<div class="markdown_content"><p>hm..<br/> could you confirm that the miniproject from</p> <p>"c:\Users\&lt;windowsusername&gt;\CODESYS Control for Raspberry PI\3.5.9.X\Examples\OPCUA.project" &lt;/windowsusername&gt;</p> <p>works with your configuration and changed /etc/init.d/codesyscontrol (added the sleep 10 in that file in the <strong>do_start</strong> section)</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi Folks,<br/> Ive tried all of these hacks pertaining to opcua, pi config files, and restart codesys engine etc, and Im not having reliable repeatable success. Have there been any further developments or guidelines re getting OPCUA server to work on Raspberry pi 1.3.0.0 with CoDeSys v3.5.9.2 runtime ? We use unified-automation OPCUA SDK internally in the office for other stuff, and are familiar with opcua. But troubleshooting it on codesys pi is difficult. Im trying to thrash out a major use case / proof of concept for abstract control system development for our biggest client, so any help much appreciated. I got it to work once, then couldnt repeat it. Is there anything obviously wrong with the symbol configuration below? Im getting the raspberry pi empty config on ua expert, but not any variables that are supposedly configured to be available via opcua.<br/> thanks<br/> Cormac</p> <p><img alt="IMG: TheViewFromUAExpert.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2187"/></p> <p><img alt="IMG: TheViewSymbolConfigurationt.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=2186"/></p></div>
