<div class="markdown_content"><p><em>Originally created by:</em> Captive Engineer</p> <p>Hi, JohnnyB.</p> <p>A couple years ago I was working on something similar in that I had an industrial PC running WinCC Flex runtime linked to a CoDeSys controller. I seem to recall that if you wanted Flex to grab symbol entries for populating a variable/tag/symbol list, it did in fact require a live OPC server, at least if you were bringing each symbol in "by hand."</p> <p>This seemed pretty tedious to me, so I wrote a Visual Basic script (for the PC, not for WinCC Flex) that parsed the OPC symbol file into a CSV file that Flex could then import. With over 400 symbols in that project (a lot for some people, a laugh for others), it saved me quite a bit of work.</p> <p>If this sounds like it could be a help to you, let me know and I'll try to unearth more details.</p> <p>Kind regards,<br/> The Captive Engineer</p></div>

<div class="markdown_content"><p>Simple question:<br/> Can OPC client (in my case WinCC flexible 2008) read/list symbol entries/variables of codesys program without being connected to PLC? I need a list of all tags created from symbol file to make a visualization. </p> <p>I'm using easy soft Codesys V2.3.5, Codesys OPC Server V2.3.9.5. Program is configured to work with Moeller XC-CPU101-C128K-8DI-6DO, but the problem is that I don't have access to any proper hardware at the moment.</p> <p>I tried many solutions, from generating <em>.sym and </em>.sdb files and inserting them manually to Gateway File folder, but I see the main problem in OPC configurator which requests PLC settings. Every time client tries to connect to OPC I get errors in log file like this:<br/> ERROR: Open communication to &lt;plc_single&gt; failed&lt;/plc_single&gt;</p> <p>I even tried to switch to multiPLC configuration to uncheck Active option (I don't get any errors) but relation server-client acts like in test mode (exception is that I don't get any item list).</p> <p>Please help!</p></div>
