The design and implementation of configuration software and running software of redundancy in DCS are introduced,including hardware and software structure of redundancy system,parameter configuration,storage and downloading communication of redundancy information,automation switch control logic of running software,management of fault table,data exchange between running software and I/O modules.

The systems can be passivitized are extended by using logic switching, and on some conditions these discontinuous control laws that render the system passive can be smoothed.
