<div class="markdown_content"><p>Hello,<br/> Codesys IDE is 3.5.21.30<br/> IoDrvBase is: 3.5.17.8</p> <p>I am working on implementing Codesys on our I/O product line, using the IO driver examples, and the Linux UDS socket approach.<br/> I have sucessfully created an implemetation where I have a Device with mutiple slots, on which I can plug modules. These modules represent our IO modules, and communication is successful.<br/> (For this question the assumtion can be made that Codesys commucates with 1 'master' device, which handles further communcation with the IO modules. For the next part of the question it can be <br/> assumed that the Master device has a list of which modules are attached/available)</p> <p>I'm now trying to implement the 'Scan for Devices...' feature, but I'm completetly lost on what to do once the IoDrvScanModules method is called in my IoDrvFB.<br/> I'm guessing that the ppConnectorList has to be filled with the found devices, but I have no idea if that is the correct approach. And Codesys is not triggering my breakpoints in the method, which makes things more difficult.</p> <p>I hope someone could provide some examples or guidance on what steps I should take to implement the scan feature.</p> <p>Thanks in advance.</p></div>
