  1. Dear Forumites, I have an issue with SD Card. For the first time SD card plugged into PLC, the PLC detects the SD Card and the System Bit (SB217, SB218 shows "1" ). Once the data is written to SD Card and if the card was removed from PLC, after copying all the data's and when SD card is inserted back into PLC it doesn't detects the card. I need to do lot of trial and errors to make the card detectable. I even tried with different make of SD cards such as Allen Bradley, Transcend, SanDisk etc still the problem persists. I followed the safe removal process and every time when I place the card in the PLC using SD Card suite I am formatting the card as per the webinar video series still I am getting this issue. The Controller I am using is V570. Can any one throw some light on this. An appropriate reply in this regard is highly appreciated. Thanks Vijay
  2. Hi All, I have enabled the web service utility of V-570 PLC. I am able to view the data's on the web browser, now I need to connect the same to the Plant network which has internet connectivity. So in that case what security measures do I need to take care of the PLC. Cheers Vijay
