In the RCPI (rod control and position indication) system prototype of the TMSR (Thorium Molten Salt Reactor) project, EPICS (Experimental Physics and Industrial Control System) was adopted as instrumentation and control software platform. According to long time running, high availability and safety for the system, RMT (redundancy monitor task) software package for Input/Output Controller (IOC) redundancy was employed, and the driver for redundancy control was realized. Test shows that the system could achieve IOC redundancy switch-over quickly and ensure the IOC running with long-term stability.

Key words: Redundancy monitor task, EPICS, Thorium Molten Salt Reactor, Rod control and position indication
