  4. OPC Communication OPC Standard • OPC stands for OLE for Process Control. • OLE (Object Linking and Embedding) is a Microsoft technology for objects to interact with each other. • OLE is based on COM or DCOM. • While OLE was originally designed for office applications (e.g. Word, Excel). OPC technology is an extension of that protocol for industrial applications • OPC is a group defined protocol for process control data communication. • OPC Data Access for real time data • OPC Historical Data Access for historical data • OPC Alarm and Event for event data

  5. OPC Communication Structure and Data Flow Aspect Server Connectivity Server

  6. OPC Communication Basic Rules • The OPC Server must be installed in the same physical node as the Connectivity Server. • One OPC Server is allowed to subscribe to data from a maximum of 24 PM861 controllers, or the equivalent number of variables from other controller types. • A maximum of three OPC Servers are allowed to subscribe to Data Access and/or Alarm and Event from one controller. • Multiple OPC Clients can subscribe to data or event notifications from the same OPC Server. • A third-party OPC Client should, if possible, be installed on the same PC as the OPC Server.
