Abstract
A machine control device capable of accurately rewriting a control program of a memory for controlling a mechanical device. The machine control device includes a first memory in which a control program is stored, a controller which controls operation of the mechanical device in accordance with the control program stored in the first memory, and a removable second memory in which a control program and a rewrite program are stored. The controller replaces the control program in the first memory with the control program in the second memory in accordance with the rewrite program stored in the second memory when the second memory is installed.
Claims16
A machine controlled by an operation comprising:
- a controllable element;
- a first memory in which a control program is stored;
- a controller, connected with said controllable element and said first memory, which controls operation of said controllable element in accordance with the control program stored in said first memory;
- a removable second memory, removably connectable with said controller, in which a control program and a rewrite program are stored;
- said controller includes means for replacing the control program in the first memory with the control program in the second memory in accordance with the rewrite program stored in said second memory when said second memory is connected with the controller;
- and
- means for activating the replacing means by connecting the second memory with the controller.
A machine controlled by an operation program comprising:
- a controllable element;
- a first memory in which an original control program is stored;
- a controller, connected with said controllable element and said first memory, which controls operation of said controllable element in accordance with the control program stored in said first memory;
- a removable second memory, removably connectable with said controller, in which a new control program and a rewrite program are stored;
- and
- said controller includes means for writing said new control program into said first memory while erasing the original control program in accordance with the rewrite program stored in said second memory when said second memory is connected with the controller and
- means for activating the writing means by connecting the removable second memory with the controller.
In a machine comprising a controllable element, a memory for storing a control program and a controller for controlling operation of the controllable element based on the control program, a method comprising the steps of:
- supplying a new control program and a writing program from an external device to the machine;
- writing the externally supplied new control program into the memory in accordance with the externally supplied writing program;
- and
- activating the writing step by connecting the external device to the machine.
