s7-200 password

[ratcliffe_ic 2]

Does anyone know of a way to upload a password protected program without knowing the password. Is there any work arounds without resorting to clearing the PLC memory and starting from scratch as described in the HELP files.

the only thing i can suggest is deleting the memory from the cpu. if thats not possible then your out of luck as there is no "back door" way in.

or at least try several common password combo's first, if there's a TD200 scroll through all the messages first and see if someone's dropped the password there, if im passwording anything with a TD200 on it i always add a spare screen with a password reminder. Other than that try some common ones first like '0000' etc to see if you hit it lucky otherwise its a case of clear the memory and start over
