There are a few products that are short-lived, but it’s much more common to build production processes for diapers, soap, tea and hundreds of other products that we’re going to run for the next five, ten or twenty years. In this industry, we generally build automation processes to last. Microsoft has a well-deserved negative reputation, especially in Industrial Automation. Not Linux, not VxWorks, not anything else. COM, the base technology for OPC, is a Microsoft product. The other problem is the deficiencies that come with dependency on Microsoft and Windows. Management didn’t have a certification program in place to ensure that the people maintaining OPC Servers were well trained in COM and DCOM and troubleshooting OPC Server problems. The problem is that management didn’t dictate that a checklist is in place when an OPC Server stops communicating. The lack of COM/DCOM knowledge and the seemingly inconsequential act of plugging in a data stick are not OPC Classic problems.

How you use it, configure it and set up authorizations varies slightly from one version of Microsoft Windows to the next. Why? COM and DCOM (distributed version of COM) are difficult to maintain and understand without significant training. However, not long after its invention, the application demands, and a changing automation landscape began to erode the acceptability of PCs and OPC Servers in these applications.

For the first time ever, systems integrators and other factory floor application developers could implement applications without spending vast sums on driver development. This was revolutionary and probably accelerated the adoption of PCs on the factory floor. Data from the device, no matter what physical layer or protocol it supported, could be read or written by any Microsoft application that supported COM. The OPC founding fathers took this technology mated it to an API that supported device protocols for automation devices, and OPC 1.0 was born. One application could request data, and another would supply it. It provided a way for Microsoft Windows applications to share data. COM was a newer Microsoft technology at the time. Their solution centered on COM (Component Object Model). Their mission was simple: create a way for applications to get at data inside an automation device without having to know anything about how that device works. Their work eventually led to the OPC 1.0 and the creation of the OPC Foundation. Integration with Standard Industry-Specific Data Models – The OPC Foundation is working with several industry trade groups that define specific Information Models for their industries to support those Information Models within UA.Īround 1994-1995, a bunch of factory automation experts got together and decided there had to be a better way to operate their factory floor applications.The Alarming and Event mechanisms go well beyond the standard change-in-value type alarming found in most protocols. Sophisticated Alarming and Event Management – UA provides a highly configurable mechanism for providing alarms and event notifications to interested Clients.OPC UA is designed to connect Objects in such a way that true Information can be shared between Clients and Servers. A Sophisticated Information Model – OPC UA profiles more than just an Object Model.Certified Interoperability – OPC UA certifies profiles such that connectivity between a Client and Server using a defined profile can be guaranteed.

A Robust Set of Services – OPC UA provides a full suite of services for Eventing, Alarming, Reading, Writing, Discovery and more.

Internet Capability – OPC UA is fully capable of moving data over the Internet.

Security – OPC UA implements a sophisticated Security Model that ensures the authentication of Client and Servers, the authentication of users and the integrity of their communication.

Common Transports and Encodings – OPC UA uses standard transports and encodings to ensure that connectivity can be easily achieved in both embedded and enterprise environments.

Objects are entities that consist of Variables and Methods and provide a standard way for Servers to transfer information to Clients.

A Flexible Address Space – The OPC UA Address Space is organized around the concept of an Object.UA uses discoverable profiles to include tiny embedded platforms as Servers in a UA system. It can be supported on high-end Servers and on low-end sensors. Scalability – OPC UA is scalable and platform-independent.Feature of this unique technology include: OPC UA is a sophisticated, scalable and flexible mechanism for establishing secure connections between Client and Servers.
