WirelessHART Interface Links RTUs

The demand for oil and gas is leading producers to apply new methods of extracting hydrocarbon liquids. To facilitate this industry trend, Emerson Process Management has released an IEC62591-compliant WirelessHART interface for use with its remote terminal units (RTUs).
The native interface saves commissioning and startup time since no external gateways, Modbus or data mapping are required.

This native interface integrates Smart Wireless networks with Emerson’s family of remote terminal units and flow computers including ROC800, FloBoss, and ControlWave RTUs. With the interface installed, the RTU auto-detects the WirelessHART devices by sensing them as they are on or added to the network. This means that no site survey required, making it easy and fast to set up the wireless field instrumentation — saving time and money.

Wireless field devices on the Smart Wireless mesh network can automatically find alternate communications paths, thereby avoiding networking obstacles during setup. Network encryption, authentication, verification, anti-jamming and key management methods to ensure secure data transmissions. In addition, IEC62591 mesh communications yields greater than 99 percent communications reliability.

The native interface saves commissioning and startup time since no external gateways, Modbus or data mapping are required. The interfaces have I/O communication modules for RTUs and a Smart Wireless field link to provide a weather-proof, explosion-proof wireless interface for outdoor mast mounting. This installation allows physical and environmental mounting flexibility so that users are not limited to a specific location during device setup.
