OLE for Process Control Training


In the early stages of automation processing, most SCADA/ and historian manufacturers had drivers running directly in their client applications. Although most of these drivers were for their own hardware set, some common protocols were occasionally included (like Modbus).

The problem that end users encountered was that one manufacturer’s client software often could not communicate with another manufacturer’s hardware or PLC/DCS. This meant that end users were limited to the product offerings from a single hardware manufacturer. It also limited the potential market forAutomation suppliers, who faced challenges selling their hardware to plants that, had specialized in a different brand.

This course provides overall OPC knowledge. All major aspects of OPC are covered by classroom presentations and laboratory exercises.


Students completing these courses receive a good grounding in OPC principles and strategies, diagnostics, and troubleshooting OPC.
