Abstract
In order to solve the problem that signal jump of DCS controller in the process of incremental downloading and after switching of host⁃slave controllers,an in⁃depth research was made for the hot standby redundancy,incremental downloading, host⁃slave switching mechanism and logic configuration within DCS. The study show that the irregular logic configuration under DCS controller incremental downloading mechanism made the controller unable to keep the state of part signals after host⁃slave switching. After a thorough investigation and resolution,the signal jump risk of the DCS controller was eliminated.关键词
