Post by imdatatas on Import from XML problem ^{CODESYS Forge talk (Post)}
Hello Everyone, When I try to import some POUs that were previously exported from another project as an XML file, I get an error like in attached image and the process does not complete. "There are no objects in the export file..." I am using SP21 Codesys IDE and I do not know which version this XML (*.export) file was previously exported with. Has anyone encountered the same problem? Regards, imdatatas

Post by nz-dave on Codesys 3.5.21 fails to copy file to USB ^{CODESYS Forge talk (Post)}
i had a similar problem trying to send files to C: on local computer. Ended up using Oscat ftp to transfer file with filezilla. i read there is an "write protection", possibly to do with windows, issue with sp19 and up. there are some config files in the codesys dir you can change, which may help. after i was able to transfer to local PC\downloads but not c: so went the ftp route. works well. https://forge.codesys.com/forge/talk/Runtime/thread/5cac1390b4/

Post by imdatatas on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic ^{CODESYS Forge talk (Post)}
Dear @gseidel, @tk096, I noticed that with SoftMotion V4.18.0.0, if a new axis is added to the project, the ramp type selection defaults to "Quadratic". In all previous versions, the velocity ramp type selection was "Trapezoidal". This causes some unexpected issues in projects with SoftMotion version V4.18.0.0 for newly created or newly added axes to existing projects. Is it possible to reconsider this situation in the next update and set the velocity ramp type to "Trapezoid" by default again? Best Regards, Imdat

Post by micky on Mail_Service_SL Lib ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe folgendes Problem. Ich möchte mit der Lib Mail_Service_SL ein Mail versenden. Manchmal funktioniert es auch aber nicht zuverlässig. Wenn ich den Funktionsblock sendmail mit den entsprechenden Daten aufrufe bekomme ich die Fehlermeldung CHECK_RESULT_FAILD. Laut Dokumentation sollte im sServerMessage der Grund stehen, dieser ist aber leer. Was kann der Grund hierfür sein? Gibt es eine ander Lib mit der ich Mails versenden kann? Viele Grüße Micky

I use this as follows:<fixed subdevicescollapsed="true">. But it seems it doesn`t work. I am ussing Codesys v3.5 SP16 Patch4. Is anything wrong with this? Or am I mistaken with the use of this attirbute?</fixed>

Post by mdetrana on VPLC Section 'Gray-ed Out' ^{CODESYS Forge talk (Post)}
When evaluating Codesys functionality, I found that the VPLC tab under Deploy Control SL > Operation > VPLCs is 'gray-ed out', see attached image. I'm trying to evaluate how my infrastructure will interact with Codesys on a Raspberry Pi 4, so I'm trying to demo running it. I was going through the Codesys tutorial here, and it never shows the tab as grey, so I do not know how to proceed. Let me know if I can get any additional information that can help.

There seem to be problems with the latest version of raspberry pi os 64bit (I used the lite version). The codesys control runtime crashes after a few seconds. The same runtime works on the raspberry pi image from 2023-10-10 When starting the runtime from the commandline, i get the following error: ooops... this runtime was build for RASPBERRYPI. Hardware version or firmware version not supported! (and yes, I'm running this on a raspberry pi :-)

Hello, I couldn't figure what/where the issue was, so I deleted everything from automation server and reinstalled the edge gateway and did the process again. It worked for about a month and then it stopped working again. It presents the same symptom, edge gateway is online but I can't connect to the PLC. Any idea of what could be the issue? Thank you!

Post by hsmw-wolf on How to fix Codesys Simulation Exception ? ^{CODESYS Forge talk (Post)}
Did anybody have a solution for this problem? I have the same issue and it occured as i wanted to continue work after the weekend. On Friday the simulation was working fine and on Monday thise error appears. There should be a more specific fault description to be honest. As I am writing I try to repair the installation and hope, that this will work. Still I am frustrated, because I don't know where to look for eliminating this fault. I am using CODESYS 3.5 SP19 Patch 5.

Folgendes passiert: Bild 1: Befehl in der Konsole eingegeben ohne sudo; Uhrzeit wird nicht gestellt (keine Berechtigung). Bild 2: Befehl mit sudo ausgeführt, Uhrzeit wird gestellt. Bild 3: Befehl ohne sudo von CoDeSys aus ausgeführt; Rückgabewert gibt die Uhrzeit an, die eingestellt werden sollte, Uhrzeit wird jedoch NICHT eingestellt. Haben Sie noch eine Idee was es sein könnte?

I'm getting this error on one of my projects. Searching for it I came across this https://www.codesys.com/fileadmin/data/Images/System/Releaseinformation/Patch-Note-CODESYS-Visualization-4300.html which says it was a bug VIS-1394, fixed in Visualization 4.3.0.0. I'm using a previous visu version, what is the cause of this error, and what can be done to work around it?

Post by frank2 on 3.5.17: Rezepte: Fehlendes Kontextmenü ^{CODESYS Forge talk (Post)}
Guten Tag, zuersteinmal vielen Dank fürs Lesen! Ich habe das Problem nun lösen können, indem ich %appdata%\CODESYS\UserOptions-EEEF5821 gelöscht habe. Dort gab es diverse Dateien names "CODESYS (CODESYS V3.5 SP17).opt.*". Nun funktioniert das Menü wieder so, wie es soll. Was ich mir sonst zerschossen habe, werde ich herausfinden. Aber ich denke, außer ein paar Einstellungen kann nicht viel passiert sein. Da ich das Gerät aber sowieso erst neu bekommen habe, ist hier noch nicht viel passiert. In diesem Sinne vielen Dank für die Aufmerksamkeit und ein schönes Wochenende Frank

Hi, jain. wir haben mit IFM gesprochen. Sie sagen es liegt an Codesys selbst. Die Daten seien anscheinend nicht konsistent wenn das Projekt zu und erneut geöffnet wird, sei ein probkem von SP11. IFM wird im Sommer ein neues Package rausgeben wo sie auf eine neue CS Version wechseln, dort soll das Problem dann behoben sein. Wir haben zwar einen Workaround rausgefunden aber jenachdem was du in der Safety treibst geht dieser dann nicht mehr. schreib mir zur not eine PN wenn du mehr wissen willst.

Post by wollvieh on Problem while updating to new runtime 4.11.0.0 ^{CODESYS Forge talk (Post)}
okay, no ideas. So i made a new fresh image for the raspberry, so far,so good. Licensing the new image was no problem. And, after having trouble while read write files on the raspberry pi, i found the solution for these file operations with the Variable ForceIecFilePath in the CODESYSControl.cfg file. Some people had that issue discussed in that thread : https://forge.codesys.com/forge/talk/Deutsch/thread/d2df08e587/

Post by wind-11 on Problem with simulation Modbus ^{CODESYS Forge talk (Post)}
Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by carohe on VisuNamespace != null ^{CODESYS Forge talk (Post)}
Hello, this error occured frequently over the past couple of weeks. I found out, when adding a webvisu, CODESYS added Visu libraries in the library manager. One of the libraries was the "VisuElemsAlarm" library. In my case it added this one with the version 4.3.0.0. However another library that also contained the "VisuElemsAlarm", used the "VisuElemsAlarm" with the version "4.4.0.0". After changing the Version "4.4.0.0" and uninstalling this version, the error has not occured anymore. Regards, carohe

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Okey, thank you! Do you think it is something in this library, that makes it possible to do the configuration in a PRG? https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/IoDrvEtherCAT.html#id1 I think the codesys modbus libraries support configuration and connection to modbus slaves without having to add the slave devices in the device tree. Just do it from function blocks inside the program. I was hoping for something similar with EtherCAT.

Post by food on Beaglebone Black OPC-UA Server ^{CODESYS Forge talk (Post)}
Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.

Post by rossanoparis on RevPi CONNECT+, CODESYS, EtherCAT master "Filedbus lost synchronicity" ^{CODESYS Forge talk (Post)}
Hello @rmaas I assume, you've already verified and tuned everything regarding the EtherCAT network. In my case the problem was due to a wrong core assignement. I suggest to not use the core #0 for your EtherCAT task. The OS realtime patch, which is present on RevPi OS, uses the core #0 for its porpouses and it mustn't be used by any other task which requires realtime and deterministic features. regards Rossano

Post by dkugler on Alarm State Icon ^{CODESYS Forge talk (Post)}
thank you for pointing me to this "bug"!! I haven't recognized, the bit is reset after the first alarm is gone. I use this only for warnings, so it's not a drama, but was not correct in the past. I solved it now simply stupid by counting up a variable every time an alarm appears and decreasing it if an alarm is gone. The "warning lamp" is activated by checking the counter is > 0 The nice side effect, i'm able to show the number of active alarms in the state line now.
