Abstract

The main goal for our study is the design, implementation, and empirical test of the physical and software model of an OPC-based SCADA system comprising multiple industrial controllers of various commercial brands. In this study, an electro-pneumatic press prototype was prepared with four different PLCs, an open-source controller and an operator panel which have different industrial communication protocols. Each sub-task of the pressing unit was assigned to different industrial controllers, and the network infrastructure of the SCADA system was created with a star topology and taken into operation. The connectivity and interoperability for the designed networked system comprising significant number of devices with different industrial communication protocols was effectively provided. OPC-based SCADA system was tested in runtime mode and the controllers successfully talked to each other through the system. The hardware and software structural details, possibl1e malfunctions and data transmission speeds of the system were analyzed and shared.

OPC Tabanlı SCADA Sisteminin Tasarımı, Uygulama ve Analizi

Abstract

Çalışmamızın ana amacı, çeşitli ticari markaların çoklu endüstriyel denetleyicilerini içeren OPC tabanlı bir SCADA sisteminin fiziksel ve yazılım modelinin tasarımı, uygulanması ve deneysel testinin yapılmasıdır. Bu çalışmada, farklı endüstriyel haberleşme protokollerine sahip dört farklı PLC, açık kaynaklı denetleyici ve operatör paneli ile elektro-pnömatik pres prototipi hazırlanmıştır. Pres ünitesinin her bir alt görevi farklı endüstriyel denetleyicilere atanmış ve SCADA sisteminin ağ altyapısı bir yıldız topolojisi ile oluşturularak devreye alınmıştır. Farklı endüstriyel iletişim protokollerine sahip önemli sayıda cihazdan oluşan tasarlanan ağ bağlantılı sistemin bağlanabilirliği ve birlikte çalışabilirliği etkin bir şekilde sağlanmıştır. OPC tabanlı SCADA sistemi çalışma zamanı modunda test edilmiş ve denetleyiciler sistem üzerinden birbirleriyle başarılı bir şekilde haberleşmiştir. Sistemin donanım ve yazılım yapısal detayları, olası arızaları ve veri aktarım hızları analiz edilerek paylaşılmıştır.
