Embodiment approach 1

[0027] figure 1 It is a diagram showing the configuration of Embodiment 1 of the ladder program generating device according to the present invention. The ladder program generating device 100 according to the present embodiment generates a program by inserting a programming item at the position of the cursor by moving the cursor on the grid of the editor screen corresponding to the operation of the program generator in the editor mode. Ladder diagram device. The ladder program generation device 100 has a control unit 20 and a display device 10 with a touch panel. The display device 10 with a touch panel has a display unit 11 and a touch panel 12 . The control unit 20 has an operation detection unit 21 , a display control unit 22 , and a processing execution unit 23 .

[0028] The display unit 11 displays an editor screen for creating a ladder program in a ladder format. Touch panel 12 is arranged to overlap display unit 11 .

[0029] The operation detection unit 21 detects...

Embodiment approach 2

[0049] Figure 8 It is a diagram showing the configuration of Embodiment 2 of the ladder program generating device according to the present invention. The ladder program generation device 100 according to the second embodiment differs from the first embodiment in that the control unit 20 further includes a test mode processing unit 24 .

[0050] As a control device in the FA field, PLC can handle bit information and word information. In addition, it is possible to assign these information to registers and substitute information, and it is a "monitor" to read the value. Monitoring is reading information from registers, but conversely, information can also be written to registers, this operation is called "testing".

[0051] As for the operation during the test, usually, for the bit register, use the operation of the pointing device, press the ON or OFF icon to perform the ON / OFF operation, and for the word register, use the keyboard to directly input the value.

Abstract

The invention is provided with: a display section (11) that displays an editor screen that creates a ladder diagram; a touch panel (12) installed superposed on the display section (11); an operation detection section (21) that detects an operation performed in the touch panel (12); a display control unit (22) that displays a representative icon corresponding to one programming item that can be inserted in the ladder diagram in the editor screen, said representative icon being displayed on the display section (11), and when the operation detection section (21) detects a touch operation on the touch panel (12) at the position in which the representative icon was displayed, displays a display frame in which derivative icons corresponding to other programming items that can be inserted in the ladder program are placed around the representative icon, said display frame being displayed on the display section (11); and a process execution unit (23) that when the operation detection section (21) has detected that a finger that performed a touch operation has been removed from the touch panel (12), or has detected that a finger that performed a touch operation and was subsequently dragged has been removed from the touch panel (12), inserts the programming item corresponding to the representative icon or derivative icon that had been displayed at the detected finger removal position, said programming item being inserted in the ladder diagram.

Description

technical field [0001] The invention relates to a ladder diagram program generating device. Background technique [0002] Currently, when a program creation device creates a ladder program for a programmable logic controller (PLC), the program creator uses a pointing device such as a mouse to select icons displayed in a list on a toolbar or a pallet. Insert it into the ladder diagram on the editor screen, or manually enter the mnemonic using the keyboard. [0003] Regarding the method of selecting a programming item with a pointing device, when selecting a desired programming item from icons of a plurality of programming items displayed in a list, an incorrect programming item may be selected due to an erroneous operation of the pointing device. [0004] In addition, with regard to the method of manually inputting mnemonics using a keyboard, the input operation is cumbersome, and the workload of the program creator increases. [0005] Patent Document 1 discloses a techniqu...
