Emerson Process Management is licensing royalty-free patent rights for its
PIDPlus wireless PID controller technology to improve real-time control performance,
simplify tuning, and inherently protect against system failures across all control
systems. The licenses will be provided through the HART Communication Foundation,
the independent organisation that provides global support for the application of
HART technology.
A WirelessHART measurement and actuator device featuring a digital control
system (DCS), PIDPlus can be custom created on most existing automation systems
and has been a standard feature of Emerson’s DeltaV distributed control system (DCS)
for more than four years. Within the DeltaV system, PIDPlus enables effective and
reliable control using WirelessHART communication optimised for improved battery
life.
HART Communication Foundation President Ted Masters describes the offer
of PIDPlus technology to their broader membership as another step to advance the
capability of WirelessHART towards reliable real-time control. He explains that
contributions such as these from member companies continue to push HART Communication
Protocol to cutting edge technology to the benefit of the entire process automation
industry.
Peter Zornio, chief strategic officer, Emerson Process Management adds
that WirelessHART has undergone rapid adoption across a variety of industries,
with the technology providing users greater confidence and performance when using
wireless for more critical applications.
