Emerson introduced the most recent evolution of the Ovation compact controller and a new playback recorder for plant operational data during WEFTEC in Chicago.

The compact controller (Model OCC100) product line is a non-redundant controller with a small footprint designed for the water and wastewater industry. A suite of communication protocol software and wide-area networking technology reside in the controller, reducing complexity and giving small- and mid-sized municipalities a cost-effective way to boost reliability and control geographically dispersed equipment.

It is well-suited for applications where redundancy may not be needed. Examples include reservoir monitoring, gravity filtering, disinfection, tertiary treatment and pump or booster station operation. Besides operating independently, the controller can be merged into a larger, Ovation distributed control system, enhancing visibility into plant-wide operations.

The Ovation playback recorder automatically and continuously records operational data at the same resolution as the live control system. Like a digital video recorder, it has standard functions such as play, pause, fast-forward and rewind. With the ability to visually step through logic sequences using process graphics and signal diagrams, users can view historical data through the lens of what the operator would have seen under actual plant conditions.

This holistic and repeatable view of plant events can be used to speed troubleshooting, enhance training and support decision-making. Plant personnel can review actions taken during an abnormal event, such as a chemical spill or wet-weather event, to identify best mitigation responses. They can then update operating procedures to better manage similar events in the future. The recorder lets them quickly diagnose problems, minimize equipment damage and reduce maintenance.
