PURPOSE:To prevent the rise of density of a display picture on a display device by selecting a selecting switch corresponding to the operation displayed on a display panel to operate a plant only at the time of selecting operation guidance information. CONSTITUTION:When a group selecting switch 5a (for the n-th group) of a process equipment 5 to be operated is depressed, pictures of the n-th group registered in the memory of a keyboard control part 5g are read out and are displayed on a display device 5f. When a device switch corresponding to an operation object in pictures displayed on the display device 5f is depressed, the depression position is inputted to the control part 5g by a touch screen 5e and the control part 5g displays an operation guidance corresponding to this position and the picture of a master operation switch from a control unit 4. Then, an operator depresses the master operation switch to operate the equipment 5. Thus, the rise of density of pictures displayed on the display device is prevented, and erroneous operations are prevented and the operability is improved. |
