<div class="markdown_content"><p>Hey,</p> <ol> <li>No, VisuUtils is designed in a way so that you dont have to call it from the VISU_TASK.</li> <li>You should be good using multiple instances.</li> <li>To be honest I only called it from a program, never from Execute ST-code. Cant give you an answer for this one.</li> </ol> <p>Best regards,<br/> Marcel</p></div>

<div class="markdown_content"><p>A couple questions about the use of FbOpenDialogExtended in the Visu Utils library:<br/> 1. Does it have to be called from the visualization task? It would seem to make sense, but in the example here: <a href="https://forge.codesys.com/prj/codesys-example/visu-dialog-st/home/Home/">https://forge.codesys.com/prj/codesys-example/visu-dialog-st/home/Home/</a> it's called from the main task.<br/> 2. Can there be multiple instances of this function block? For example, if I have several libraries, and they all use it, would it be better to put it into a GVL somewhere that they can all access the same instance? Or is it ok to declare it in different function blocks or libraries?<br/> 3. Does it take multiple scans to run? If I have it declared, say, in a GVL, should I be able to run it from the input configuration of a visu element ("Execute ST-Code")</p> <p>thanks</p></div>
