<div class="markdown_content"><p>Hello FabioPD,<br/> Before posting this idea, I tested it in a standard configuration and it works.<br/> What is a standard configuration, for me : <br/> - Periodic MainTask 20 ms calling PLC_PRG<br/> - Periodic VISU_TASK 100 ms<br/> - 3 visualization pages.<br/> - Tests in simulation mode and with CODESYS Soft PLC.<br/> - Target visualization and Web visualization.</p> <p>BR</p></div>

<div class="markdown_content"><p>Hello,<br/> If you want to knows each page change, you can write something like that :</p> <p>PROGRAM PLC_PRG<br/> VAR<br/> stMem_Page_Visu:STRING; (<em>To memorize the name of the last page</em>)<br/> iCompteur:INT; (Only to test th program<em>)<br/> END_VAR<br/> (</em>Program<em>)<br/> (</em>If the current page is different from the last page, you do what you want to do ...<em>)<br/> IF VisuElems.CURRENTVISU&lt;&gt;stMem_Page_Visu THEN<br/> iCompteur:=iCompteur+1; (In this example I add 1 in a counter</em>)<br/> END_IF</p> <p>...<br/> (<em>Here you can have some other parts of you program</em>)<br/> ...</p> <p>(<em>At the end, you memorize the name of the last page, in order to test it on the beginning of the program</em>)<br/> stMem_Page_Visu:=VisuElems.CURRENTVISU;</p> <p>I used the program PLC_PRG to test my idea, but you can use another program module name.<br/> BR</p></div>

<div class="markdown_content"><p>Hello <br/> I need to detect a page change in my project , I have a lot of pages and buttons that change page with a "change shown visualization" event. I know there is a sys variabile "VisuElems.CURRENTVISU" where I can see the current page , but i need to start a timer since the last page change and I need something that tell me if there was one page change.. or something that save the last VisuElems.CURRENTVISU value. I want precise that in my code i set VisuElems.CURRENTVISU for 3 pages/10.<br/> If you can help me will be appreciated. </p></div>
