Simple. Reliable. Secure.

The HART Communication Protocol has served as the world’s leading process communication technology for smart instruments since 1989. Today, with approximately 30 million HART devices installed and in service worldwide, HART technology is the most widely used field communication protocol for intelligent process instrumentation. With the additional capability of wireless communication, the legacy of benefits this powerful technology provides continues to deliver the operational insight users need to remain competitive. More HART products are installed in more plants around the world than any other communication protocol.WirelessHART

Benefits of HART Communication:
- Fast & easy device commissioning & loop troubleshooting
- Remote access to all device information & diagnostics
- Streamline maintenance procedures
- Enables predictive maintenance
- Increases plant availability
- Low cost access to stranded process information
- Large selection of devices that work together
- Industry standards reduce overall costs

WirelessHART technology is a complementary enhancement to the HART Protocol, providing an additional capability that can benefit both existing and new monitoring and control applications. It is a robust technology that is simple to implement. It enables users to quickly and easily gain the benefits of wireless technology while maintaining compatibility with existing HART devices, tools and systems. Wireless HART is the Simple, Reliable, and Secure way to address your process monitoring, control, and asset management applications.   WirelessHART Brochure

Field Network Solutions (WiHART) - See your Plant in a Whole New Way
Wireless Field Networks have specific requirements which are different from those of a Plant Network. Field Networks are focused on process applications like measurement or sensing, process control and diagnostics.

Wireless Network SolutionsRequirements include:
- Process Applications – sensing, condition monitoring, control and diagnostics
- Bandwidth – Short, high priority communications
- Security/Reliability – must coexist and perform in dynamic, harsh plant environment
- Power Management – Intrinsically safe power solutions optimized for user & process safety lasting at least 5 years
- Standards – IEC-approved WirelessHART (802.15.4) is driven by Process community

Devices based on IEC 62591 (WirelessHART) technology use small amounts of bandwidth enabling high priority communications. Security and reliability are very important for these solutions as well and have been engineered into the WirelessHART standard utilizing proven industry standards. However, one of the most important requirements that characterize field networks is the extremely low power requirement. Emerson has invested in SmartPower innovations enabling extremely power efficient devices with unequaled safety and ease of use. These devices are powered by an intrinsically safe Power Module that lasts for 5 to 10 years. These SmartPower enabled devices use 10 times less power that other wireless networking solutions that consider themselves “low power”.

Wireless Plant Networks (Wi-Fi)
Wireless plant networks have requirements that are unique and different from wireless field networks. Plant networks implement applications like video, voice and people or asset tracking.

Wireless Plant NetworkRequirements include:
- Bandwidth – High; multiple applications must share the service
- Security/Reliability – Industrial security and robust coexistence are essential
- Power Management – Devices can be line powered or recharged daily
- Standards – Driven by IT community (802.11, WIMAX, LTE...)

Emerson has been delivering wireless products and solutions at the plant network level since 2001, when IEEE 802.11 became an accepted standard in the process industry. Our experience has demonstrated the importance and benefits of using WLAN technology in manufacturing and processing plants. Our Smart Wireless architecture uses rugged wireless access points from Cisco to provide Wi-Fi coverage. The Cisco Outdoor Wireless Mesh Access Points are Class I, Div 2 (ATEX Zone 2) certified and support dual band radios compliant with IEEE 802.11 a/b/g/n standards, providing a universal standard network infrastructure for easy integration of all the wireless applications in your plant, including security, personnel and asset tracking, and mobile worker productivity solutions.  Smart Wireless Solutions Brochure
