Abstract
A numerical controller includes a control section for controlling operation of a machine, an application section which is separated from the control section and adapted to input data into the control section and to monitor a control status, and a communication network for connecting the control section and the application section. This structure makes it possible to reduce the overall size of the numerical controller. A program for a new function or an abnormality diagnosis program is also transmitted from the application section to the control section when required.
Claims4
A numerical controller comprising:
- a control section for controlling operation of a machine;
- an application section which is separated from said control section for inputting data into said control section and for monitoring a control status;
- communication means including a network for connecting said control section and said application section;
- system program storage means provided in said application section for storing a system program for a function that is not supported by said control section;
- judgment means for judging whether an NC program sent from said application section to said control section includes a command which requires the system program for the function that is not supported by said control section;
- and
- transmission means for transmitting the system program for the function from said application section to said control section when said judgment means judges that the system program of the function is required.
