  1. 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
  2. Hello, My project involves filling a data table with real time data, and in order to progress through the experiment it needs to read the last 100 values recorded, sort them, and then get the resultant range. So I only need to read the last 100 values of the column I am currently fillling up during the program, but I only see a function that copies the entire row to a vector. This wouldn't work as the column has more numbers than the MI memory has operands. Is there any way to only put part of a column into a vector? Thanks in advance!
  3. Hello, I'm using UniLogic and I want to copy only a column for example recipe names. In the VisiLogic software this is possible with a function under data tables. How do I do this in UniLogic? Thanks, Jan Martijn Lenselink
  4. I want to copy from an Array (INT16 × 15) to a single DTI cell which holds a similar array. In effect I'm trying to copy one dimension to another. Does the function 'Copy array to column in DTI' allow this? The compiler allows me to set the function up, but no data seems to be transferred. Regards, Robin Proctor
  5. We have used Pcom to communicate to the data tables in the vision series. How do you recommend communicating to the data tables with the unistream? I would like to connect to a database that I built in Ms access. What would be recommended method?
  6. Hi all, I've been spending almost one day looking how I could compare to ASCII strings without success unfortunately. The idea is to compare a string from the HMI (username) with a String inside a user account data table loaded into a struct row after row. This is just to be able to make a kind of login function with user and password protection. Guillaume
  7. I am using a V1040 with a Data Table in which I need to write/edit values. The Properties setting for allowing this is greyed out. Can someone tell me perhaps why and how to fix it? Thanks.
