Leo0n Posted May 1, 2014 Report Share Posted May 1, 2014 Hello everyone, I have a few questions about the software Unilogic and using it together with the USP-070-B10. First, what I want to know if it is possible to read the files on the SD card in the map "/DT" and especially the files for the data table because I want to show the user which files are on the sd card, but I dont want to use the uniapps menu. I have created now that everytime the user send a file over ftp to the PLC, the data table will add a new row with the name, but if the user change the sd card or remove a file from it, the PLC need to see this also. Second, I have created a data table with strings, if I'm trying to search for a specific string a column. But if the string is for example 10 long and the word I'm trying to search is only 4 long, I cannot find it. But if i make search first from 10 long and the second 9 and the third one 8 the value will be found. but the fourth value cannot be found with a length of 7. this mean that I can only search for 3 different lengths, but if the users insert more different values between 1 and 10, only a few values can be found in the data table. But if you use integers and search for integers he can find all the values. how can this problem been solved? the search value will be typed in a text box on the display. third, Is it possible to program on the PLC that if there are any excel files on the SD card to create a data table file on the PLC itself. then the user can send the excel file through TCP to the PLC and does not need to send the data table file. If someone could help me with this problems, you would be thankfull! Leon Quote Link to comment Share on other sites More sharing options...
