OPC Connections
Connect OPC servers and clients, and integrate their data
OPC is a widely-used protocol for connecting industrial hardware and devices with HMIs and other software. An open standard, OPC supports communications for thousands of diverse products, keeping costs down for plant owners and hardware suppliers alike.
OPC Classic, implemented in the 1990s, includes OPC Data Access (OPC DA) and OPC Alarms and Events (OPC A&E) and has a broad, well-established user base. Most OPC implementations in the world are OPC DA. OPC UA, which includes Alarms and Conditions (OPC UA A&C), was introduced several years ago to expand the domain of OPC beyond traditional industrial applications, and to provide improved networking and security.
