OPC UA

Open process communication unified architecture

The modern evolution of the OPC standard, redesigned to be platform-independent, robust, and secure. OPC UA is a communication protocol that allows various industrial devices and software to share data in a unified way. It is more commonly found at the higher levels of the network and can use a binary TCP format or HTTPS format. Unlike OPC Classic, it’s not tied to Windows COM, and it includes built-in security (encryption, authentication).
