Dear OPC UA Enthusiast,
we are pleased to present our quarterly Unified Automation Newsletter.
As promised we keep you informed about new product releases and tools we develop
at Unified Automation GmbH. From the very successful "OPC Day Europe" at SAP in
Walldorf, Germany we learned that a lot of activity is taking place around OPC
UA development. Looking back the last few months we are very satisfied with the
adoption of OPC UA and all the upcoming UA enabled products.
To establish an active support community and to offer you an additional support
channel we started our own UA forum in the Developer-Zone of our website. For
trouble shooting and analysis of OPC UA on the wire, a new dissector plug-in was
released with Wireshark V1.6.0.
In addition we want to inform you about our new service release V1.2.1 of the
ANSI C based OPC UA SDK which now includes a tutorial for using Alarms&Conditions.
There is a free evaluation version of this OPC UA SDK available for download.
Stay tuned on OPC UA. Hope you enjoy reading.
Yours sincerely
Jürgen Boxberger
CEO Unified Automation GmbH
Service Release V1.2.1 for ANSI C based OPC UA Server SDK
Besides some cumulative minor bug fixes we collected over the last year the main
improvements are in the Alarms&Conditions functionality. Here we added a new
example and a tutorial explaining how to best use this feature. We added comfort
functions for Condition handling that will make developers life much easier.
In addition the session handling capabilities were improved and we added a clock
change detection. Now publish and session timeouts due to clock changes can be
avoided.
A detailed description of features, bug fixes and changes and the documentation are online on our website at
doc.unifiedautomation.com
Again there is a fully functional
evaluation demo available for download from our website.
Developer Forum started
We just launched the new developer forum on our website
(http://www.unifiedautomation.com/forum).
The forum can be accessed with your Unified Automation login. If you don't have
an account yet, just click "Register" on the forum start page.
There are already informative sections with FAQs and How-Tos and we will add more
content over time. We want to provide a valuable source of knowledge for you
while working with our SDKs or the free evaluation demos. We encourage you to
ask and answer questions. Our goal is to build up an active community and a
knowledgebase for the use of OPC UA and our products and tools.
Wireshark 1.6.0 supports OPC UA
The well known network analyzer Wireshark (formerly Ethereal) was enhanced with a
dissector plug-in that can decode OPC UA. The plug-in was donated by ascolab GmbH
and is capable of displaying TCP based UA Binary messages. Wireshark's new
version 1.6.0 includes the UA plug-in by default and is a must for all developers,
system testers and integrators when it comes to trouble shooting on the wire.
