PFEIFFER EVR116 Data Interface Channel

The PFEIFFER EVR116 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.

PFEIFFER EVR116 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);

PFEIFFER EVR116 defines the format of the transmission and exchange in the channel for the needs of process control.The architecture of the OPC standard is a client/server model, i.e. the software is divided into OPC servers and OPC clients.The OPC servers provide the necessary standard interfaces for accessing the OPC data; the OPC clients access the OPC data through the standard interfaces.
