<div class="markdown_content"><p>Instead of using global variables, try adding the variables directly into the button by using PLC_PRG.variablename. Maybe this makes a difference.</p> <p><a href="https://imgur.com/EBkUbHG" rel="nofollow">https://imgur.com/EBkUbHG</a></p> <p>In this example I've added the variable BUTTON_PRESS to my PLC_PRG.</p></div>

<div class="markdown_content"><p>Hello,</p> <p>it seems a very simple problem but I have been searching for long time for a solution.<br/> I'm using Codesys V2.3 as beeing installed by the ABB Automation Builder. I'm using an ABB PM554ETH PLC.</p> <p>I created a very simple PLC_VISU made of a button and a rectangle.<br/> The button is associated to a global variable (BOOL) that, in a CFC program, goes directly to another global variable (BOOL) associated with a color change of the rectangle.</p> <p>The webserver is properly configured. I download everything on the PLC and run. From the simulation tab (in Codesys) everything works as expected: 1 click on the button (that stays pressed) changes the color of the rectangle. Another click returns the button up and the rectangle is restored to its original color.<br/> If I try to access to the webvisu.htm using Internet Explorer (correct Java version with safety exceptions configured) I can see the correct interface (button + rectangle) and the status of the items is following the situation we have in the simulation environment (for example button pressed and light on).<br/> If I try to interact from the webpage, after clicking on the button, it immediately returns up and the status of he rectangle is never changed. I tried inserting in the interface also a simple slider and the effect is the same: I can move the cursor by one click only and then it returns in the center, unless I move it from the simulation and the webpage shows its new position.<br/> If I insert also other objects that must show the value of a variable, they work fine. My problem is on the INPUT only.</p> <p>Am I missing something fundamental to get this working?<br/> I tried analyzing many videos on the web but I see that in all the cases I found, what can be done in simulation (regarding button press) should be possible also by the webpage.</p> <p>Thanks for your support.<br/> Regards,<br/> Alessandro</p></div>
