Abstract
A remote control terminal for a printing machine has a single central display for indicating all machine functions and accepting operator input of all the control information and which is easily used by a machine operator of ordinary skill. The control terminal has a transparent matrix switch and a machine diagram template overlayed on a color monitor under computer control. Control of the printing machine is a hierarchal process starting from the selection of a machine status area indicated on the machine diagram. Fault signals, however, are indicated directly and automatically for immediate operator attention. Selected correction possibilities are offered so that the operator does not need to investigate the possible location or cause of the defect. Machine functions and subsystems are color coded on the machine diagram. Similarly, machine data is color coded to distinguish input areas, set points, measured values, adjustments, and legends and messages. Thus, it is not necessary for the machine operator to observe all of the machine parameters, and instructions or inputs cannot be fed unchecked or accidentally to the control system.
