  1. That's it, thank you both. I'm still surprised you can paste elements, and move them with the keyboard when the screen is locked. Is this the intended behaviour? If so, the help could be improved to explain that.
  2. The Element isn't locked - I tried locking it, and that prevented the cursor keys from moving it. The screen isn't password protected (if that's what you mean), though there are other password protected elements in the project.
  3. Hi, I've just upgraded to UniLogic 1.29.111, and I've noticed I can't change the size or position of HMI elements with the mouse or properties editor. I can move them with the cursor keys, but that's all. Also, the "Arrange HMI elements" buttons stay grayed out when multiple HMI elements are selected. Is this an issue with this version of UniLogic? Anything else it could be? It's a fairly large, complicated project that's just been updated from 1.18.60. Sandy
  4. Resurrecting an old thread, but I just found a slightly different solution: Click on a Data Tables Section of the solution explorer Click on the Data Tables tab in the ribbon, then Upload Data Table Files from SD. Choose IP/USB as you usually do an connect to the PLC. The path at the bottom of this window is where the Data Sampler Files are saved to. The system creates a subfolder with the name you specified when defining the Data Sampler. I hope that helps someone!
  5. Hi, When I click on "Upload Data Sampler files from SD" it appears to work, and I get a message which scrolls through a few files before telling me it completed sucessfully. However, I can't find the files on my computer. Where are they saved? Kind regards, Sandy
  6. Hi, Is it possible to do safe remove of aUSB Stick/DOK from the ladder or a UI element? I'm saving a data row to SD, then the copying it to a DOK, all of which can be done from the ladder, using the status codes to avoid timing issues. I'd like to avoid the "DOK Unsafe Remove" warning that appears. I always get the same warning after using the safe remove button on a File Browser UI element, so this isn't a suitable workaround.

  7. Hi, I'm trying to build a log for my system using the Store DTI to File function. This runs after the struct containing the date is inserted into row 0 of a table, which should be appended immediately to the log file. The writes are sufficiently spaced (~30 minutes) that the SD write interval isn't an issue. I've found that when using option 2 "Only CSV" for the "Create CSV" input (F), the file is simply overwritten, and only ever contains 1 row. Option 1 "Create CSV File (All - udtf,csv,csv.zip)" does append correctly. In both cases "Append to File" (E) is set to 1 "Data will
  8. Thanks for catching that, I should know better than that by now. I'm not sure how it worked before - I might have been doing enough processing to slow the scan time right down. I ended up measuring the pauses, ie. by looking at when the number of bytes waiting stops changing. a 50ms timer worked nicely for this system.
  9. Hi, I'm trying to build a snooper that works on a modbus RTU network, to test a controller built by a third party. In this situation the Unistream is neither a master or slave, so the built-in modbus RTU configuration isn't suitable. I'm struggling to to get messages recieved consistently using the COM Rx ladder block. (it doesn't help that this ladder function isn't documented in the help file, specifically how it determines message boundaries in the absense of STX/ETX characters). I'd like to know that each time the "Data Arrived Bit" goes high, the first "RxLength" bytes
