Claims
- 1. A distributed control system for performing functions at a plurality of physically separated function points, conprising:
- (a) at each function point:
- (i) actuating means for carrying out a specific function; and
- (ii) function control means for controlling said actuating means, said function control means including a programmable microprocessor having an associated memory and interface, said microprocessor being configurable to provide a selected control function for controlling one of a plurality of different types of actuating means;
- (b) at least one of said function points comprising:
- (i) a sensor connected to said actuating means and to an input of said function control means, and forming a continuous feedback loop;
- (c) a common computer connected to the function control means of each function point through a first common connection loop, said computer comprising:
- (i) means for transmitting, during a start up phase, a first set of digital signals for configuring the function control means of each function point to provide a selected control function; and
- (ii) means for transmitting to the function control means of each function point, during an operating phase, a second set of digital signals comprising operating commands for the specific function to be carried out by the actuating means controlled by said function control means; and
- (d) means for supplying energy to said actuating means through a second common connection loop.
- 2. The system of claim 1, wherein at least one function point comprises:
- means for providing information to the associated function control means, and the associated function control means comprises means for continuously transmitting said information to said common computor under the control of said second digital signals.
- 3. The system of claim 2, wherein said means for providing information provides information in the form of electrical impulses.
- 4. The system of claim 1 or 2, wherein the common computer comprises means for providing, during the operating phase, at least one switching phase comprising digital signals for configuring the function control means of at least one function point to provide a new control function.
- 5. The system of claim 1, wherein the functions of the system comprise at least the function of an industrial robot with a multi-articulated arm which performs a large number of linear and polar movement and having on a free end a means for the processing of articles.
- 6. The system of claim 5, wherein the system includes a low pressure chamber containing said robot; at least one means for supplying a material; and said arm comprising at least one means for applying said material.
- 7. The system of claims 5 or 6, wherein the robot is coordinated in the system with a sparately positioned one of said actuating means comprising at least one pump for the supply of working material of an industrial process.
- 8. The system of claims 5 of 6, wherein the system includes manually operated program teaching means for permitting the use of the common computer for the reduction of redundant degrees of freedom in the movements of the articulated arm.
- 9. The system of claim 1, wherein the function control means of each function point comprises means for determining the sequence of the function control means in said first common connection loop.
- 10. The system of claim 1, wherein the number of wires in said first common connection loop is less than twelve, or said first common connection loop comprises wires having a cross-sectional area of less than approximately three hundred square millimeters.
- 11. The system of claim 1, wherein the function control means connected to said first common connection loop
