OPC UA stands for OPC Unified Architecture. It is an extensible, platform-independent standard that enables the secure exchange of information in industrial systems. In 2008, OPC UA was released by the Open Platform Communications (OPC) Foundation, which regulates and maintains the interoperability standard, protocols, and specifications for ...

OPC UA PubSub communication can be transmitted via UDP or directly on layer 2. Depending on the technology used, this can result in short cycle times. In conjunction with Time-Sensitive Networking (TSN), OPC UA PubSub therefore enables real-time communication at the control level and meets the demands of time-critical applications.

Open Platform Communications – Unified Architecture (OPC UA) was developed by the OPC Foundation, which was created in 1996 with Siemens as a founding member. The OPC Foundation is an international nonprofit organization with over 450 members from all sectors of industry.
OPC UA with client/server communication is used extensively in automation. With this proven, one-to-one communication mechanism , each OPC UA client obtains access to the data on the OPC UA server via point-to-point communication. The OPC UA client sends a request to the OPC UA server, from which it receives a response. This form of communication enables a reliable, secure, encrypted data exchange with reduced bandwidth and no loss of data, even if the environment and network quality are sub-optimal and are experiencing disturbances. Client/server communication is always based on TCP/IP.
Guaranteed, scalable bandwidths, optimized Quality of Service (QoS) mechanisms, real-time capability, and very low transmission latency in communication networks: Siemens relies on Time-Sensitive Networking (TSN) to get the most out of automation networks while meeting constantly growing requirements. As a result, communication from machine to machine and from machine all the way up to the operator level can achieve new heights in terms of speed and reliability. TSN is defined within the framework of IEEE 802.1 and combines a series of individual standards that affect only the data-link communication layer (layer 2).
OPC UA is very effective in situations where a sub-system (remote terminal or piece of equipment ) has to utilize a supervisory system during a discrepancy. As OPC UA utilizes standard ethernet communications, any physical layer – including wired, wireless and satellite – can be used to transmit OPC UA messages. This feature can also be extended to systems that require constant or periodic reporting.
For any manufacturing process to be industry 4.0 capable, it also has to be OPC UA capable. The most quintessential element for using OPC UA to enable industry 4.0 driving communication is an internet protocol (IP) based network. Internet protocol and OPC UA form the flesh and blood of an industry 4.0 capable manufacturer.
Blackboard™ is the online Learning Management System used in almost all courses at the University. Via Blackboard course sites, professors manage class resources, post assignments and communicate with students. It is important to check your Blackboard account regularly.
If you are unfamiliar with Blackboard or are experiencing problems navigating the platform, we suggest that you take a look at the Blackboard FAQ for students or watch the video tutorials.
If you are teaching with Blackboard, you may use the links below for frequently asked questions and video tutorials. For training sessions or further assistance, please contact [email protected].
The OPC Server is the basis of OPC communication. It is a software that implements the OPC standard and thus provides the standardized OPC interfaces to the outside world. Inside, the proprietary communication protocol for controlling the manufacturer is implemented. OPC Servers are provided by different parties.
It is the successor of the old OPC standard, which is called OPC Classic. Many installations of OPC servers are Classic OPC Servers until today. The old standard already very successfully solved the task of realizing data exchange in automation independent of the manufacturer and defined the basic interfaces.

Using the Historical Access specification, it is possible not only to read data with the current value, but also to query historical values. An OPC server that implements this specification must have an internal data memory in order to provide the values of the data points for possible historical accesses.
The XML format, which was emerging at that time, was used in connection with web technologies. In 2003, the OPC XML specification was released. Three years later, in 2006, however, the first version of OPC UA was already available, making OPC XML obsolete.
