Blocking ladder execution with Passwords

[Marcelo]

Hello, Im having some issues to do this task on unilogic. Will thank any help you could give me. 

I need to block the screen and the  execution of the program every  month for a full year and the only way to unlock this is filling a Password wich has to be diferent for each month.

Tried to make this work with RTC.Date blocks but its a very long codding and the idea its to make it as simple as possible to avoid slowing the program execution. 

Thanks in advance.

Ausman find ladderart solution in Visilogic ladder subroutine that can be imported to blank project.

You can implement the same idea for your project in Unilogic
