Cirronet puts the power of ZigBee into industrial wireless networks

SAN FRANSISCO, March 2, 2005 — It’s the age-old question. How can companies integrate the latest and greatest technology into existing networks without spending a bundle and tying up the engineering team? Cirronetà¢â€ž- has answered that question for incorporating ZigBee wireless technology easily and inexpensively into existing industrial automation networks.

Cirronet, Inc., a provider of wireless OEM modules and industrial standalone products, is demonstrating its ZigBee ModBus Gateway and ZigBee Sensor Modem for industrial automation today at the ZigBee Alliance Open House at the Sir Francis Drake Hotel in San Francisco from 10 a.m. until 7 p.m.

“Before now, no one has had the pieces needed to add the benefits of ZigBee technology easily to an existing network,” said Tim Cutler, vice president of sales and marketing. “What Cirronet offers is an off-the-shelf solution that enables companies to add ZigBee technology to their industrial automation systems without the cost and time of making changes to their network.”

Specifically, Cirronet’s products allow PLCs from a variety of vendors to communicate with remote sensors and actuators over a ZigBee network using standard ModBus addresses and commands. Since the ZigBee ModBus gateway communicates with the PLC using the ModBus protocol, existing monitoring programs can still be used to report on ZigBee connected devices.

Companies are increasingly using wireless sensors and networks to monitor factory floor conditions and control automated systems. Wirelessly networked monitoring and control products based on the ZigBee standard create easily deployed, redundant path, low-cost systems for integrating even the simplest sensors into industrial automation systems.

In its June 2004 Industrial Wireless Sensor Networking report, research firm On World projected that deployed industrial wireless sensor network nodes will increase from 330,000 in 2004 to 85.9 million in 2010, representing end-user revenues of $2.9 billion. In 2010, ZigBee nodes are projected to comprise 85% of the total, or 72.6 million.

Samples of Cirronet’s ZigBee OEM modules will be available at the end of March. Standalone products like the ZigBee ModBus Gateway and ZigBee Sensor Modem demonstrated today will be available from Cirronet in the second quarter of 2005.
