Embodiment approach

[0020] figure 1 It is a block diagram which shows the structure of the programmable display which concerns on embodiment of this invention. The programmable display 10 has a display unit 11 with an input function, an operation display processing unit 12, a backup / restoration processing unit 13, a communication driver 14, a communication interface (I / F) 15, a built-in flash ROM 16, a file system processing unit 17 and External storage medium interface (I / F) 18 .

[0021] The display unit 11 with an input function displays a screen corresponding to screen data and accepts a touch input on the screen. The operation display processing unit 12 processes screen data and touch input information acquired by the display unit 11 with an input function. Data is transmitted / received between the communication I / F 15 and a control device 20 such as a programmable controller. The control device 20 controls the driving of an external device to be controlled. The communication driver 14 pr...

Abstract

The invention provides a programmable display, which maintains match performance of versions for picture data and an operation software group, and can perform backup processing and reverting processing. The programmable display is provided with: a display portion (11) with an input function; and a backup / reverting processing portion (13) performing backup processing and reverting processing, in the backup processing, the picture data and the operation software group are transmitted from a startup system folder of an internal flash memory ROM (16) to a backup folder of an external memory medium (30), in the reverting processing, the picture data and the operation software group are transmitted from the backup folder to the startup system folder, the backup / reverting processing portion (13) performs backup processing and the reverting processing with group data comprising the picture data and the operation software group corresponding to the set function in the picture data as the unit.

Description

technical field [0001] The present invention relates to a programmable display, and particularly relates to a method for backup processing and restoration processing of screen data and operating software groups stored in the programmable display. Background technique [0002] Generally, screen data used for screen display on a programmable display is generated by a user running screen generation software on a personal computer or the like. The user uses screen creation software to perform layout and design of screen displays corresponding to production lines and the like. Transfer the screen data from a personal computer, etc. to the startup system folder of the programmable display using the screen creation software. The operating software group for executing the screen display corresponding to the screen data is transferred from the personal computer etc. to the startup system folder of the programmable display through the screen creation software. [0003] While newly t...
