Invensys and Apprion Implement Managed Wireless Communications Infrastructure at PPG Lake Charles Chemical Complex

As part of an ongoing automation upgrade at the site, Invensys -- in conjunction with its strategic partner, Apprion -- has successfully completed the first phase of a comprehensive managed wireless infrastructure deployment at PPG Industries’ large chlor-alkali chemical manufacturing complex in Lake Charles, Louisiana. This infrastructure is designed to help further improve plant profitability, safety, and security, while providing a secure, flexible, and cost-effective foundation to support additional wireless applications in the future.

Invensys and Apprion implemented a common, layered network infrastructure following a comprehensive site assessment. The critical site assessment was conducted by a team that included Invensys, Apprion, and PPG personnel representing production operations, maintenance, safety, security and information technology functions. The new infrastructure incorporates multiple wireless technologies (both standard and proprietary), wireless devices, and wireless-enabled applications. Apprion’s IONosphere software platform provided the key enabling technology for security, policy and performance management of the entire wireless infrastructure. Wireless coverage, services, and applications for huge plants like PPG Lake Charles have been infeasible until recently Phase 1 wireless applications now in place at the site include: •

Wireless temperature condition monitoring •

Wireless site security monitoring (including remote video surveillance) •

Wireless environmental monitoring to help simplify regulatory compliance •

Secure wireless laptop and PDA access to provide authorized personnel with remote access to the site’s enterprise network "Wireless coverage, services, and applications for huge plants like PPG Lake Charles have been infeasible until recently," commented ARC Advisory Group Senior Analyst Harry Forbes. "This is clearly no longer the case. Now the challenge is to deploy and maintain a wireless infrastructure that can grow to support greater numbers and varieties of applications, and do so reliably and securely over a long period of time. It’s encouraging to see a wide variety of applications in this first phase of the project. I expect many more will be added as the ‘network effect’ begins to occur at plants like PPG and they realize the potential value of this new infrastructure." Introduced at the 2005 ISA EXPO in Chicago, Invensys’ unique managed network wireless strategy centers around shared access point technology and common data and security models for all wireless devices – regardless of vendor or application. As currently demonstrated at the PPG Lake Charles facility, Invensys’ comprehensive approach provides the freedom to select the wireless technologies that are best for any given application, while helping ensure appropriate levels of integration, robustness, and security for all industrial and enterprise wireless applications.
