  1. Hello, I'm working on a program that save multiple values in a data table and at the same time in a CSV file every 200ms. Every thing is fine when I look at my data table in Unilogic, every value is saved there every 200ms but for some reason, on the CSV file, the data from row 0 to the current row is appended again every 8 seconds or so. I can add my program if anyone can look at it. Thank you
  2. Hi guys, Is it possible to update values of a data table using an USB memory stick with Unistream PLCs?
  3. Working on a project where I need to email a zipped CSV file created from Data Sampling. I can structure and send emails with no problem. I can see the CSV file via file browser, but having difficulty sending the attachment. My goal would be to allow the operator to choose from a list of csv files that updates as the files are generated from Data Sampler tests. I have tried to link a tag where you configure the email so you can type in the file name on a key pad text box. the keypad entry does not have some of the characters needed to match the file name (ie. -_ etc.). Has anyone sent CSV email attachments and could point me in the right direction? Thank you for your input
  4. Dear all, I am using different data tables in a project, including saving and loading TDI from SD card. Some of the tables are "system" oriented like settings, and some tables are "user" oriented like programs and recipes. User should select a file by using HMI element: File selector browser . For now ALL DTI files are kept in the DT folder and selection is problematic. I need to separate each kind in a different subfolder, so the selection will be user friendly. The "Store DTI to a file" and "Store DTI to a file" ladder blocks is not giving the option for different sub directories , that would helped if exist. File selector browser is not supporting sub folders as well. Can I use differents folder path as part of the file name string? or any other way to manage subfolders? In addition, "Copy/Move file" and ladder elements, don't have the option to copy or move within SD card folders, but only to/from DOK. It would have helpful if possible to arrange the files by type of functions by ladder. any ideas? Any help?
  5. Hi all, I'm saving datas in a SD Card thanks to Visilogic. I've a problem with the file's name saved : I want its name to be the value in ML4-NumAffaires. For exemple it can be 83178. But instead of having this, I've -D-. I think it's a problem of space and conversion, but I don't manage to fix the problem. Thanks in advance for your help
  6. Hello, I'm try to write more than one dt to sd card. I cannot doit. Any ideas ??? I attach the ledder. I'm writing a one raw each 15 minutes than i want to append it to sd card It works but only for the first DT Best wishes, eng. Nikola Gramatikov
  7. I use trends and they fill up the SD card on the UniStream. I tried to use the file browser object to manage the SD card. Specifically I'm trying to delete the 'samples' folder created by the trends. When I try using the file browser and UniStream SD Delete (or the one in UniApps) after selecting the 'samples' folder I get an error Any ideas on how to do this correctly? Is something writing to the disk or not properly stopped? Right now I have to pull the SD card and delete it on my laptop then put it back into the PLC. Not very elegant and difficult to do remotely... Thanks!
  8. good morning i need to write a row in a temporary table in the ram memory this table contains one row and 12 columns, the first one is a long integer entred and the second is a string, both are entered with the keybord of the plc and the rest are integer with 100 velues in each cell and those are mesurment of voltage from the analog input one mesurment every 0.1 seconds during 100 seconds and i want those mesurments to be triggered by a button. once finished it has to coppy that row to a bigger table with the same columns but lets say 1000 rows in the sd cardso i can later use that informations to feed the analog output with the same voltage mesured with the same amount of time 0.1s until the first zero . i want all that to be controlled from the plc the writing and the copying and the search of the row later . is that possible and if yes, is there any exemple that might help me. thank you.
  9. Why does the "Store to DTI File" function create multiple files when I set "F" Parameter to #1 (Create CSV file). I expected just a CSV file, but it created a "*.UDTF", "*.CSV", and a "*.CSV.ZIP" on the SD card too? I would prefer the program only to save the DT to "*.CSV file". DTI Infolog Sub.pdf
  10. Hi, Is there any way to load a program into a UniStream controller via a microSD card or USB memory stick? The new software looks great by the way. Is there any thought towards developing the ability for online programming edits?
  11. Hello , is there is a restriction on the number of files in the directory "/data tables" on SD card?
  12. Hi, I'm trying to get trend from SD card to display on a V700. I cannot get any trend to display. I have checked that the trend does exist in the SD card via SD explorer and shows correctly in SD manager. I have stopped the writing of the trend when I loaded the HMI page with Trend from SD variable. The trend load error bit of the Trend SD variable is showing 0. The only anomaly that I can find is SB119 is constantly showing 1. I cannot find any literature about why SB119 is always on. Please help. Regards, Qinsong

    Copy/Move File from SD card DOK

    Hi, I'm trying to move data table from SD card to USB memory stick. What is the default DOK file path?
  14. Hi support and forum members I have successfully used the Visilogic project examples to log data using an SD Card. However, the example program uses SB13 to write data to the SD card every 1 second. This is far too frequent for my application. I want to log data every minute, or every 10 minutes. How can I reduce the write frequency? Do I need to use some delay timers? Can anybody assist me with the correct/optimal ladder for this. Picture of code attached. I'd also like to know how to display the free space in MB or GB left on the SD card Best Regards

    SD files timestamp

    Hi, What is the reason for difference between timestamp "last modified" of file written on SD-card, and the PLC time when this file has been saved? I have 3 hours difference between them. (I connect to PLC with FileZilla ftp client)
  16. Hi I have a project with USP-104-B10 (UniStream 10 inch) ַַ& Unilogic 1.15.70 and in the project I build a trend screen. Now I have to save the data into the SD card ,transfer the data to my computer and convert the data to csv and generate a graph. It's a very long process. how can I shorten it? can I save the data straight to csv? is there a software that can take the data format of the trend file and make a graph?

    Remove DOK safely

    Dear All, I am using the USB key to transfer some DTI...all works fine but sometimes, after I removed the DOK, a windows appears and highlighted me that I done this action in a not security way...and tell me to use the " safely remove DOK" !?...in the UniApp I have it but how I have to do to insert this "button" in the ladder...where I find the function? into the "external storage" I found only the BITs about the SD and DOK presences. thanks
  18. Hello. I have a problem that might be related memory capability in the SDcard. Suddenly (after a Power Off/Reset) all my trends stopped. When I open the trend it is empty and the Run/stop button displays Run. If I press the Run button nothing happens, but I am still able to open and view the "History" trends. Also all my trends had status -3; Save file error (File name may contain illegal character) (my file names are the same as when the trends was working). In my Project I use 12 data samplers/trends, 4-8 REAL variables in each trend, sampling interval 1s - 1min.The trends had been running for several weeks when the problem occured. After I changed my SD card to a new (empty) one, the trends worked again. So I assume that the problem was related to running out of memory on the SD. My SDcard is 16GB Do I have to delete history files from the Unilogic program to avoid running out of memory, or is this automaticcaly handeled by Unilogic? If I have to do it from the Unilogic program, do you have any examples on how to do this? Thanks!

    Store DTI to SD card

    Dear All, I have to store a DTI table, when it is full (1000 rows and 8 columns), in the SD card...and after I have to clear the table to start again with the recording of the data...how much time is needed to store compleately the table to enable the "clear DTI" ladder function? in the "help" I found an extimated time only if I use this function followed by a "load from file" function. thanks
  20. Hello, I'm doing a project where I have to save alarms to SD. I have a V570 with 2GB SD card (The SD Card is formatted with SD Card Suite). I set the SB352 (Write alarm history to SD) and it does that, it writes alarms directly to SD card. If I have some alarms in buffer (SI76 value is greater then 0) and I set SB352, the value in SI76 clears and ALARM.UAL is increasing in size. So I think the alarms are written to SD Card. The problem is when I use the FB "Show alarms" with "Alarm history" option. It shows the history, but after a PLC Init and Reset, the history is cleared. It shows the history from PLC Memory, not from SD Card. So, my question is how should I save alarms to SD and then display them? Thanks!

    Export Trend File to CSV

    Hello, (Unistream PLC and 10.4 Inch screen) I Try to export the trend data from a Datasampler to a CSV (EXEL) File I get it from the SD-card with filezilla. Sometimes the file will be generated and sometimes it won't I stop the data sampling and then i set the create CSV bit. in ladder function. But it not always generate the file (.ZIP) Is there an example how this file must be generated. I use Unilogic version 1.9 rev 19 I have tried a full download and so on but sometimes it works sometimes it won't Is there any example how this works. Thanks René

    Download CSV from SD

    I know it's possible with the Advanced Web Server to download a file from the SD to the PC via web explorer. Now I have a finished application where the customer needs to download the CSV without use the SD Card Explorer. Copy and paste all the application to the .vlp with the embedded webserver is a task for titans but I don't know how to start to make a simple application to download a CSV. It will be about chunks... Anyone can help me? Project: A PLC with IP 192.168.1.201 and a CSV called test. Download from internet explorer: http://192.168.1.201/EXCEL/TEST.CSV
  23. 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
