In the past, Lenze used to rely on the OPC Classic to enable access to device data. However, as this standard no longer covers advanced requirements, the company opted for the development of an OPC UA Server. This was achieved using a Toolkit from Softing. Also, Softing’s new white paper discusses OPC UA Publisher / Subscriber communication for IIoT and outlines details on a proof-of-concept implementation.
DCI Technologies needed a reliable method for tapping into their radios’ serial diagnostics data remotely so that troubleshooting could occur without having to visit each individual site. To meet the end goal of providing an open solution, they considered several rapid protocol modeling solutions providing standard interfaces such as OPC DA, OPC UA and DDE. In the end, their chosen solution was the OmniServer OPC and I/O Server from Software Toolbox.
FLIR Intelligent Transportation Systems develops a wide variety of hardware and software solutions for vehicular/pedestrian traffic video detection and monitoring. Very often, these systems rely on open standard OPC UA interfacing to obtain information from the different subsystems.
OPC is being used in the production of electricity with zero emissions. PROGEA is one of the companies that participated in the technology innovation project called Enerclean, coordinated by the Department of Science and Engineering, University of Modena & Reggio. The project involves the production of clean energy and hydrogen through the natural process of combustion of aluminum powder on contact with water. The goal is to get a high efficiency energy system with near zero environmental impact.
Recently, a large manufacturer of raw materials for the power generation industry needed to accomplish what would seem to be a relatively straightforward task – to gather comprehensive temperature and humidity data across facilities where vacuum furnaces operate to harden materials. The engineer discovered that an OPC Server for consuming RESTful JSON web services would easily facilitate consuming the required data in real-time and exposing it via OPC.
The City of Enid, Oklahoma is located 70 miles North of Oklahoma City. The city’s water management services include production, distribution and reclamation. It includes approximately 140 producing underground water wells with 200 miles of collection lines, 23 million gallons of storage tanks, seven pumping stations and two treatment plants. The department wanted a solution that easily integrated with OPC UA standards and could handle over 1,400 tags.
ABB was selected as the main automation contractor for the world’s first operation focused on converting gas from coal seams into liquefied natural gas. With several new wells being introduced every day, ABB needed to be able to bring them on and off line in a highly streamlined and efficient manner; furthermore, the method of configuring them needed to be simple, fast, and very reliable.
OPC UA paves the way for the implementation of new concepts with increased vertical and horizontal data integration, and opens the door to industries requiring seamless data logging. Supporting use in both PCs and embedded systems, OPC UA technology allows the implementation of solutions that move intelligence from the supervisory control systems to the local components.
After evaluating further options and a proof-of-concept using a test implementation, SST and DB Netz AG made a joint decision to use OPC UA for implementing the client-server communication, because OPC UA met all requirements. An OPC UA information model was developed, which was able to reproduce the complex data structures of diverse diagnostic information.
