So I am in the midst of a lengthy project migrating a Bio-gas plant from a S7-400 to a CLX and replacing the old WinCC Scada with (sadly) FTSE.
The old S7 is destined for the bin in a few months time, but I need to add a couple of DB's so we can migrate the IO from the Siemens to the CLX, the CLX will then write the values / bits to the Siemens PLC via Derived Tags and Kepware until the CLX then takes over the control.
I have the original Step 7 project from when the plant was built, along with all changes over the years, so all straight forward so far.
Here is my problem though: the project is read-only and the password is unobtainable as the OEM went out of business years ago, so I can't just add my db's and download them.
I can and have done an upload to the PG, so surely it's a case of doing that, changing the protection in the HW Config and re-downloading?
(The card in the S7-400 is a RAM not an eeprom, so that shouldn't need anything doing)
If that is the case, was security really that slack? How would this prevent someone doing anything?
Or have I completely missed the point of the old password protection.
