Explanation: OPC (OLE for Process Control) is a standard for industrial automation that allows different devices and systems from different vendors to connect and share data and control commands. OPC provides a common interface for communication among devices, regardless of the vendor or protocol. This allows for more flexibility and scalability in industrial automation systems and ensures secure communication among devices.
