OPC Industrial Control Interface



OPC, OLE for Process Control, was introduced to bridge Windows-based applications and on-site process control applications. In the past, every application developer needed to write a dedicated interface function in order to access the data of on-site devices. Due to the variety of field devices, and the continuous upgrading of products, users and software developers often bring tremendous workload. This usually cannot meet the actual needs of the work, system integrators and developers in urgent need of a highly efficient, reliable, open, interoperable plug-and-play device drivers. In this case, the OPC standard came into being. The OPC standard is based on Microsoft's OLE technology and is developed through the provision of a standard OLE / COM interface. OLE 2 technology is used in OPC technology. The OLE standard allows multiple computers to exchange documents, graphics and other objects.


Through DCOM technology and OPC standards, it is entirely possible to create an open, interoperable control system software. OPC adopts the client/server mode, puts the task of developing the access interface to the hardware manufacturer or the third-party manufacturer, and provides the OPC server with the form of OPC server to solve the contradictions between software and hardware vendors, complete the system integration and improve the system Openness and interoperability.


The OPC server usually supports two types of access interfaces, each providing access mechanisms for different programming language environments. These two interfaces are Automation interface and Custom interface. Automation interfaces are typically standard interfaces defined for scripting languages and can be used to develop client applications for OPC servers using programming languages such as Visual Basic, Delphi, and PowerBuilder. Custom interfaces are standard interfaces designed for high-level programming languages such as C++. OPC has now become the default solution for interconnecting industrial systems and has facilitated industrial monitoring programming without the user having to worry about communication protocol challenges. Any provider of automated software solutions, if it can not fully support OPC, it will be eliminated by history.


To enable automated devices to work with Taichen VMS platform, Industrial Enterprise Edition supports Tens of thousands sensors to access real-time sensor data published through the OPC standard to trigger Automated Business Processes Control Systems, And provide effective proprietary data to automation control systems and VMS platform.
