PURPOSE:To use the digital display device of an electric power plant by displaying a process value on the dedicated display device when it is important for plant conditions, and selectively displaying the process variable when it is not important. CONSTITUTION:Process variables detected by detectors 1'-1'n are inputted to an electronic computer 5. An important process variable detected by a detector 1, on the other hand, is inputted to a detection part 2, where it is converted into a binary code. The obtained code data is inputted to a display control part 3 by being selected by a gate part 6. This gate part 6 performs switching between process data of a computer 5 and the process data from the detection part 2 in accordance with a switching signal 7 from the computer 5. When a turbine is started, its rotational frequency is an important process variable, which is read in the detection part 2 through the detector 1 and displayed on a display part 4, but when the turbine starting is completed, it is used as a rated speed, so that the gate part 6 is changed over to the side of the computer 5 by the signal 7. |
