Openness, Productivity and Connectivity or Open Platform Communications (OPC) is mainly designed to provide a common communication bridge for Windows-based software applications and process control hardware. Specification of OPCs are based on the OLE, COM, and DCOM technologies
OLE stands for Object Linking and Embedding. It allows you to create objects with one application and then link them in a second application. OLE supports software applications like Microsoft Excel, Word and PowerPoint, Corel WordPerfect, Adobe Acrobat, AutoCAD etc.
This course is designed to help students to understand the basic Principles of OPC in detail.
After completion of this course, students will know about the latest development in OPC, OPC – overview & Data Access specification, Alarms & Events and Historical Data Access etc.
