<div class="markdown_content"><p>Hi,</p> <p>this is only possible with a setting:</p> <p>in webvisu.cfg.json in /visu <strong>"NumCachedImages": 0</strong> </p> <p>Code:</p> <p>{<br/> "UpdateRate": 200,<br/> "PlcAddress": "0000.9ED4.C1D5",<br/> "UseLocalHost": true,<br/> "Application": "Application",<br/> "StartVisu": "SendTweetVisu",<br/> "NumCachedImages": 0,<br/> "BestFit": true,<br/> "LogLevel": "INFO",<br/> "CommBufferSize": 50000,<br/> "HasKeyboard": false<br/> }</p> <p>Then you need to take care that CODESYS doen not overwrite webvisu.cfg.json on every download - make it readonly or change the name in CODESYS to webvisu_my in CODESYS.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hello,</p> <p>I am looking for a way to change an image live on the file system and have it updated on the target/web visu.<br/> It seems that once the runtime has loaded, it will always display a cached version of the image on the targetvisu.<br/> I have tried unregistering/registering the file, but it does not seems to do anything.</p> <div class="codehilite"><pre><span></span><span class="n">BmpPoolUnRegister</span><span class="p">(</span><span class="n">IMAGE_POOL_ID</span><span class="p">);</span> <span class="n">BmpPoolRegister</span><span class="p">(</span><span class="n">szFile</span> <span class="p">:</span><span class="o">=</span> <span class="n">IMAGE_FILE_LOCATION</span><span class="p">,</span> <span class="n">szId</span> <span class="p">:</span><span class="o">=</span> <span class="n">IMAGE_POOL_ID</span><span class="p">);</span> </pre></div> <p>I have also tried registering a new file under a new ID without any luck.<br/> Changing the page does not help either.</p> <p>Is there a way to do this without restarting the runtime in 3.5.4.x?</p> <p>Thanks!</p></div>
