OPC UA
OPC Unified Architecture (OPC_UA) is a machine-to-machine communication protocol for industrial automation developed by the OPC Foundation. OPC_UA enables secure and reliable data exchange between industrial devices and systems. These systems include programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, and human-machine interfaces (HMIs).
