Abstract
Abstract A personal computer or equivalent is programmed to create a virtual operating unit for a robotic device (eg., a micro-processor controlled machine, conveyor, etc.). The actual operating unit, which plugs into the robotic device and controls it, includes a keypad and a display. When reprogramming the machine, the operating unit is unplugged and the computer is plugged in. The computer can be switched between two modes. In a programming mode, the computer is used to modify the program in the robotic device microprocessor. In an operating mode, the computer mimics the operating unit to test the newly-entered program. On the computer screen are generated a virtual display (the image of the actual display of the operating unit) and a map of the operating unit keypad. The technician observes the virtual display on the computer screen and enters commands, indirectly, through the computer's keyboard instead of through the actual operating unit keypad. The virtual operating unit allows the robotic device program to be tested without disconnecting the personal computer and re-connecting the actual operating unit. The virtual keys may be highlighted, as by flashing, when the corresponding keys of the computer keyboard are touched.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A system for programming and operating a stored program control device for a machine, the system comprising: a non-programmable operating unit having connection means for connecting with the control device for operating the control device, the operating unit including keys in a keypad arrangement; a programming unit adapted to be connected with the control device when the operating unit is not operatively connected with the control device, the programming unit functioning selectively in a programming mode and an operating mode wherein the programming unit mimics the operating unit; a keyboard coupled to the programming unit; a visual screen coupled to the programming unit; program switching means for switching between the programming mode and the operating mode; the programming unit including, in the programming mode, means for programming the control device; the programming unit including, in the operating mode, means for displaying on the screen a keypad image representing the keys in the keypad arrangement; and the keyboard selectively activating the control device according to the keypad arrangement.
Claim 2
Independent Claim
167 words
A system for programming and operating a stored program control device for a machine, the system comprising: a non-programmable operating unit having connection means for connecting with the control device for operating the control device, the operating unit including keys in a keypad arrangement; a programming unit adapted to be connected with the control device when the operating unit is not operatively connected with the control device, the programming unit functioning selectively in a programming mode and an operating mode wherein the programming unit mimics the operating unit; a keyboard coupled to the programming unit; a visual screen coupled to the programming unit; program switching means for switching between the programming mode and the operating mode; the programming unit including, in the programming mode, means for programming the control device; the programming unit including, in the operating mode, means for displaying on the screen a keypad image representing the keys in the keypad arrangement; and the keyboard selectively activating the control device according to the keypad arrangement.
Claim 3
Dependent Claim
45 words
The system according to claim 1, wherein: the operating unit further includes a first operating unit display; and wherein the programming unit further includes, in the operating mode, means for displaying on the screen a second display image corresponding to the first operating unit display.
Claim 4
Dependent Claim
35 words
The system according to claim 1, wherein the programming unit further includes, in the operating mode, picture means for creating on the screen an operating unit image corresponding to an appearance of the operating unit.
Claim 5
Dependent Claim
14 words
The system according to claim 1, wherein the programming unit is a personal computer.
Claim 6
Dependent Claim
57 words
The system according to claim 1, wherein the operating unit is connectable with the control device by a plug connection; the programming unit is adapted to be connected with the control device by the same plug connection; and the plug connection is adapted to connect the control device selectively to the operating unit and the programming unit.
Claim 7
Dependent Claim
14 words
The system according to claim 5, wherein the plug connection is a serial interface.
Claim 8
Dependent Claim
14 words
The system according to claim 5, wherein the plug connection is a parallel interface.
Claim 9
Dependent Claim
19 words
The system according to claim 1, wherein the switching means further comprises program switching means operable by the keyboard.
Claim 10
Dependent Claim
33 words
The system according to claim 1, further comprising means for highlighting a virtual key of the keypad image representing the keys in the keypad arrangement, the means for highlighting responsive to keyboard actuation.
