How to encryption PLC FB Code?

[Max1]

Hello CtrlX team

I have a question,I want to know how to encryption PLC FB Code? Thanks.

Could you please give some more information what exactly you want to encrypt?

• The code of an FB in a library? Compiled libraries include no open code.
• The code of an FB/application running on the ctrlX CORE? That is only available as compiled code.
• The project data on your PC?
• The project data on the ctrlX CORE? That can only be accessed with authentication and authorisation.
• Something else?

Hello,I just want that can only be accessed with authentication and authorisation,So How to accomplish it ?

[CodeShepherd]

Sorry for the similar answer but when putting your compiled program the control and also when you synchronize your project data to the control you always will need authentication and authorisation to read/open it again.

So is your goal to have access restricted files this on the control (always restricted) or on your PC?
