A new system is being developed to control the power supplies for the electronics of the time projection chamber at the STAR (Solenoidal Tracker at RHIC) experiment. A PLC (Programmable Logic Controller) will replace a twelve year old VME-based system. The new power supply controls will be more compact and operate on processors which have higher reliability and greater computing speed. The system has been tested using TwinCat, a software package provided by the hardware manufacturer, Beckhoff. This software is being integrated into EPICS (Experimental Physics and Industrial Control System), the current STAR control system.
