Invensys’ Eurotherm nanodac links easily to enterprise-level systems while providing powerful control and data recording functions. Invensys Operations Management, a global provider of technology systems, software solutions, and consulting services, has introduced the latest version of its Eurotherm nanodac recorder/controller, including three important updates that link the device more closely with the company’s InFusion Enterprise Control System. The updates include greater storage flexibility for longer local data archiving, store and forward data retrieval, and connectivity to a Wonderware historian.

The nanodac recorder/controller can serve as a local historian to third-party equipment, but can also be utilized as a stand-alone device. It interfaces directly with the Wonderware historian, providing a unique combination of secure, hardware-based local data acquisition and storage, along with powerful information, analysis, and reporting software. With 50 MB of flash memory for data storage, as well as an on-screen help system and remote viewing functionality, the device allows plant-floor operators and supervisors to monitor and discuss the health of their process from virtually anywhere.

“High-integrity data collection and retention for continuous or batch processing is critical for many industries,” said Bob Postlethwaite, global marketing director, Invensys Operations Management. “Without a local collection and retention device, when communications fail, processors risk losing important data. For a food and beverage or pharmaceutical manufacturer, for example, that could lead to a batch being quarantined or even scrapped. With its local historian and powerful memory, the Eurotherm nanodac recorder/controller can store up to 38 set-up values. Additionally, its ‘store and forward’ connection to our Wonderware historian component not only ensures that data retrieval is automatically implemented whenever needed, it is restored in crystal sharp display with highly accurate records that are updated eight times every second.”

In addition to its extensive data acquisition capability, the Eurotherm nanodac instrument also has an option to provide two high-stability PID loops with a proprietary auto-tuning feature. Both the product and its remote viewer application support several languages, including English, French, German, Italian, and Spanish. The device also:

• Meets many exacting standards for measurement, including Nadcap for aerospace compliance
• Can be used to aid 21CFR Part11 compliance for pharmaceutical electronic records
• Has up to eight universal inputs coupled with high-density recording, and
• Produces tamperproof files that can be retained in a long-term archive.

Postlethwaite added, “Incrementally upgrading your operations with InFusion Enterprise Control System hardware and software components can be a strategic, economical modernization effort that links business processes with production processes. It allows our customers to create the solutions they need to improve collaboration and to make the most of their most valuable asset—their people.”
