoid the number of high investment while leveling up the company production using automation it needs a way to assure it. One way to do it is to design the User Requirement Specification (URS). The User Requirement Specification specify the needs of the end user for the automation system. URS describe from the process description, the piping and instrumentations diagram, and the control philosophy. The process description describe about how will the automation process happened in the company. The piping and instrumentations diagram (P&ID) depict about how is the layout and the instrumentations interact between each other according to the process description. As for the control philosophy describe about the hardware specification for the process automation. To integrate the automation system designed, the programmable logic controllers (PLC) programming is needed. The plc would act as the automation process controllers. The way the instruments interact to each other would be controlled by the PLC. The PLC control the designed automation process in Cartridging Process PT Dahana (Persero). The cartridging process consists of 4 work stations : cartridge labeling, cartridge piping, cartridge filling, and product sorting and packaging. The automation process designed in only cartridge labelling and cartridge filling workstation. From the research conducted it can be concluded that the design for User Requirement Specification (URS) and the Programmable Logic Controllers (PLC) program for cartridging process in PT Dahana (Persero) is successfully designed. The design resulted in process description, piping and instrumentations diagram, control philosophy, and programmable logic controllers program.KATA KUNCI: Automation, Cartridging Process, Control Philosophy, Piping an Instrumentation Diagrams, Process Description, PLC, URS.ABSTRACT: Industrial automation is rapidly growth nowadays.

Enabling industrial scale simulation / emulation models

OLE Process Control (OPC) is an industry standard that facilitates the communication between PCs and Programmable Logic Controllers (PLC). This communication allows for the testing of control systems with an emulation model. When models require faster and higher volume communications, limitations within OPC prevent this. In this paper an interface is developed to allow high speed and high volume communications between a PC and PLC enabling the emulation of larger and more complex control systems and their models. By switching control of elements within the model between the model engine and the control system it is possible to use the model to validate the system design, test the real world control systems and visualise real world operation. <br /

Integration of Evora-InovGrid Smartmeters in a Consumer’s SCADA System

This paper develops an energy management system with smart meters integration for electricity consumers in a smart grid context. The integration of a distributor owned smart meter from the main Portuguese electricity distributor – EDP - is developed. The smart meter is connected to a common PC, that runs the Matlab Software and communicates to the SCADA system (Supervisory Control And Data Acquisition) using the OPC Protocol. The SCADA system supervises an industrial network of Programmable Logic Controllers (PLC). The developed control strategy implements a hierarchical cascade controller where inner loops are performed by local PLCs and the outer loop is managed by a centralized SCADA system, which interacts with the entire local PLC network
