<div class="markdown_content"><p>Hi all<br/> I am using a schneider m262 plc that is programmed with ecostruxure 1.2 (based on codesys 3.5.12)<br/> In this plc when the IDE connects online, the user and password are asked.<br/> First time i need inpunt Administrator , Administrator and after I am invited to change password.<br/> From now on, online access requires Administrator and the password I have chosen.<br/> When I am online I see below the access as Administrator.<br/> This is good for plc security.<br/> But with these settings, an hmi (not schneider) cannot read the variables set in symbol configuration !!!!!!</p> <p>So I need to enter inside the plc web server configuration and disable the users.<br/> From now on, online access with the IDE no longer requires a password and at the bottom I see access as Anonymous.<br/> From this moment the hmi can read the variables !!!!!</p> <p>Can anyone explain to me what users and passwords are for.<br/> I would :<br/> Set <strong>rules that only the variable zone can be accessed without a user and password.</strong> like Anonymous now.<br/> And keep user and password for changing / downloading the program with the IDE.<br/> Thanks.</p></div>
