OPC Unified Architecture (OPC UA) Server

The OPC Unified Architecture (UA) Server Interface for ThingWorx Kepware Edge provides client applications (such as MES, SCADA, or Industrial IoT solutions) seamless and secure access to industrial automation data. ThingWorx Kepware Edge allows the server to be deployed in flexible and secure Linux environments. 

OPC UA is a modern communications protocol for industrial automation and has been adopted by many industrial applications. It is also used in a wide variety of Industrial IoT solutions, and the Industrie 4.0 Platform requires "Industrie 4.0-enabled products" to use OPC UA for communication. As an open standard, it enables interoperability in heterogeneous environments. 

OPC UA offers built-in security through certificate exchange and point-to-point encryption methodologies. When used in conjuction with native Linux tools, ThingWorx Kepware Edge keeps your data safe and enables you to easily troubleshoot client and server communication issues.

What is an interface?

ThingWorx Kepware Edge allows the most valuable features of KEPServerEX to be deployed in Linux-based environments. It offers users flexible deployment of valuable Kepware functionality and native connectivity to ThingWorx, the leading Industrial IoT platform.

An interface is a software component that enables ThingWorx Kepware Edge to meet the connectivity requirements of a specific client application. Interfaces handle all supported connectivity to applications that monitor or control devices; drivers handle all proprietary communications to devices.
