Abstract
The STAR (Solenoidal Tracker At RHIC) experiment located at Brookhaven National Laboratory has been studying relativistic heavy ion collisions since it began operation in the summer of 2000. An EPICS-based hardware controls system monitors the detector's 40000 operating parameters. The system initially used VME processors to communicate with sub-system based sensors over a variety of field busses. The system is being revised transferring user displays from Sun Workstations to PC's and replacing aging VME processors with PC's. The first subsystems were replaced during the Spring and Summer of 2006. The new hardware has been implemented in a way that it can operate in parallel with the existing hardware and software.
