Posted 30 May 2014 1. The PLC is password protected which means you'll need a password to modify anything in the PLC (including clearing the memory). You will need the original password. 2. Just for info: It's not allowed to discuss password hacking/cracking on the forum so please do not ask for that. Share this post Link to post Share on other sites
Posted 30 May 2014 Mr7 wrote he has a copy of the program, so, if I understood correctly, he want to format the PLC memory. Share this post Link to post Share on other sites
Posted 30 May 2014 Yes, but even if he has a copy, the PLC can still be protected by a password... Share this post Link to post Share on other sites
