But these are all transparent to OPC client programs, and they only need to follow the same specifications or methods to read data from the server. Similarly, software suppliers only need to add OPC interfaces to their software to obtain data from OPC servers without worrying about underlying details

Through the OPC interface, OPC client programs can connect to one or more different OPC servers. At the same time, an OPC server can also be connected to multiple client programs, forming a many to many relationship

Any product that supports OPC can achieve seamless integration with the system. Due to the fact that OPC technology is based on DCOM, client programs and servers can be distributed on different hosts, forming a networked monitoring system.

The development and application of OPC technology can benefit both suppliers and end users greatly. Firstly, OPC technology effectively separates hardware and application software. Hardware manufacturers only need to provide a set of software components

which can be used by all OPC client programs without the need to repeatedly develop driver programs. Once the hardware is upgraded, only the OPC server side I/O interface needs to be modified without modifying the client program
