  1. 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)
  2. 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?
  3. 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
  4. 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
  5. 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
  6. 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
  7. 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
  8. 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.
  9. Hello, Is it possible to put an extention cable in the SD slot? I need to access the SD slot without opening the panel door. Also, is it possible to download/View trended data/graph form the SD card using SD Card Explorer via Com Port? Thanks in advance!
  10. hi all, i would like to ask if is it possible to save all 8 trends from a v1210? i need to save at least 5. also how many tables can i save on the sd card? thanks
  11. My PLC is V350-35-T2 I have been having trouble displaying in my PLC a trend written to my SD card. I am able to write the trend to the SD Card and view it in the SD Card Manager but I am not able to view it in my PLC. I write the active Trend to a file called InnUt.utr When I try to use the "Trend from SD" variable in another display, it displays nothing. When the file "InnUt.utr" does: -exists the "Trend load error bit" is "0" -NOT exists the "Trend load error bit" is "1" So I must have the filename and folder correct in my program. Can anyone help me figure out how to display the t
  12. Hello, I am working on a project that requires recording the trending data from 4 separate trends to the SD Card. They want to record the data "no less than once every 5 minutes". I based my code off of the program in the examples file in the help menu and was able to get a single trend screen to record (I did it on the v570 for testing) based on a series of timers. The code worked fine however when I used the identicle code for the v1210 (setting up a single trend screen for recording) my start->trend SD Status message reads 256 which I assume is "failed to open file". Does anybody
  13. I have a V350 with trends and csv to SD. It works well but sometimes when the customer switch on the PLC we see the SB217=0. If you remove the SD and insert again the error is the same. I have seen that the only way to back to run is remove SD from OPLC, to insert in a PC doing nothing more and back to the OPLC. The application is a datalogger, if we have problems with the SD we will have a serious problem. Any idea to resolve it?
  14. People who see the SD Card Explorer in action usually sometimes wish to have the same functionality in their own application.Some of them contact Unitronics in order to get some details on the protocol, or ways that they can do the same, while others fear from the worst: that it's a lot of work.I know very few people that will be happy to write the whole protocol by themselves.The only guy I can think of in that matter is Ash Nielson... I have no idea where he gets his strength and energy from, but the solution for this problem is actually simpler than you think.You don't have to be energetic
