Hi PLC gurus
I am having some s7 plcs are password potected. But these are different types of protection.I can't communicate with the port of some s7 200 plcs . The port itself password protected.When I am trying to communicate with the plc it is asking the password. The other type in s7 300 is , I can upload or monitor the program . But I can't do any modification(download) even can't force one flag bit.
May I know the types of protection?
How the password can be assigned for protection? i.e. procedure
Can we break these passwords ?
Any help will be highly appreciated
