Hello friends.
Is there a way to download a protected program to save it for the feature, and/or modify input-outputs in the program?
The company who programmed the machine and designed it was closed several years ago.
PLC type Siemens SIMATIC S7-200.
Pictures below will show what is happening.
Thank you in advance.
