Overview
The WiHART2 WirelessHART compliant wireless module is designed for swift hardware and firmware integration in process automation field instruments or adapters. The WirelessHART standard (IEC62591) was architected for field instruments and infrastructure devices engaged in process automation and control. Centered on Silicon Labs’ MG24 SoC, it includes multiprotocol support for WirelessHART (IEEE 802.15.4) and Bluetooth Low Energy.
The communication stack and reference field instrument implementation are compliant to the latest HART 7.6 specification. The WiHART certifiable field instrument implementation includes all the components needed to develop and certify a WirelessHART (Fieldcomm) instrument, including all mandatory Universal, Common Practice and Wireless commands, a HART modem and FSK maintenance port. It also includes sensor and peripheral driver as well as a power optimization engine.
The WiHART2 wireless module is also offered in WirelessHART/ISA100 dual-boot mode.
High data communication reliability is ensured through frequency hopping, time diversity and path redundancy (mesh) which are an integral part of the standard. It is highly secure being based on a two-layered security construct that includes AES-128 encryption as well as advanced authentication schemes.
