PURPOSE:To train an operator in various kinds of operating modes and to improve reliability in driving operations of a plant by installing a plant model device to the outside of a control board of an actual plant. CONSTITUTION:A piece of information of a plant is connected to an outside plant model device 13 through a changeover circuit AX by each signal of monitoring and operation. This model device 13 can simulate various kinds of operating modes necessary for operation of the plant. For instance, in case when the changeover switch SW is operated and the auxiliary relay X is energized in an alarm circuit, contacts A1-An for the cause of faults are changed over to an input circuit SM1 of the plant model device SM by the changeover circuit AX. Further an input signal of an ANN arithmetic device is changed over to an output circuit SMO of plant model device SM in the same way. In this state, the contacts A1-An are fetched into the plant model device and the state of the plant is monitored automatically. |
