Better Manage Your Business, Your Plant

ENTERPRISE-WIDE PLANT ASSET INFORMATION DRIVES DECISION-MAKING
Capturing powerful, real-time predictive diagnostics in a secure web browser gives a comprehensive view of asset health. Wireless devices bring visibility to even more assets, enabling fast, accurate decisions to impact your plant’s bottom-line results.

By teaming with Cisco, Emerson provides a plant-level, wireless mesh network that is open-standards-based as well as scaleable, manageable and secure—all with a low total cost of ownership.

Your Most Important Assets

One especially powerful application enabled by a plant-level wireless network is for locating employees and visitors.

“Wireless technologies can now help you track everything in a plant, but the most important assets in any plant are its people,” says Karschnia. “A plant now can have a real-time people location system to locate all employees and visitors during emergencies.”

For example, wireless sensors can be mounted on safety showers. “Field network wireless technologies allow customers to cost-effectively install wireless flow switches on all safety showers,” Karschnia says. “This saves them thousands of dollars in wiring costs. These flow switches are integrated in the control system and the people location system.”

With this new wireless technology, Karschnia points out, “A plant can meet OSHA requirements for initiating an alarm five seconds to 10 seconds after a safety shower is activated. Hard-wiring every plant safety shower or eye-wash station back to the main plant annunciator system is simply cost-prohibitive.”

Because of the plant-wide wireless network, an operator can see the location of every employee’s RFID-enabled identification card. “We can then use the wireless location system to see who the closest first responder to that location is,” Karschnia says.

Voice, Video Boost Safety, Security

Many plants already are using wireless technologies to improve security. Wireless closed-circuit television cameras and RFID-equipped access badges enable intelligent security monitoring and control from restricting access to specific areas based on levels of security to tracking attempts to violate security protocols and helping security managers identify potential vulnerabilities and improve systems. Wireless applications also enable you to monitor hazardous applications in order to reduce risk to plant personnel. High-bandwidth video surveillance systems can use Cisco wireless mesh Wi-Fi networks to move data from the fence lines and other remote plant locations into the control room. This allows plant operators to have real-time video feeds from nearly every location in the plant. And this, in turn, permits operators to be more productive by making some types of operator rounds unnecessary. Operators can decide whether to take their wireless communication tools out into the plant after they know where they need to go, because they have already seen a problem or situation on a video feed.

AN INTEGRATED APPROACH TO FIELD AND PLANT WIRELESS
Emerson Process Management’s Smart Wireless solutions operate on an integrated, architecture of WirelessHART for field-level wireless communication and Wi-Fi for plant-level applications.

High-bandwidth video is also helpful when used in combination with RFID-based personnel monitoring. Personnel safety is greatly enhanced when the responders know right from the beginning of the incident whether the “person down” is in a dangerous situation, and when two-way communications are enabled via VoIP portable communications devices, responders can coordinate their actions and maintain a high degree of safety at the same time.

Peter Zornio, Emerson Process Management chief strategic officer, summarizes the disruptive, game-changing potential of today’s wireless technology as “measuring the immeasurable”—including inaccessible process readings, people and asset locations and security data. Further, wireless presents the opportunity to extend Emerson’s PlantWeb architecture and predictive technologies to places where they were previously cost prohibitive— including unmonitored valves, rotating equipment, vessel and pipe health, and stranded smart devices, he says.

“It’s as immediately straightforward as a more cost-effective alternative to wired for newly mandated environmental and safety applications—and as potentially game-changing in the future as to enable applications we don’t even know about yet,” Zornio adds. “It’s all the information on the move, anywhere.”
