Overview

OPC Unified Architecture (OPC UA) is the next generation of the familiar OPC standard. This is a globally standardized communication protocol via which machine data can be exchanged irrespective of the manufacturer and platform. OPC UA already integrates common security standards directly in the protocol. Another major advantage of OPC UA over the conventional OPC standard is its independence from the COM/DCOM system.

Overview 1:

Detailed information on OPC UA can be found on the web pages of the OPC Foundation.

The TwinCAT 3 Function TF6100 OPC UA consists of several software components that enable data exchange with TwinCAT based on OPC UA.
The following table provides an overview of the individual product components.

Software component

Description

TwinCAT OPC UA Server

Provides an OPC UA Server interface so that UA clients can access the TwinCAT runtime.

TwinCAT OPC UA Client

Provides OPC UA Client functionality to enable communication with other OPC UA Servers based on PLCopen-standardized function blocks and an easy-to-configure I/O device.

TwinCAT OPC UA Configurator

Graphical user interface for configuring the TwinCAT OPC UA Server.

TwinCAT OPC UA Sample Client

Graphical sample implementation of an OPC UA Client in order to carry out a first connection test with the TwinCAT OPC UA Server.

TwinCAT OPC UA Gateway

Wrapper technology that provides both an OPC COM DA Server interface and OPC UA Server aggregation capabilities.

This documentation describes the TwinCAT OPC UA Configurator, which is an engineering software component that provides a graphical user interface for configuring the TwinCAT OPC UA Server. The TwinCAT OPC UA Configurator is delivered in two variants: an interface integrated into Visual Studio (or the TwinCAT XAE Shell) and a standalone tool. Both variants have the characteristic that you establish an OPC UA communication connection to a TwinCAT OPC UA Server and configure the server via this connection. The basis for this is the so-called configuration namespace of the TwinCAT OPC UA Server, which provides all relevant configuration files for authenticated users via OPC UA.
