OPC Server Can Accelerate the Communication between Windows Program and Industrial Hardware

       OPC is a software interface standard that allows Windows programs to communicate with industrial hardware devices. It 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. 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.

       The value of OPC is that it is an open standard, which means lower costs for manufacturers and more options for users. Hardware manufacturers need only provide a single OPC server for their devices to communicate with any OPC client. On the other hand, users can choose any OPC client software they need, resting assured that it will communicate seamlessly with their OPC-enabled hardware, and vice-versa.

       Based on Microsoft Windows technology, OPC now stands for Open Process Control. Previously it stood for OLE Process Control but today the OLE technology has been replaced by Active X. OPC is an industry standard created with the collaboration of a number of leading worldwide automation hardware and software suppliers, working in cooperation with Microsoft. The standard defines methods for exchanging realtime automation data between PC-based clients using Microsoft operating systems. The organization that manages this standard is the OPC Foundation.
