PROFIBUS & PROFINET International (PI), Fieldbus Foundation (FF) and HART Communication Foundation (HCF) are currently working intensively on the development of an architecture for a WirelessHART gateway. The background to this is that although the process industry appreciates the benefits of wireless communication it is still not making sufficient use of it. WirelessHART uses a mesh network, i.e. each device can generate or receive signals (sensors/actuators) and pass them on to surrounding devices (repeater function). According to users the greatest obstacle when implementing wireless systems is the complicated integration of WirelessHART mesh networks into the existing automation environment.
