A control system for a turbomachine such as a steam turbine includes an integrated control and display system (32,34) with means for automatically reconfiguring itself for each phase of operation. In each phase, only those displays and controls (60,62,64,66) required during that phase are provided; all other controls and displays are omitted. In one embodiment, inputs from the turbomachine pass through a decision tree for uniquely determining the phase of operation. The output of the decision tree selects and display and control parameters from a screen library. The screen library controls and positions of indicia and indicators on the displays and controls. The indicated values are determined from measured parameters. In one embodiment, a touch screen is employed for executing controls.; The X and Y values of touch-sensitive parts of the screen are interpreted in terms of the intended control functions for the particular existing phase of operation.
