Abstract

PURPOSE: To back manual operation up by setting corresponding relays by a control part by generating relay numbers for manual operation blocks from input information and then by automatically performing operation guide operation after prescribed time when improper operation is carried out.
CONSTITUTION: Various information I1 on a plant is processed by operation guide generator 20 to generate operation guide information I2, which is inputted to operation guide display unit 30 and displayed there. On the basis of memory information in memory part 43 in manual operation backup device 40, signal conversion part 41 generates from input information I3 a manual operation block relay number and its operation direction, and an automatic operation timer number and its set time and operation direction, and control part 43 receives them to set a corresponding relay or timer. Consequently, malfunction of an operator is prevented and if improper operation would be carried out, operation guidance is automatically attained after prescribed time, so that the manual operation backup of the operator can be done.
