SCADA Training #4 | OPC DA & OPC UA Connection, Certificate Management and Communication
📌 In Lesson 4 of the Wise SCADA training series, we take an in-depth look at OPC DA and OPC UA, the industry-standard communication technologies used for data exchange between SCADA systems and PLCs. Wise SCADA includes many built-in (native) drivers. However, when you need to communicate with devices that are not natively supported or that use proprietary protocols, OPC technology becomes essential. In this lesson, you will learn how to connect to external devices using both classic OPC DA and modern OPC UA, how to establish secure data communication, and how to manage certificates step by step.
