A drilling system includes machines, process sensors, and a drilling ECU. Each machine has machine sensor which senses an operating state and an operating range with a lower and upper limit. Each process sensor has a process sensor value and a process range with a lower and upper limit. The drilling ECU includes a data processing apparatus and a memory. The memory includes a process model with expected values of the process sensors as a function of a drilling depth, and a reservoir model with geological data. The drilling ECU receives the process sensor value and the operating state, calculates first differences between the process sensor values and the upper limit and/or the lower limit of the process range, calculates second differences between the operating state and the upper limit and/or lower limit of the operating range, and displays the first and second differences on a drilling screen.
