Post by noah on "Invalid Value" for Variables at Runtime ^{CODESYS Forge talk (Post)}
Hello, I also have the problem that suddenly all variables in my project were invalid and shown as "???" during runtime. Could you manage to fix the problem in the last 4,5 years ;) ? Because I tried everythin to fix it but nothing worked. I feel like maybe this is a bug. Thank you.

Escape character behavior for hex values in string -- what gives? ^{CODESYS Forge talk (Thread)}
Escape character behavior for hex values in string -- what gives?
Last updated: 2026-03-09

Post by gordonkeller360 on Escape character behavior for hex values in string -- what gives? ^{CODESYS Forge talk (Post)}
I have a program which sequentially places byte representations of characters from a string into an array. FUNCTION_BLOCK MoveBytesFromString VAR_IN_OUT abRxBuf: ARRAY [0..79] OF BYTE; END_VAR VAR testString : STRING := '$0A$R$L$TTesting,123...$94$86$0A'; iCount: DINT; END_VAR ---------------------------------------------------------------------------------------- // clear the buffer MEM.MemFill(ADR(abRxBuf), 80, 0); FOR iCount := 0 TO LEN(testString) - 1 DO // account for undesired null terminator of string abRxBuf[iCount] := testString[iCount]; END_FOR Escaped characters, like $T, $N, etc. work just fine, and so do their hex representation counterparts ($09, $0A, etc). However, when I put something like $94, I get a set of nonsense values... see image attached after one spin of the program. Could someone explain to me what is happening here? I'll continue to investigate...

To shutdown the TargetVisu: Add the VisuElemBase library to your project then call VisuElemBase.Visu_PRG.RemoveAllTargetVisuClients(); Exemple: PROGRAM PLC_PRG VAR xShutdownTargetVisu: BOOL; END_VAR ---------------------------------- IF xShutdownTargetVisu THEN xShutdownTargetVisu := FALSE; VisuElemBase.Visu_PRG.RemoveAllTargetVisuClients(); END_IF I tried calling RemoveAllTargetVisuClients() directly from a button mouse click event but it makes the Visu crash. So better using the code above and just set xShutdownTargetVisu to TRUE from the button. Works fine for me. To start the TargetVisu: From a cmd prompt. This will start the TargetVisu C:\Program Files\CODESYS\CODESYS Control RTE3>VisualClientController.exe --application=Application --flags=1 You can then place a .bat file on the desktop and put this inside: CD "C:\Program Files\CODESYS\CODESYS Control RTE3" VisualClientController.exe --application=Application --flags=1 exit Double clicking the .bat file will start the TargetVisu. You may need to replace the Application name by your own application name. Good to know: In the cmd above, if you replace --flags=1 by --flags=2, it will shutdown the TargetVisu.

To change the color of search result markings (the "find color") in the CODESYS Text Editor using Themes, follow these steps: Go to the menu: Tools → Options. In the Options dialog, select the Text editor category. Switch to the Theme tab. Here, you can select your desired color theme for the text editor. The available color schemes (themes) are stored in the installation directory in the Themes folder. To specifically adjust the color for search result markings, go to the Text Area tab within the Text editor options. Here, you can customize the Selection color – Inactive parameter, which determines the color used to highlight search results. Changing the theme will apply a new set of color settings, including those for selections and search highlights. If you want further customization, you can manually edit or create your own theme files in the Themes folder of your installation directory Example "c:\Program Files\CODESYS 3.5.21.50\CODESYS\Themes\myDefault.editortheme" https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_options_text_editor.html

Hi -- Did you have any luck porting this over to RTE? I have a similar situation, where I am using CAA SerialCom and it works fine with Control Win, but I can't open the port when using in RTE. Any advice helps. Thanks!
