Utgard is a vendor-independent, 100% pure JAVA OPC Client API, that can be used independently from other OpenSCADA projects.

It provides functions which enable connection to an OPC Server, currently supporting the interface of OPC DA 2.0.

Utgard is used in OpenSCADA in combination with Atlantis to connect to and communicate with 3rd party systems via OPC.

Currently the project consists of two libraries:

openscada-opc-dcom

The direct DCOM Wrapper providing plain OPC DA functionality in Java

openscada-opc-lib

A helper library, simplyfing the complexity of the OPC interface from openscada-opc-dcom

100% Open Source

The whole project is available under an open source license including the required 3rd party libraries. The Utgrad Project itself is licensed under the GPL (unless noted otherwise).

100% pure Java

The Utgard Project requires no more than an up to date Java environment (Java 1.5.x+). No native code, no JNI libraries or other DLLs/shared libraries are required. This makes it a 100% pure Java project.

This way, it is possible to connect to an OPC server running on Windows directly from your application, regardless of which operating system (Unix/Linux/Mac OS) your application is running on.

Due to the fact that currently only the OPC DA client side is implemented you will need some OPC server. Although some solutions for Unix/Linux/... exist you will usually find OPC servers based on Windows. So up to now the Utgard Project cannot help you running OPC servers on non-windows operating systems.

What Utgard can do for you

Provide you with OPC Client Mappings in pure Java

Help you create OPC Client Applications in pure Java

What Utgard cannot do

Port existing OPC Servers or Clients to Java/any other OS

Create OPC servers in Java (this is planned but currently not implemented)
