Archiving CompactRIO Process Data to PI

The tool we most commonly use for real-time embedded process monitoring and control applications is the NI CompactRIO. These controllers allow us to embed algorithms that acquire and analyze high-speed process sensor data and then output derived key performance indicators (KPIs) to other control systems. Most of the time, our customers also require us to send the KPIs to a real-time data infrastructure like OSIsoft’s PI System so plant managers and engineers can use the data to find energy savings, monitor asset health, or optimize processes.

For our latest CompactRIO systems we have developed APIs that allow us to send or receive data directly to and from PI. We utilize the PI Asset Framework and the UFL Connector to automatically generate PI tags from the device and update the process tag values either on value change or on a time basis.

These tools greatly simplify our CompactRIO-to-PI System communication process by eliminating intermediary data servers and automatically generating PI tags based on a CompactRIO system’s configuration.
