Abstract
PURPOSE:To prevent the expansion of a trouble caused by a judging mistake of an operator and also avoid the discontinuation of the plant operation, etc., displaying the faulty equipment and the trouble affecting range in case one of those component equipments of a plant. CONSTITUTION:An operation state deciding part 101 connected to a plate A via measurement signal lines B is used together with a state display deciding part 102 connected to the part 101 via a signal line, and a display screen 103 connected to the part 102 via a signal line. The part 102 contains a memory which stores a block line diagram showing the degrees of connections among equipments, i.e., the degrees of influence given to the subsequent equipments in case a specific equipment has a trouble. Thus an affecting range of the trouble is decided from the trouble signal and the block line diagram stored in the memory. As a result, the expansion of the trouble caused by a judging mistake of an operator can be avoided together with no discontinuation of the plant operations.
