Command and residual priority control of loads

A system for controlling a plurality of loads based upon command and residual priority comprising:

• a plurality of loads;
• control means for controlling said loads according to at least two programs, each program having a command priority used for a program which wants control of a load and a residual priority retained for the program having control, said control means comparing the command priority of the program wanting control of a load to the residual priority of the program having control for thereby providing a command instruction to the load if said command priority of the program wanting control is greater than or equal to the residual priority of the program having control;
• said control means storing the residual priority of the program wanting control if the command priority of the program wanting control is greater than or equal to the residual priority of the program having control;
• and,
• communication means connected between said control means and said loads for communicating the command instruction to said load.

A system for controlling a plurality of loads based upon command and residual priorities comprising:

• a plurality of loads;
• memory means having first memory locations for storing at least first and second programs, each program having a command priority used for a program which wants control of a load and a residual priority retained for the program having control, said memory means having second memory locations for storing a residual priority for each load based upon the program which is currently in control of the load;
• control means for controlling said loads according to said at least first and second programs, said control means comparing the command priority of a program wanting control of a load to the residual priority of the program having control for thereby providing a command instruction to the load if said command priority of the program wanting control is greater than or equal to the residual priority of the program having control;
• and,
• communication means connected between said control means and said loads for communicating the command instruction to said load.
