TD PASSWORD

Talk of the 0BA8 and the Logo! TDE?

Then it is possible to assign for the change from the operator in the administrator mode password, which can consist of letters or numbers.

But the complete TDE means of a password can not be locked.

From manual 11/2009

● An additional password protection function is available in the LOGO! TD (version ES4 or
later) and can only be enabled when the LOGO! TD is used together with a LOGO! Base
Module (version ES4 or later).

from RUN mode to STOP mode from the LOGO! TD. You can not stop the execution of the
circuit program in LOGO! from the LOGO! TD without entering the password.

least ES4

There is only one password that you can assign for LOGO!. You can only assign it from the

I have now read the manual extent that the TD will not be locked with a password.
Only the program in the logo, and the stop / start on the TD can be protected with a password.
The password can can have up to 10 characters contain uppercase characters.

 You are right and I think it's enough for this type of PLC.

Thank you ixo65 for your research, i didnt think it was possible.

I have already installed the device in the clients orchard and he was happy with having a combination of buttons to block certain funcions.

P.S

Thanks for the spanish manual it was a nice detail but as you might have noticed by my name im english i just work in spain for a siemens solution partner but i thought it was a kind gesture, thanks again
