<div class="markdown_content"><p>Thank you, Edwin for such a clear explanation!<br/> So as I understand we have several options to install libraries:<br/> 1. Install package file with libraries (e.g. Oscat)<br/> 2. Install library from "Library manager".</p> <p>And after library is installed we have to add it in project to use.<br/> Is it right?</p></div>

<div class="markdown_content"><p>Hello Dray,</p> <p>if the libraries are "grey" color this means they are inserted by either the plc-device(from the device description) or for example from a fieldbus master or<br/> any device in the device tree. <br/> If you need more information where the placeholder / resolution is done please open the plcaholder dialog.<br/> Here in this dialog you could even change the plcaeholder resolution if needed (this is mainly for testing purpose only - doubleclick on the middle row 'library' here you could change the Version for example)</p> <p>See also the powerful search line in the add library Dialog<br/> Just type what you know from your function and then click on the search result to add the library.</p> <p>Library in 'black' color are inserted by the user via add library (in my example Standard library)</p> <p>Then there is in some projects a second library Manager needed for example if you use Application Composer or even the visualisation libraries are availabe in the<br/> POU library manager.<br/> This is needed for these features in General I would add your libraries in the device tree library manager.<br/> Hope this helps.</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: Placeholder.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1900"/></p> <p><img alt="IMG: GoogleLibInfoandAddthelibrary.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1899"/></p> <p><img alt="IMG: LibraryManager.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1898"/></p></div>

<div class="markdown_content"><p>Hello,<br/> Can somebody explain the Codesys concept of libraries? What does it mean grey colour in Library Manager.<br/> I work with Berghof PLC and add Modbus Slave Ethernet device, but get 66 errors during Build process. It shows me that something wrong with "IODrvEthernet" library that is coloured grey. <br/> Where can I find this library?</p></div>
