Post by thomasrohnerch on Color Change for Symbols not working ^{CODESYS Forge talk (Post)}
I have some Symbols from the Visualization Toolbox on my Target Visu on the Computer. I tried many Symbols, mainly Arrows. I'm able to control the visibility with condition e.g. "GVL.actual_testvalues.speed <= 0" But I can't do "Toggle color" with boolean GVL.b_toggle_color. Neither "TRUE" nor "FALSE" does change anything. Is this a known issue? I'm using CODESYS V3.5 SP19 Patch 5 + (64-bit). See attached file with more Version-Info. I'm currently using Style 6, Gradient axial 2, 3.5.12.0. I had the same issue with Default 3.5.16.0.

Post by imdatatas on Auto Declare window disappears by itself in the Ladder editor ^{CODESYS Forge talk (Post)}
Hello Everyone, The "Auto Declare" window disappears by itself in the Ladder editor. For example, a new function block is wanted to be added to the Ladder editor. (For example; MC_Jog block and instance name will be fbMcJog). To do this, "Empty box with EN/ENO" is added to the ladder line from the Toolbox on the right and when you type MC_Jog in the empty box and press enter, normally the "Auto Declare" window appears and you are expected to be asked to write the instance name here. However, this "Auto Declare" window closes itself immediately, it does not wait for the user to enter a value or close the window. I often encounter this situation in many IDE versions. Does this seem like a bug? If anyone has encountered a similar problem while creating a new program name, function or function block instance name regarding the "Auto Declare" window and knows a solution, I would be glad if you could share it. Best wishes Imdat

Update to Allura 1.12.0 ^{CODESYS Forge news (Blog Post)}
This night, we got an Update of Allura, the platform behind CODESYS Forge, to version 1.12.0. This version fixed a security issue in the global search. Before it was possible to see some of the private posts, sites or commit messages through the search. This is fixed now. Beside that the main improvement was in the field of "user mentions". I would say, that this feature became mature after this release. Not as part of the Allura update, but because of the CODESYS Forge upgrade, I enabled spell checking in the markdown editor. Have fun with it!

Post by nathant on Can't open online view of FB instance from code editor, only from Device/POU windows ^{CODESYS Forge talk (Post)}
Hello, The title pretty much says it all. When trying to open a FB from the CFC/Ladder/SFC editors while online, the FB does not open in an online view of that specific instance. Instead, it opens an offline view with '???' shown for the value of any variable. This makes debugging extremely cumbersome, as I have to find each FB in the POU window and select the specific instance I am trying to view. Anyone know the cause/solution for this? Thanks.

Post by dogulas on Removing a symbol from the IEC Symbols Editor grid ^{CODESYS Forge talk (Post)}
Right now when I make a change to one of the tags in my code, I have to completely remove the IEC Symbol Publishing object from the tree view and re-add it. Then I have to completely re-add every symbol to the grid view by dragging them over. This can be a lot. Surely, this is not the intended behavior. Can anyone tell me how this is supposed to work?

Post by dogulas on Removing a symbol from the IEC Symbols Editor grid ^{CODESYS Forge talk (Post)}
gatto, That works. Thanks. Typically I use my mouse more than my keyboard. That's why I was looking for a delete option from the right-click context menu or a delete button on a toolbar at the top. It never occured to me to use the keyboard. It might be a little more user friendly if they allowed a mouse wise ability to remove a line from the grid as well as the DEL key. Just a suggestion. Thanks for your help.

Build: CODESYS 3.5 SP19 Patch 1 (64-bit) Host OS: Windows 10 Target: Linux SL I have a project with programs in Structured Text and Ladder Diagram. When I try to use the Find function, it works for the Active Editor; however, when I try to use Find for the Entire Project, I get the error "Object reference not set to the instance of an object." I know what this error means in the context of the program, but I have no idea why the find function is returning this error. The variable I am searching does not matter: it happens with all variables. Any help with this will be greatly appreciated. I generally use the Find function quite often as I am developing and not having it is really slowing me down.

Ich hab noch etwas rausgefunden, falls jemand anderes noch ähnlich lustige Probleme hat. CoDeSys kann sich an der Windows UAC vorbeischleichen. Sprich man öffnet die CoDeSys IDE ohne Umweg über den CoDeSys Installer (in dem man gefragt wird ob man mit Administrator Rechten arbeiten will) und ist manchmal Admin. Deshalb kam ich nicht auf die Netzwerklaufwerke. Ich hab keine Ahnung warum das so ist. Abhilfe hab ich mir mit dem Registrykey geschaffen mit dem man auch als Admin auf Netzwerklaufwerke zugreifen darf.

Post by struccc on HTML5 Controls - string(>80) values ^{CODESYS Forge talk (Post)}
Dear all, does anyone have experience with HTML5 controls recently? CODESYS 3.5.20.30 / Visualization 4.6.0.0 I'd like to create a simple lightweight text editor, with proper multiline handling, cut & paste, scrolling, etc. And it seems to work fine, just have problems with strings longer than 80 bytes.... Declaring a variable sText1 : STRING(8000) and referencing it in the HTML5 Controls corresponding value property works perfectly one way: the code receive the data as a string (See log1)... (Note TypeID 1000...) Also sending back the data (seems to work (See log2) except it doesn't change the value of the bound variable. Probably the issue is with using SendSimpleValue method... Naturally, I could do a workaround, but maybe there is a more standard way to implement this... Please let me know if you have any suggestions.

Post by matthew on High resolution displays with 150% scaling causes CodeSys IDE to be blurry ^{CODESYS Forge talk (Post)}
I have just upgraded my laptop which has a high res display 2560x1600 and I have to have scaling switch on at 150% but everything looks blurry and not crisp, It seems CodeSys IDE is the only software on my system to look this bad, if I switch to 100% it's crisp but way to small. From a bit of research this could be due to the use of old windows forms or something? I have found a temp workaround that sort of works but not great. You have to run CodeSys in compatibility mode and adjust the DPI settings, this works ok and the editor is clear and crisp again but the actual tool bars are small like running at 100% Anyone got any tips for running CodeSys on high res displays with scaling?

Post by imdatatas on Programmatically change Tappet on a cam ^{CODESYS Forge talk (Post)}
Yes, There is. As explained "Manual creation of CAM structure" on below section. Likewise tappet structure also can be create manual and value of the switching point can be change during IEC program running. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_cam_programmatic_creation.html Just create a cam table and define some tapped points as sample for your project. Then on project compile, the created cam tapped data is converted internally into a global variable list. By clicking "Display generated code" in the "cam editor", you can display the automatically created global variables for both cam & tappets. Regards, Imdat
