Posted 12 Mar 2020 It won't ask you for the password when you clear the PLC. If you don't have the original program on your PC than we cannot help you. 1 person likes this Share this post Link to post Share on other sites

Posted 9 Sep 2020 (edited) But it should not when you press initialization. Updating the firmware might also clear your PLC program:https://www.mitsubishielectric.co.jp/fa/download/software/detailsearch.do?mode=software&kisyu=/plcf&shiryoid=0000000051&lang=1&select=0&softid=1&infostatus=8_1_1&viewradio=1&viewstatus=&viewpos= Edited 9 Sep 2020 by Gambit Share this post Link to post Share on other sites
