This video major introduce user operation log.
Hello, welcome to the touch screen operation video tutorial, today we talk about the user operation log. The function of the operation log is to record the detailed operation records that the user wants in the HMI, if a certain time triggered a button, or a certain time out to modify a value, etc. This component is a list of components to show the detailed operation records in the form of a list, and you can query or export the records, the operation method is, click on the component, select the list, click on the operation log, open the property page, you can see the list with date, time, user name and operation log, these contents can be selected to check, you can check as needed, here to cancel the line number, the default sorting method is descending order, showing the newer data, you can change to ascending order, to show the older data in front, here to select the default descending order, date format, separator, time appropriate can be selected, the row spacing is 5-255, and then look at the table drawing, you can choose the colour of the table, line type, the row separator check, and then look at the query, check the use of the query function, the query has four types, the first is a query by date, the second is a query by time range, the third is a query by order, the fourth is a query by user name, the query needs to specify a query trigger bit, when LB0 becomes 1, it displays the filtered results, for When LB0 becomes 1, it will show the filtered result, when LB0 is 0, it will not be filtered, the query register needs to be determined, for example, enter LW100, then LW100-102 is the register corresponding to the year, month and day to be queried, the query by time range needs the starting and ending year, month, day, hour, minute and second, the query by order, for example, the specified register is still LW100, when it is equal to 0, the query is for the day, when 1 is for yesterday, and so on, and In addition to the manual control of the query, there is also a register to control the query, such as the specified LW0, when it is equal to 0, it means query by date, 1 by time range, 2 by order, and 3 by user name. We will use the date query as an example. When LB1 is ON, the export operation is performed. The export can be done to a specified location, such as HMI, SD card or U disk. For example, if you specify a register LW0, then LW0=0 means export to HMI, equal to 1 means export to SD card, equal to 2 means export to U disk, take export to specified location as an example, the directory name of export can also be modified by yourself or use a register to specify the directory name, also up to 16 Chinese characters or 32 ASCII codes; export progress register, for example, specify a register LW200, when LW200 equals to 100, it means export has been completed, the way to export csv Exporting csv can be divided into daily export or single file, daily export is to export an operation table every day, if it is a single file, then all operations are displayed in a table.
You can also customise the file name, and if the Use password function is ticked, enter the password when opening the exported csv file and click OK. Change the size, the operation log also requires the control settings to be ticked to record operator actions, the same for the data entry component, record operator actions, click OK. The following offline simulation, click on the switch you can see this side of the operation record out, but the user name is empty, because there is no login user, and then now log in, you can see that there is a user name, modify the time, the following demonstration of the query function, x month xx, click on the query, you can see x month xx operation record, right, out, and then click on the query, and then demonstrate the export Click Export, and when the export progress is 100%, the export is complete.
