  1. Btw, it is nearly impossible to hard-brick a V570 or any of the enhanced PLCs. The PLC has a piece of un-programmable software/code which handles the initial load of the PLC. Even if you erase the entire FLASH / MMC of the PLC, this software will still remain, and it will allow you to burn the FPGA, Boot as OS.
  2. Well, It's installshield and it is doing exactly what it says. The installer needs to uninstall the current version in order to install the new one, When you check the "Keep old version", it simply copies the current version to another directory, changes some config file, copies some other files to that directory, creates a shortcut, and only then asks you if you want to uninstall.
  3. Just to understand, you just open a project from UniLogic using the regular Project->Open, select a file from a usb flash drive and this happens? I'll check that anyway (I'm not sure if I'll be able to reproduce it). As far as I remember, the notifier is not involved at opening a project, so it shouldn't cause that kind of a problem.
  4. Ahhh? UniLogic is totally free of charge. Please contact support@unitronics.com , or call them, and they will be able to help you.
  5. Are you downloading it to the external SD? Is there a chance that the external SD has been locked? (There is a system tag regarding the SD, with a member called "Locked" or "Is Locked") Rebooting the PLC if that happens can sometimes help.
  6. Please send your request to support@unitronics.com
  7. @Ofir, Can you please handle the request of Cora to get a Beta version?
  8. A lot of things have changed since then. On Feb 20187, when UniLogic 1.23.25 was released, it first introduced the Layers, and Elements Grouping
  9. Do you have an capture of the error? (An error message of some kind)
  10. Yes, it was already implemented and would be available on the next release of UniLogic.
  11. A timer tag has the following members: Preset Current Out The Out bit is what you used for telling if the timer has activated. Preset will give you the value that the timer is starting to count from, and the Current is the time left. Preset - Current will give you the elapsed time. You can attach a Timer Box element in the HMI to the timer in order to see Preset, Current or Elapsed
  12. OK. I was able to reproduce the problem, and it will be fixed on next release.
  13. General.OFF is a bit which is always set to 0, while General.ON is a bit which is always set to 1. There is no point of defining a periodic Register with General.OFF in their Active bit, because it will always be inactive. It's like writing a function in any programming language, and then when you are done, you comment it out. Why are you trying to assign General.OFF info a bit you've created? The bit has a value of either 0 or 1, if you didn't put any value into that bit with powerup-value, by ladder or by HMI, then it will be 0. If that bit is not retained, and the CPU or the PLC are restarted, then the bit will be 0.
  14. OK, if you are sure that the ladder code that you've shown me is being executed, then I have no idea why it doesn't work. I could debug it better if I had the project. You can also debug it by putting in increment after the PrefixToUpper, so you can see with Online debug (or with HMI element) that the number is being incremented (and it should increment only once). You can also store Prefix Tractor Serial No into another string tag, so you could see its value after the function was called.
  15. I tested your code, in a c function downloaded to the PLC, and it works. Can you send your sample project, or at least a screen capture of the ladder call to that function?
