Embodiment approach

[0027] figure 1 It is a figure which shows the structure of the control system which applied the programmable display concerning embodiment of this invention. The control system 103 includes a programmable display 100 and a plurality of control devices 101 1 ~101 n , And the programmable display 100 and the control device 101 1 ~101 n Connected network 104. Programmable display 100 and control device 101 1 ~101 n 1 of them communicates, using a 1-to-N (N is an integer greater than or equal to 1) communication method. The programmable display 100 has an operating state display unit 102. The programmable display 100 uses the operating state display unit 102 to notify the operator of the state of the programmable display 100 itself and the control system 103.

[0028] Here, the operating state display unit 102 has a structure having a green LED 102a whose emission color is green and a red LED 102b whose emission color is red. The display color of the operating state display unit 10...

Abstract

The programmable display has: a display for displaying a screen showing the operating state of the connected control device; It does not depend on whether the display is in the screen saver state, and can be turned on in one of a plurality of lighting modes, and is a display unit different from the display; Lighting is performed according to the lighting mode corresponding to the state of the device.

Description

Technical field [0001] The present invention relates to a programmable display which is connected to a control device and has the function of displaying information of the control device and setting the control device. Background technique [0002] The programmable display is connected to control devices such as PLC (Programmable Logic Controller), and has the function of displaying the operating status of the connected control device or sending control instructions to the control device through operation input. Used in various industrial fields. [0003] The function of the programmable display for screen display and control of the control device can be freely designed by the screen designer through dedicated screen creation software. In addition, the programmable display is used as a monitoring and operating device of the control system, and is viewed or operated by an operator. That is, the user of the programmable display is both a screen designer and an operator. [0004] Sin...
