In this embodiment, before the displaying of the data table, the method further includes: and creating a page with a preset style for the touch screen, wherein the page comprises a data display table, a table number input area and a reading key.
In this embodiment, the page of the touch screen is created and imported to the touch screen mainly by the computer. The page style, for example, the size of the data display form in the page, the position of the form number input area, and the position and shape of the reading key, can be designed according to actual needs, which is not limited in this embodiment.
Taking the page shown in fig. 4 as an example, in fig. 4, the data display table in the page is 6 rows and 4 columns. For example, the data name display line can be sequentially a line number, an x coordinate, a y coordinate and a z coordinate, and the data displayed below the column corresponding to the line number is the line number stored in the register address with the beginning of D in the grid, and the data displayed below the column corresponding to the x coordinate is the x coordinate value stored in the register address with the beginning of D in the grid. Each grid from the 2 nd row to the 6 th row is respectively connected with a register address in the programmable logic controller for displaying data in the corresponding register address. The box behind the table number below the data display table is used for the relevant staff to input the serial number of the table expected to be viewed, for example, to input "1", and after the table number "1" is input, the reading key is triggered, so that the data display table can display each data of the table 1.
After the touch screen acquires the page with the preset style, the corresponding element of the reading key in the programmable logic controller is required to be set, so that when the reading key is triggered, the programmable logic controller stores the data of the memory area to be displayed of the register of the programmable logic controller into the display memory area of the register.
After the touch screen acquires the page with the preset style, connecting the touch screen acquiring the page with the preset style with the programmable logic controller, and associating the reading key with a corresponding element in the programmable logic controller. Then, the element corresponding to the read key is set, for example, the element corresponding to the read key in the programmable logic controller is M82, so that when M82 is triggered, the program executes an operation of storing data in the to-be-displayed storage area of the register of the programmable logic controller into the display storage area of the register of the programmable logic controller by programming the programmable logic controller. Wherein, the programming mode includes but not limited to: a programmable logic controller ladder diagram; the to-be-displayed storage area is a storage area of data in each to-be-displayed table in the register, and the to-be-displayed storage area stores data in a plurality of to-be-displayed tables; the display memory area includes register areas corresponding to register addresses corresponding to respective cells in a data display table in the touch screen.
After the preliminary preparation work, the data table can be displayed through the touch screen page.
101, inputting a serial number of the table expected to be displayed in a table number input area on the touch screen page and triggering a reading key.
After the touch screen acquires a page with a preset style, the data display tables and the keys in the touch screen are associated with the programmable logic controller and the programmable logic controller is programmed, data in each table can be checked through the touch screen. For example, if the relevant staff member desires to look at the relevant parameters of table 1, the relevant staff member may input "1" in the table number input area of the touch screen, i.e., the box after the word "table number", and then click the read button.
And 102, the touch screen acquires the serial number and sends the serial number to the programmable logic controller, and the programmable logic controller receives the serial number of the table which is expected to be displayed and sent by the touch screen and stores the serial number in a register of the programmable logic controller.
Since the table number input area in the touch screen is connected to a register address of the programmable logic controller, as shown in fig. 4, the address is D990. Therefore, when the relevant staff member inputs '1' in the table number input area of the touch screen, namely the frame behind the word of the 'table number', the touch screen sends the data '1' to the corresponding register of the table number input area in the programmable logic controller.
In this embodiment, when the programmable logic controller receives a trigger signal of the read key, it needs to store data in a certain table into the display storage area of the register. The specific position of the data of the table in the memory area to be displayed in the register is determined according to the table number stored in the register. Fig. 4 is a schematic diagram of a to-be-displayed storage area and a display storage area of a register, where the to-be-displayed storage area includes storage areas of tables, addresses of the register are displayed in the storage areas, and corresponding data are stored in the corresponding addresses.
103, the touch screen acquires the trigger signal of the reading key and sends the trigger signal to the programmable logic controller, and the programmable logic controller receives the trigger signal of the reading key sent by the touch screen and stores the data at the position corresponding to the serial number in the storage area to be displayed in the register to the display storage area of the register based on the trigger signal of the reading key.
Because the reading key has corresponding elements in the programmable logic controller, a trigger signal of the reading key is generated after a relevant worker clicks the reading key. The touch screen sends the trigger signal of the reading key to the programmable logic controller, so that an element corresponding to the reading key in the programmable logic controller can be triggered.
And after the programmable logic controller receives the trigger signal of the reading key sent by the touch screen, an element corresponding to the reading key in the programmable logic controller is triggered. Then, the program in the programmable logic controller can find the position of the data of the corresponding table in the storage area to be displayed of the register according to the table number stored in the register, and store the data in the display storage area of the register.
And 104, sending the data stored in the display storage area to the touch screen by the programmable logic controller, and receiving the data stored in the display storage area by the touch screen and displaying the data in a data display table.
Since each cell of the display data in the data display table in the touch screen is connected to a register address in the programmable logic controller, as shown in fig. 5, the data at the beginning of D in each table is the address corresponding to the cell. Therefore, when the data in the display storage area of the register is updated, the programmable logic controller correspondingly sends the data stored in the display storage area to each cell of the display data in the data display table of the touch screen. And each grid of the display data in the data display table of the touch screen is displayed in the grid after the data stored in the display storage area is acquired correspondingly.
105, if the data displayed in the data display table is modified, triggering a storage key;
when data display is carried out through the data display table, related workers can check the parameters, if abnormal parameters are found, the parameters can be changed through the touch screen, and the modified data can be stored through triggering the storage key.
106, the touch screen acquires the modified data and the trigger signal of the storage key and sends the modified data and the trigger signal of the storage key to the programmable logic controller, the programmable logic controller receives the modified data and stores the modified data to a corresponding storage position, receives the trigger signal of the reading key sent by the touch screen, and stores the data of the display storage area of the register to the position corresponding to the sequence number in the storage area to be displayed in the register based on the trigger signal of the storage key.
Because each grid for displaying data in the data display table is connected with one register in the programmable logic controller, when data in any grid for displaying data is modified, the touch screen can send the modified data to the corresponding register of the display storage area of the programmable logic controller. Because only the table which is expected to be displayed currently is stored in the display storage area, and the data of the table is fixedly stored at the position corresponding to the table serial number in the storage area to be displayed, the modified data needs to be stored at the corresponding position in the storage area to be displayed. At this time, the data that is still before modification is stored in the corresponding position in the storage area to be displayed, and therefore, the corresponding data in the storage area to be displayed needs to be modified. In this embodiment, by triggering the save key on the touch screen, the element corresponding to the save key in the programmable logic controller is triggered, so that the program in the programmable logic controller executes an operation of storing the data in the display storage area to the position corresponding to the sequence number in the storage area to be displayed, thereby saving the modified data.
