The benefits of using OPC specification design systems:
With standard Windows system interfaces, hardware manufacturers have reduced the number of interface programs provided by their devices to one, and software manufacturers also only need to develop a set of communication interface programs. That is, it is conducive to software and hardware developers, more beneficial to end users. The OPC specification is based on OLE / DCOM, while OLE / DCOM supports network protocols such as TCP / IP, so that individual subsystems can be physically separated from different nodes of the network. OPC is encapsulated by an application (OPC server) as an object-oriented principle, and only the interface method is exposed to the outside, and the customer calls this method in a unified manner to ensure the transparency of the software to the customer, so that users It is completely detached from the low-level development. The OPC implements remote calls that make the application's distribution of the system-hardware distribution, which makes the system hardware configuration, making the system's application range. Using OPC specification, it is easy to configure the system, which greatly simplifies system complexity, which can greatly reduce software development cycles, improve software operation reliability and stability, and facilitate the upgrade and maintenance of the system. The OPC specifies the interface function, regardless of the form of on-site equipment, customers access to the unified manner, thereby achieving the openness of the system, which is easy to implement interfaces with other systems.
