OPC is an organic photoconductor (Organic Photoconductor) abbreviation. OPC Drum is the use of OPC in the conductive material coating the surface of aluminum tube and the formation of a Media Converter pieces, which is characterized by an insulator in the dark is, to maintain a certain degree of electrostatic charge, when a certain wavelength of light irradiated into the conductors, the release of charge through the aluminum to form a electrostatic latent image, it is a laser printing, digital copies of the core components. Do not touch the OPC drum surface by hand rather than using chemical reagents (such as alcohol) to clean the surface of OPC drums, do not use a hard object collision OPC drum surface.
Two,
1, in the control areas, systems are often dispersed by the composition of the subsystems; and the various sub-systems are often used by different manufacturers of equipment and programs. User needs, these subsystems will be integrated and unified framework for real-time monitoring system.
2, such as real-time monitoring system needs to solve the scattered data sharing subsystem, the subsystem needs a unified command to coordinate the corresponding control.
3, taking into account the real-time monitoring systems are often need to upgrade and adjust.
4, the subsystem will need to open up with a unified interface.
5, OPC (OLE for Process Control) specification is a product of this thinking.
6, OPC based on Microsoft's Distributed interNet Application (DNA) architecture and the Component Object Model (COM) technology, according to the scalability and ease of design. OPC specification defines a standard interface industry.
7, OPC is based on OLE / COM application mechanism as a communication standard. OLE / COM is a client / server model, has nothing to do with language, and code reusability, ease of integration and so on. Standardized OPC interface function, regardless of the scene in which the form of equipment, customers have a unified approach to access, thus ensuring the transparency of the software to customers, and allows users entirely from the development of low-rise out of them.
8, OPC defines an open interface, this interface, the PC-based software components can exchange data. It is a Windows-based OLE - Object Linking and Embedding, COM - Component Object Model (Component Object Model) and DCOM - Distributed COM (Distributed COM) technology. Therefore, OPC automation layer for typical industrial applications to connect field devices and office procedures to provide an ideal approach.
