Abstract
A numerical control device including a CPU for numerical control, a CPU for HMI, a display circuit and a restarting circuit configured to restart the CPU for HMI using the CPU for numerical control. The numerical control device further includes a display task monitoring unit, a determination unit configured to determine an abnormality of the operation condition of the display task by the CPU for HMI, using the display task monitoring unit, and a restarting unit configured to restart the CPU for HMI based on a determination result by the determination unit.
Claims8
A numerical control device including:
- a CPU for numerical control configured to perform numerical control;
- a CPU for HMI configured to execute an operating system and an application software for conducting HMI function, and output command for displaying graphic data;
