Selected Answer: B
OPC, Open Platform Communications. A long time ago you may have known OPC as Object Linking and Embedding for Process Control. OLE. It was developed back in 1996 by an industrial automation industry task force. There's this continuous quest to find that universal protocol that's going to work with everything and anything, and to improve things. The original OPC is based on Microsoft COM and DCOM, object link embedding, component object models, distributed component object model technology, the communications within the Microsoft OS operating system. It specifies the communication of real-time plant data between control devices from different manufacturers. IC32M page 352
