Post by jasperclauwaert on Persistent Retain Variables Not Visible in Online View (WAGO PFC100 + CODESYS) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m working on a WAGO PFC100 with CODESYS. During development everything worked fine, but in the final stage I set several variables to PERSISTENT RETAIN. When I go online, most of these persistent variables cannot be monitored. Instead, I see: <Value of the expression cannot be retrieved> Interestingly, a few variables do show their values correctly, but the majority do not. The variables are not used as pointers or in any unusual way. The application compiles and runs without errors. Has anyone experienced this before? Is this a known issue with PFC100 or CODESYS? Any ideas on what could cause this behavior? Thanks in advance! Jasper

Good night. I am having a problem with CODESYS 3.5.11.40, which gives the exception EXCEPTION [ProcessorLoadWatchdog]. I followed some forum posts and tried to modify the CODESYSControl.cfg file, but it shows: [SysFile] Windows.WorkingDirectory=C:\ProgramData\CODESYS\CODESYSControlWinV3\D5050FE1 Then I go to this directory and try to modify CODESYSControl.cfg according to the forums, but it doesn’t work: [CmpSchedule] ;EnableLogger=0 ProcessorLoad.Maximum=80 ;Timeslicing.Mode=Internal ;Timeslicing.PlcSlicePercent=80 ;Timeslicing.PlcSliceUs=4000 ;Timeslicing.StartOnProcessorLoad=1 ;SchedulerPriority=5 ;SchedulerInterval=1000 I tried to change ProcessorLoad.Maximum to 0 or 100, but it doesn’t compile when I try. I really don’t know what to do,

Post by forklift on Anfänger hat Problem ^{CODESYS Forge talk (Post)}
Hallo, ich bin Anfänger mit Codesys und Programm in ST. Wir haben FTS-Fahrzeuge die mit einer Wago-Steuerung ausgerüstet sind. Dies wurde von einer Firma vor Jahren programmiert. Die Firma ist nicht mehr erreichbar und nun sollen wir als Instandhalter diese FTS´en mit betreuen. Da wir aber nur Siemens benutzen(TIA, S7 und S5) haben wir keine Ahnung von der Steuerung. Ich wollte eigentlich nur Online gehen aber Codesys übersetzt das Offline Prg. und meckert das die nicht in Ordnung ist. Das Offline-Prg. ist das Original-Prg. villeicht könnt ihr mir weiter helfen Bild s. Anhang

Post by imdatatas on Codesys IDE initialization error from a new Sandbox image ^{CODESYS Forge talk (Post)}
Hello everyone, I created a new sandbox image on the D drive with Codesys Installer. However, when I launch the IDE from this image, it gives the error shown in the attached image. -- Codesys V3.5 SP19 Patch7. -- The installer is the latest (2.5.0). -- All packages in the installer were updated to the latest version as of today when creating the sandbox. -- The originally installed IDE on the C drive does not give this error when launched. -- I last upgraded it to Softmotion 4.20.1.0 through the installer. Has anyone encountered the same or a similar issue? Will this issue be fixed in the next update? Best regards, Imdat

Post by timvh on Version management ^{CODESYS Forge talk (Post)}
This depends on what you want to achieve with installing the latest version and how you manage your projects and repositories. Maybe you also want to update your device (right click on it to update) or maybe your device is depending on certain versions of libraries (go to the library manager in your project and download the missing libraries). An option is also to first create a projectarchive of the current project you have before you install a new version of CODESYS. Then you can open this projectarchive in the new CODESYS version. Especially if you install the latest version of CODESYS in a Sandbox.
