Utgard 0.1.8 is out which features a new version of j-Interop that solves the array writing issues that we had in the last releases. Also the we have a new interface mapped: the IOPCServerList (aka OPCEnum). So it is now possible to browse for OPC services using Utgard. Also there were some enhancements in the “lib” module which should ease the access using the browser interfaces.

In the last months there were also a lot of tests made with different OPC Server (Kepware, Moeller, rslinx) and most of them worked perfectly. Thanks to all testers and of course thanks to Vikram for solving the array issue in j-Interop!!

Those who don’t should have a look at it, you are really missing something ;-) The new NXT version of Lego Mindstorms has quite some interesting features: a 32bit CPU, bluetooth and USB connectivity, new sensors (like ultrasonic distance measuring), an open source firmware and lots more. Of course this screams for some OpenSCADA integration ;-) … so here it is: MindstormsProject

Most notably there is now an option to handle multiple windows at the same time together with a view link button:

Viewer 1

The main view is scrollable and the Draw2D layout stuff has been cleaned up a little bit. So now it is possible to set opacity, background color, command buttons, popup menus and lots more.

Based on JFreeChart we added a online charting view for data objects. The plugin is already available in the integration builds and will be available with the upcoming release 0.8.0 of project Atlantis.

The most notable changes are a new version of J-Interop (thanks to Vikram!) which solves some issues with the JIVariant encoding/decoding and some connection issues. Also the helper library “openscada_opc_lib” has some new functionality that helps you a little bit.

As promised after the release 0.6.0 of project Atlantis we will see some fun with the .NET platform. The ICE framework made it quite easy to provide access from .NET to the already exisiting Java Components from project Atlantis. The result for today is a class library including OpenSCADA DA Client functionality on the one side and a little DA Client Sample which was created mostly with the Forms Editor of “Visual C# Express”.

To see the preview just follow the link with IE. Of course using Firefox, Safari, [your browser here] is not a big deal. But the tight integration of .NET into IE makes it a bit more comfortable. Since this is not a release but a preview it should be fine ;-) Anyway you can download a seperate source and/or binary package here.

For details about the release and the download links see the wiki (AtlantisVersion060). This release features mostly back-end enhancements and only minor GUI tweaks were made. Most important enhancements are:

  • New Communication Adapter (ICE Framework)
  • Generalization of Client Interface (independent of connector implementations)
  • A new build system that is much less static
  • Contains the OPC Server based on Project Utgard

This gives OpenSCADA a new object oriented communication interface beside the already implemented socket protocol. The integration builds already contain the ICE specific modules. There is still work to be done but ICE will be part of the soon to be released version 0.6.0. For details on ICE and the OpenSCADA ICE Connector read on …

The major change is a new version of the library j-interop (thanks to Vikram) which fixes some issues in the DCOM protocol handling. Together with some minor bug fixes this gives a new version which can now handle async IO 2.0 connections with Matrikon and Softing OPC servers and support browsing with much larger batch sizes.
