Hi all
I am using a schneider m262 plc that is programmed with ecostruxure 1.2 (based on codesys 3.5.12)
In this plc when the IDE connects online, the user and password are asked.
First time i need inpunt Administrator , Administrator and after I am invited to change password.
From now on, online access requires Administrator and the password I have chosen.
When I am online I see below the access as Administrator.
This is good for plc security.
But with these settings, an hmi (not schneider) cannot read the variables set in symbol configuration !!!!!!

So I need to enter inside the plc web server configuration and disable the users.
From now on, online access with the IDE no longer requires a password and at the bottom I see access as Anonymous.
From this moment the hmi can read the variables !!!!!

Can anyone explain to me what users and passwords are for.
I would :
Set rules that only the variable zone can be accessed without a user and password. like Anonymous now.
And keep user and password for changing / downloading the program with the IDE.
Thanks.
