4. © ABB University - 4 Revision C OPC Standard OPC Communication 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

6. © ABB University - 6 Revision C Basic Rules OPC Communication 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.
