Control device, machine tool, and displaying method

Abstract

A numerical control device includes a display, a memory, and a CPU (central processing unit). The display displays an image based on image information stored in a video memory. The memory stores internal information used when a failure occurs in the numerical control device. The CPU includes a code creator and a display controller. The code creator creates a matrix two-dimensional code of the internal information stored in the memory. The display controller synthesizes image information stored in the video memory with a matrix two-dimensional code created in the code creator to display the matrix two-dimensional code on the display.

Description

technical field

[0001] The invention relates to a control device, a working machine and a display method. Background technique

[0002] Conventionally, a control device such as a numerical control device equipped with a display mechanism and controls the operation of a machine tool using numerical information and a servo mechanism is known (for example, refer to Document 1: Japanese Patent Application Laid-Open No. 3-78005).

[0003] In addition, when a defect occurs in such a control device, it is necessary to output, for example, the version and revision of the software used to operate the control device, the state of the internal memory and I / O (Input / Output), etc. The internal information of the device (hereafter referred to as internal information) is used in the case, and the output internal information is transferred to the manufacturing place of the control device.

[0004] In the numerical control device described in Document 1, by including a communication control...
