<div class="markdown_content"><p>Hello,</p> <p>does anyone else have some issues with Debug/Flow control and variables declared as VAR_IN_OUT (at least in FBD view and LD view) ?</p> <p>Declaration as follows:<br/> <span style="color: 85%;">FUNCTION_BLOCK TestFB<br/> VAR_INPUT<br/> Input1,Input2:BOOL;<br/> END_VAR<br/> VAR_OUTPUT<br/> Output1:BOOL;<br/> Output2:BOOL;<br/> END_VAR<br/> VAR<br/> DelayON,DelayOFF:TON;<br/> END_VAR<br/> VAR_IN_OUT<br/> IO_StartBit: BOOL;<br/> END_VAR<br/> </span></p> <p>In FBD view, it seems that the processed statements / variables are correctly displayed in a green Flow Control boxes, while the value of the variables itself remain ??? (Example in FBD_logic.png). </p> <p>In LD view the same logic displays the Flow Control boxes in a network up tu the VAR_IN_OUT variable as green and then they become gray, while the inside of the status of the VAR_IN_OUT variable is green (Example in LD_logic.png). All this goes against the description of how Flow Control in the help files...or maybe I'm missing something ? (This does not depend on the actual value of the VAR_IN_OUT variable.)</p> <p>The logical operations itself seem to be preformed correctly, just the Flow Control display seems wrong to say the least.</p> <p><img alt="IMG: FBD_Logic.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=510"/></p> <p><img alt="IMG: LD_Logic.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=511"/></p></div>
