Description
REC650 1MRK008514-CB Data Interface Channel
REC650 1MRK008514-CB establishes a set of communication interface specifications that meet the requirements of industrial control, so that the control software can efficiently and stably access the data of the hardware device, and the application software can flexibly interact with each other, which greatly improves the interoperability and adaptability of the control system.
REC650 1MRK008514-CB From the software point of view, OPC can be regarded as a “software bus” standard. Firstly, it provides a channel standard for real-time data transfer between different applications (even between applications on different workstations connected via a network);
REC650 1MRK008514-CB defines the format of the transmission and exchange in the channel for the needs of process control.The architecture of the OPC standard is based on a client/server model, i.e. the software is divided into an OPC server and an OPC client.The OPC server provides the necessary standard interfaces for accessing the OPC data; the OPC client accesses the OPC data through the standard interfaces.
