Siemens S7-200 SMART decrypted successfully, level 4 password POU encryption can also be cracked.
For SMART password cracking... The software is priced at US$30,000 globally.
I think S7-1200 is now the best choice for use in small projects ... and in order not to quack projects = do not order them in China
я думаю S7-1200 сейчас лучший выбор для использования в небольших проектах... и чтобы не крякать проекты = не заказывайте их в Китае

Is it easy to unload a program from an S7-200? Or not really?

The control program, in fact, is nothing tricky.
The usual "relay" control of all sorts of things, such as hydraulics, pumps, valves and other rubbish, but ...
There is a timer code for 360 work shifts of 8 hours.
The timer counts only when some output is turned on, such as turning on the hydraulic pump of the pressure amplifier, that is, when the machine is running.
When the timer counts down to the end, the flag with the address M13.0 is set , like, all guys, pay money!
What is this if not extortion! It is impossible to clear the flag in any way, except for connecting the debugger, which requires a password!
How ugly it is and who programmed it, either the Chinese or our intermediaries from Moscow, I, of course, do not know ...
But I want to say: Well, you guys are goats!
PS: Interestingly, 360D is written on the PLC case with a marker. At first I took it for a password, then, of course, the real meaning of this inscription became clear .
By the way, the first version of the programmer was most likely a working one.
This rotten stub of a mouse cable was to blame!
