  1. Can you try with a different USB stick? I've already encountered problems when the stick had corrupted sectors. I see that you already mentioned that you've tried 2 different sticks, but if both of them of the same brand, then maybe it doesn't like it. @NoamM, your assistance will be welcome (Maybe debug it, or get a verbose log)
  2. There is another DLL called Unitronics.DataTables.dll, which uses the .Net driver. It lets you write and read values from data tables.
  3. @leen It was added to the working plan. You should see this feature in one of the next versions (1.37 or 1.38).
  4. It's not a class, it a delegate (a pointer to a function) where progressStatusChanged should be a function that returns void and gets RequestProgress requestProgress as parameter. Looking at the code, I see that it can handle well progressStatusDelegate being null, so you can just pass null instead.
  5. Yes, it's a known issue on version 1.35.227 The fix to this issue will be included in UniLogic 1.36
  6. Use .Net communication driver. If you create a PLC object then it has a Property called SD, which let you do some file actions with the SD Card. Here is a code example, written long time ago, which has an SD Card explorer example, with its sources code. https://downloads.unitronicsplc.com/Sites/plc/Visilogic/Programming tools for developers/SD Card Explorer Lite.zip
  7. No, it was not added. I assume that you need it since you don't have an SD card in your PLC, right?
  8. Hi @ORSO2001 Thanks. I hope that your ticket has the project and also all the information (screen captures, or videos, or anything that can help R&D understand what is not working properly)
  9. Please note, I have fixed this issue. On next UL release, you should be able to load that old retained tags hex file, while the new one that I sent you will not work.
  10. If I understand you correctly, you want to change the Initial Value of retained tags from the PLC, right? (Initial value of a retained tag is the value it gets when you download the program on the first time, or you call Init retained tags). In this case, the values are compiled into machine code, so it's not possible. If you want to just change values of retained tags, then you can create HMI screens for it, and maybe also edit the values from the UniApps (I need to check if it's possible, but even if can be done, then it's very uncomfortable because it was not meant for it)
  11. I'm not sure what your retained tags contain (Which tags and which structs). There is a chance that the upgrade caused the address of some retain tags to change (due to some retained tag that were of type of Reserved Structs that were changed from version 1.25 to 1.35), so in this case copying the values from the original project to original (old) address would be wrong, since the address is not correct. You can send me the original project (in version 1.25), and the Retained tags file, and I will look into it.
  12. Did you already download the project to the PLC? If so, the retained tag should have their valid values before you've upgraded it. Is that the case? If so, then there is no need to download the retained tags memory again, but I would upload the retained tags from the PLC again.
  13. No, you can't write to the Username tag in the UAC struct.
  14. 45 minutes is a lot of time. What PLC model is it, USP or US5/7? If it didn't finish after that time, then I think that something went wrong during the upgrade process, but you should be able to recover the PLC (Depending on the Model) @NoamM Please reply.
  15. In the current UniLogic version it's not possible, but it can be done. I'll open a feature request.
