How does OPC work with PLC?

The OPC server is a program that translates the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is a program that connects to the hardware, such as an HMI. The OPC client communicates with the OPC server to receive data or send commands to the hardware. A. P.

How does OPC protocol work?

OPC is a client/server technology. One application acts as the server providing data, and the other acts as a client using data.

What is the OPC standard?

• The OPC standard is a series of specifications developed by industry vendors, end-users and software developers. These specifications define the interface between Clients and Servers, as well as Servers and Servers, including access to real-time data, monitoring of alarms and events, access to historical data and other applications.

What is the OPC UA communication stack?

• This communication stack reflects the beginning of various innovations. The OPC UA architecture is a service-oriented architecture (SOA) and is based on different logical levels. OPC Base Services are abstract method descriptions, which are protocol independent and provide the basis for OPC UA functionality.
