Hi Guys,

I am very new to the whole Siemens PLC ecosystem. My project right now is to create a auto parking system with Password protection for the users. Right now I am stuck on how I can program the Password input function on the HMI using keypad. I am using TIA V14 SP1, ladder programming for this project. Picture attached for more information.

Steps:

1) Tap on password input box - keypad pops out - keys in desired 4 digit number - enter

2) Confirmation of password typed in

3) Where can I save the entered password in PLC ( I know it has to do with datablocks but uncertain)

Any experts in the forum to save me, much appreciated. Thank you.

better not save the password to the PLC, because it is not read/write protected. What kind of HMI are you using? - You can find login-functionality for all. When using a panel the user-password-list is stored encrypted on the panel.
