I have a S7-300 PLC that requires a password for online operations, I can not use the S7CanOpener to defeat the password. The supporting company is defunct. Can not reach anyone. Any ideas on how to get around? or do i have to reset processor completely?

Hi homer874. Try to contact this person: andi@rothenbacher-gmbh.de. He will need a written declaration from you that you have legitimate reason to access the program, and he wants a fee as well (approx 1000 euro !).
