<div class="markdown_content"><p>Thanks, i-campbell.<br/> I've already tried the procedures i-campbell's link and worked well.</p> <p>But I think it is application authentication, not a user authentication. The reason is that when I checked UserTokenPolicy of the OPC UA server with UaExpert, I found UserPassword and Anonymous but couldn't find "X509 certificate" in the TokenType(Codesys_usertokenpolicy.png).<br/> So I couldn't connect with the certificate using UAExpert Authentication settings (Authentication_settings.png). The response message was "BadConfigurationError."<br/> On the other hand, when I connected to another OPC Server (Takebishi DeviceXplorer), "X509 certificate" appeared in the "UserTokenPolicy." (Takebishi_usertokenpolicy.png)</p> <p>I'm not sure this is the guide for user authentication, but I also tried user authentication with a certificate based on the following link, but it did not work.<br/> <a href="https://help.codesys.com/webapp/_cds_cmd_cyber_screen;product=codesys;version=3.5.15.0" rel="nofollow">https://help.codesys.com/webapp/_cds_cmd_cyber_screen;product=codesys;version=3.5.15.0</a></p></div>

<div class="markdown_content"><p>What?? No certificates are the preferred method. It is not in the FAQ, because it is not frequently asked.

<div class="markdown_content"><p>Hi,<br/> This Q&amp;A is very helpful to me.<br/> e.kislov's link says Codesys implements a user authentication with a password.<br/> I think that Codesys does not implement user authentication with X.509 certification so far. Am I right?<br/> My environment is Codesys V3.5 SP15 and raspberry pi</p></div>

<div class="markdown_content"><p>I'm investigating the same. Currently, the OPC server running in CODESYS V3 appears to allow any client to connect without authentication. They can then view the full tree, and read/write variables. This is very problematic. There are no options in the IDE that I can find for configuring the server, it is simply enabled in the Symbol Configuration. It appears the controller has an X.509 certificate but it doesn't require anything from the client. Does anyone have more information? The online videos from 3S worked to get me this far but they connected without authentication.</p></div>
