Abstract
There is provided an initializing method for a programmable machine controller, whereby various control parameters of the programmable machine controller can be initialized quickly. The initial values of the various parameters, stored in a random access memory for initial-value setting of the controller, are transferred to a blank region of another random access memory for storage therein (S1.about.S4), and then transferred to a read-only memory (ROM) cassette for storage therein (S5). When a command for parameter initialization is delivered with the controller loaded with the ROM cassette, the various parameters are initialized using the initial values stored in the cassette.
Claims7
A parameter initializing method for a programmable machine controller performing a control operation using predetermined memory contents stored in a read-only memory cassette, said method comprising:
- (a) storing in an initial value random access memory of said programmable machine controller initial values of various control parameters of said programmable machine controller;
- (b) transferring the initial values into a blank memory region of a debugging random access memory having predetermined memory contents;
- (c) transferring to and storing in said read-only memory cassette said predetermined memory contents in said debugging random access memory and the initial values of said various control parameters;
- and
- (d) initializing said various control parameters using the initial values stored in said read-only memory cassette, in response to a command for parameter initialization, after said programmable machine controller has been loaded with said read-only memory cassette.
A method for setting a read only memory with initial values for control parameters of a programmable machine controller in a numerical control unit, comprising the steps of:
- (a) determining the initial values of the control parameters;
- (b) storing the initial values determined in step (a) in a first portion of random access memory;
- (c) transferring the initial values of the control parameters from the first portion of random access memory into a blank region of a second portion of random access memory;
- and
- (d) transferring the values of the parameters into the read-only memory.
