WirelessHART was released in September 2007 and is the first open wireless communication standard specifically designed for real-time process control applications. It is designed to the same standards as its wired counterpart for reliability and interoperability. To ensure the compliance with the HARTTM Communication Protocol and the adherence to its strict timing requirements, all WirelessHART devices must be thoroughly tested and registered with the HART Communication Foundation (HCF). In this paper, the authors present Wi-HTest, the test suite designed to exercise WirelessHART devices, thus facilitating compliance assessment. They discuss the detailed architecture of Wi-HTest and highlight several critical features like packet handling with accurate timing control and fault data injection.
