OPC UA technology allows applications distributed on different hardware platforms to be unified with a common information backbone. OPC UA is a secure, platform-independent, scalable, and object-oriented architecture for representing and communicating information. By using OPC UA, information can be modeled so that applications can inherently derive its meaning and consequently make better decisions based on that meaning. This enables applications to gain intelligence that can lead to new and exciting outcomes in data management. In addition, OPC UA provides a mechanism to protect the confidentiality and integrity of information and to determine whether applications are trustworthy--a fundamental need of the Industrial Internet. This paper will provide an overview of the OPC UA and how it is used within IICS to generate beneficial outcomes for customers.
