3. A method for control, diagnostics, and maintenance of factory systems and processes utilizing process/machine controllers, a communication satellite system, and at least one self-contained portable computing unit, comprising the steps of:
-
generating an alarm signal when a machine/process goes out of a specified parameter range; communicating the alarm signal to a satellite system; relaying the alarm system from the satellite system to at least one self-contained portable computing unit; displaying on the computing unit a location, on the factory floor, of the alarm signal; further displaying on the computing unit the machine/process originating the alarm signal; and displaying on the computing unit information for correcting the cause of the alarm signal. - View Dependent Claims (4, 5, 6)
