After conducting an extensive multi-vendor field test, NAMUR reports that WirelessHART Communication provides the flexibility, security, robust performance, coexistence with other radio technologies and device interoperability within a WirelessHART network that its members should expect.

The NAMUR field test used WirelessHART products from ABB, Emerson Process Management, Endress+Hauser, MACTek, Pepperl+Fuchs, and Siemens to evaluate and verify WirelessHART compliance with NAMUR Recommendation NE124, "Requirements for Wireless Automation" and NAMUR Working Document NA115, “IT Security for Process Automation Systems”.

The field test conducted at the BASF facility in Ludwigshafen, Germany, included laboratory evaluation of performance characteristics and several implementations in operating process plant environments.
