<div class="markdown_content"><p>Now, for CODESYS v3.5 SP21 I can no longer find the "OPC UA Information Model Repository" entry to add as a command. In the "Tools" menu it is listed but greyed out, reporting "Plug-in is not available". So how do I add the Plug-in?</p></div>

<div class="markdown_content"><p>Ah, I think I figured it out.<br/> I added a Command through "Customize":<br/> <img src="./attachment/customize.png" width="50%"/></p> <p>Now I find and can open the OPC UA Information Model Repository tool, allright.<br/> However, I get an error respons when trying to import a nodeset file for the ProfiNetEnergyMeter.<br/> I will have to look into whether this nodeset is the actual model to be imported or not. Maybe not....</p></div>

<div class="markdown_content"><p>I can not find the OPC UA Information Model Repository tool.<br/> My device is the CODESYS Control Win x64.<br/> I have (what I believe is) plain vanilla Codesys v3.5. SP18 installed.<br/> Also I have SBC QronoX ECS, a Codesys knock-off that is also based on 3.5.18.0, but it should be completely separate installations.<br/> According to Online Help one is to find the OPC Information Model Repository under toolbar menu "Tools":<br/> <img src="./attachment/help.png" width="50%"/><br/> My Tools menu opnlu has this:<br/> <img src="./attachment/tool.png" width="50%"/></p> <p>So, am I blind?<br/> Also, the "CODESYS Installer" tool does not open. Maybe it is related?<br/> Does the CODESYS Control Win x64 not provide a OPC UA server?</p></div>
