OPC: The Standard Communication Bridge for Industrial Automation

In modern industrial environments, automation systems often comprise a wide range of equipment and software from different manufacturers. These include PLCs, DCS systems, flow meters, gas analyzers, SCADA systems, and HMI software—each with its own communication protocols and data formats. OPC (OLE for Process Control) was developed to address this fragmentation by providing a standardized, […]
