  1. CJ2M CF Card Formats

    Thanks, this worked perfectly! Though I did previously try re-partitioning the card to 2 GB using other software, so I'm not sure why this didn't work.
  2. Hello, I am writing a VB.NET program that uses the CX Server Communications Control to communicate with a CJ2M CPU. I am able to upload and download programs just fine (using the UploadProgram and DownloadProgram functions). However, I hit a snag when the program uses function blocks. In this case, I can upload from the CPU OK, but when I try to download it seems that the function block file (.fbl format) is not downloading properly. The program file (.bin format) goes OK, and it recognises that there is a .fbl file to send afterwards, but it seems that nothing is actually getting sent. Has anyone seen a similar problem before, or have any relevant experience? Just let me know if further detail required. Thanks!
  3. CJ2M CF Card Formats

    Hello all, I'm trying to run a software update on an Omron CJ2M CPU. I want to do this from a CF card, since I have to run the update in the field. However, when I put a generic CF card in the slot (with the appropriate REPLACE.OBJ file on it), and restart the CPU (with the correct switch setting, on pin 2), it doesn't work and I get a card transfer error. The card is a 4GB unit, formatted to FAT16. Strangely, when I use a card purchased from Omron (at great expense), it works fine (with the procedure described above). So, my question is: Why does the Omron card work while the generic one doesn't? Have Omron marked their CF card in some proprietary way to ensure that we all have to buy their products? As far as I can tell, both the Omron and generic CF cards (both work with my PC reader), and both use the same FAT format. Thanks!
