#18 CPU hardware protection through programming

[Ankur]

Hi,
First of all thank you very much for such a great library which helped us in our routine job.
We are protecting our S7-317 CPUs with hardware protection password at level-3. But those passwords are very difficult to manage. So we found another way to protect coding i.e. SFC109-"PROTECT". But one negative point about that is it protects only in RUN mode of CPU but when the CPU goes in STOP mode, the entire coding is open to read/write.
Can you please help us in this regards? We want to protect the CPU through password but that password must be editable through coding OR how to make SFC109 block protect the coding even in STOP mode?

Thanking you in advance.
