OPC UA Wrapper Archives

In the ever-evolving landscape of industrial automation, OPC has long served as the foundation for communication between devices and systems. As industries progress, the demand for communication standards has evolved, leading to a transformation of OPC standards to meet the industry’s growing needs. While the once-revolutionary OPC standard was robust in its time, it has faced challenges in meeting modern industrial requirements. With the increasing demand for industrial cybersecurity, flexible data modeling, and platform independence, original equipment manufacturers (OEMs) and software development companies are adopting OPC UA as their preferred protocol. This shift has led industrial end-users to use OPC UA instead of OPC Classic. So, it is essential to highlight the disparities between OPC Classic to OPC UA Key differences between OPC Classic and OPC UA OPC UA offers significant improvements in security, platform independence, data modeling, and interoperability compared to OPC Classic. These include: 1- Security Based on Microsoft’s COM/DCOM technology from the nineties, OPC Classic historically lacked security features in terms of encrypted communications, minimum TCP ports, and support of distributed network architectures using several domains, firewalls, and DMZ. OPC UA prioritized security with built-in encryption and authentication mechanisms as well as configuration communications parameters, thus ensuring a more secure framework for industrial communications. 2- Platform Independence OPC Classic is tied to the Windows operating system, facing challenges in integrating with diverse platforms. OPC UA on the other hand is designed for platform independence, enabling seamless communication across various operating systems including Windows, macOS, Android, and Linux. It can also be used on embedded systems allowing automation device suppliers to embed OPC UA into their PLCs and RTUs. 3- Data Modeling While OPC Classic is very limited in representing complex data structures as it uses tag-based address spaces, the OPC UA supports sophisticated representation of industrial data and complex structures, facilitating a richer exchange of information. OPC UA defines an integrated address space and an information model in which process data, alarms, historical data, and program calls can be represented. While using OPC UA in new implementations of automation systems and software products, supporting OPC UA in existing automation installations, devices, and software remains a challenge. Options to migrate from OPC Classic to OPC UA with minimum budget and architecture changes are required. Introduction to OPC UA Wrapper: The OPC UA Wrapper acts as a plug-and-play bridge between OPC Classic and OPC UA, facilitating the coexistence of both protocols. Comprising an OPC UA Wrapper and an OPC UA Proxy, the software streamlines the integration process, allowing organizations to transition smoothly to OPC UA with minimum system changes.
