PROBLEM TO BE SOLVED: To prevent an operation command from not being outputted to equipment only by touching a pointing device by mistake when plant control is performed by operating the pointing device. SOLUTION: In the plant control equipment which inputs plant operation commands by using the pointing device 3, the operation of the pointing device 3 for switching a plant state monitoring screen displayed on a display device 3 to a screen for operation mode and the operation of the pointing device 3 when operation contents are selected by selecting equipment to be operated are made different. Consequently, such a state that both of the switching of the screen and the selection of the operation contents are unwillingly inputted by merely touching the pointing device, is eliminated. |
