What does OPC Server stand for?
Open Platform Communications
Today the acronym OPC stands for Open Platform Communications. These are just some of the reasons why so many members and other technology organizations (collaborations) are turning to OPC UA for their interoperability platform.
What is Softing OPC?

What is OPC UA protocol?
OPC Unified Architecture (OPC UA) is a machine-to-machine communication protocol used for industrial automation and developed by the OPC Foundation. The OPC UA platform in an platform-independent service-oriented architecture that integrates individual OPC Classic specifications into an extensible framework.
How does OPC server work?
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.
What is OPC UA server and client?
Like controlling devices in other technologies, an OPC UA Client device sends message packets to server devices and receives responses from its server devices. Beyond this basic functionality, an OPC UA Client device is fundamentally more sophisticated than controllers in other technologies.
How does an OPC server work?
OPC is a client/server technology. One application acts as the server providing data, and the other acts as a client using data. OPC is a widely accepted industrial communication standard that enables the exchange of data between multi-vendor devices and control applications without any proprietary restrictions.
What is the difference between OPC server and client?
Client/Server describes the relationship between two computer applications in which one application, the OPC client, makes a service request from another application, the OPC Server, which fulfills the request.
Why do we need OPC UA?
OPC UA is a standard that ensures the open connectivity, interoperability, security, and reliability of industrial automation devices and systems. OPC UA is widely recognized as the key communication and data modeling technology for the Industry 4.0 initiative.
What is the difference between OPC server and OPC client?
The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is any program that needs to connect to the hardware, such as an HMI . The OPC client uses the OPC server to get data from or send commands to the hardware.
What is OPC connectivity?
OPC is a software interface standard that allows Windows programs to communicate with industrial hardware devices. OPC is implemented in server/client pairs. The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol.
