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. |
