PROBLEM TO BE SOLVED: To execute a fault simulation through easy operation. SOLUTION: An initializing means 2 of the digital controller 1 initializes a device. A process input means 3 inputs plant data from a plant 100. A scheduler means 4 performs control operation for the plant data according to a control program. A process output means 5 outputs data to the plant. A mode switching means 6 switches a normal mode to a simulation mode at a request from a maintenance tool. A fault simulating means 10 performs fault simulation in the simulation mode. |
