Welcome

As we get further into 2017 we continue making great strides with OPC technology and marketing activities. Stefan Hoppe and I continue to go out and evangelize the OPC UA technology at a multitude of different events the world over. Just in the months of April and May I have been in five different countries presenting and talking about the limitless applications of OPC UA.
Thank you for taking the time to read this June edition of our OPC Connect newsletter!

There Is No Industrie 4.0 without OPC UA

The Industrie 4.0 Platform published a checklist for classifying and advertising products as Industrie 4.0 “Basic”, “Ready” or “Full”. To comply with the “Industrie 4.0 communication” criterion, even the lowest category requires a product to be addressable over the network via TCP/UDP or IP and to integrate at least the OPC UA information model. As a result, any product being advertised as “Industrie 4.0-enabled” must be OPC UA-capable (either integrated or via a gateway).

The State of Things

Clearly, all the efforts around a reliable and flexible implementation of Industrial Internet of Things (IIoT) and Industrie 4.0 have prompted the research of many different ways to exchange information among industrial systems. And once again, the advantage of the OPC UA design is that – since its inception and for its very nature – it is a specification that can fit more than one scenario and does not constrain innovation but enables it.

Evolution of Pub/Sub and Gateway Software Push IIoT Further

Those who can remember the early days of Internet workings might be familiar with the Publish-Subscribe method of electronic messaging. It is due to the emergence of the Industrial Internet of Things (IIoT) that we have returned to the pub/sub method as a best practice standard for data transmission. IoT gateways provide a bridge between an on-premises communications network and a cloud-based one.

Turning Wonderware System Platform into an OPC UA Server

Have you ever been in a situation where you were working with both Wonderware and some other client (HMI, SCADA, other) and needed to share data? Well, in the practical, real world, having clients from more than one vendor is a reality of existence in the process/control world. Essentially, this article tells you how to turn your Wonderware system into an OPC UA Server.

TwinCAT OPC UA: Standardized Communication with Information Modeling

As a long-term active partner of the OPC Foundation, Beckhoff was among the earliest adopters to implement the OPC UA standard in many innovative ways. After enabling the standardized exchange of data via OPC UA for many years, it has become even better with additional new features that improve the modeling of systems, security, and usability.

Data is the New Currency

A central challenge of Industrie 4.0 and the Industrial Internet of things (IIoT) is secure standardized data and the exchange of information between devices, machines, and services from various industries. The OPC UA standard is the only mandatory protocol required in the criteria checklist of “Product capabilities for Industrie 4.0 Products” provided by the German Industrie 4.0 Platform.

Secure OPC UA Connectivity

Managing security certificates is one of the most important parts of establishing an OPC UA connection. Cogent’s DataHub makes it easy to accept or reject certificates using its built-in management tool. Plus with its latest release, they’ve added the ability to act as both an OPC UA Client and Server.

President’s Welcome

2016 was a outstanding year with all the new collaborations and extensions to the OPC UA technology. 2017 will significantly exceed the success of 2016! OPC UA technology development is well underway for the publish/subscribe architecture which will further extend information integration and system wide interoperability from the embedded world to the enterprise. From an event perspective, the OPC Foundation is hosting many of its own events and participating in a multitude of tradeshows internationally.
We’ve expanded the newsletter program from four newsletters in 2016 to doing six newsletters in 2017 because of the volume of information and making sure that we are providing the latest and greatest timely information. Thanks again for taking time out of your busy day to read this edition of the OPC Foundation OPC connect newsletter.
