Posted 18 May 2013 You have no backup on your computer? If so the program is lost - when deleted from the memory in the PLC there is no way to recover. Share this post Link to post Share on other sites

Posted 18 May 2013 Never power off a PLC without doing a backup first. It's RAM memory in those units, so just like powering off a PC with a document open, when the power goes away the RAM goes blank. There's no method to recover from that other than write a new program. Share this post Link to post Share on other sites
