Hi there

I'm working on Sinumerik 840D with step7.
The aim is to not have to write manually the password SU****E (the passwordfor the level 1)but to do it automatically when we click on button, we want to do that thanks to the function LOGIN of the FB4, with DB260. And then we disconnect thanks to another pushbutton and the function LOGOUT.

The disconnection works but we have some trouble for the connection, when we push the button nothing occurs.
I set the password in a DB and program FB like the picturein attachment.

Ifound a block descritprion but it doesn't help a lot so I want to know if somebody can help me about the procedure more precise than the descriptoinand how to use this function. Does anyone have an example?

Thank you

Have a nice day
