Beckhoff Automation offers its OPC UA in TwinCAT software—one of the first to implement the new OPC UA specification, company says.
OPC is an established and recognized standard for data exchange between control and HMI in manufacturing and process automation. Previous OPC technology was based on the Microsoft COM/DCOM model and was limited to a Microsoft-based operating system. The new OPC UA standard is based on TCP communication and is, therefore, platform-independent. A “Unified Architecture” specification creates the basis for new platform-independent communication and information technologies. In addition to standardized exchange of PLC process data, the OPC UA solution offers device-specific information and services.
