Abstract
PURPOSE: To avoid stopping the plant even with unexpected failure in the computer electric circuit, by sufficiently using the function of computer and making easy and suitable the grasp of operator information and analysis of arrangement, through the sufficient use of computer function.
CONSTITUTION: The function of the computer 2 is sufficiently used, and the operation index value PVg of the process 1 and the operation measurement value PVm are displayed to the time axis on the display unit 3. Further, at non-steady state, the operator can operate the set section 4 to avoid the deviation while observing the display and at steady state, the operation actual measurement value PVm performs coefficient adjustment with the computer 2 so that the deviation can be avoided along the normal operation index value PVgc. Thus, the start up, grade selection and shut down can suitably be made, the judgement of operation state is made easy. Since the set signal Is is always kept even if the computer 2 is in failure at normal operation, the operation can safely be continued without dangerous process 1.
