Try using an Ethernet/IP scanner instead of an adapter, I'm guessing the 2 devices you're trying to communicate with are adapters, you have to have a scanner somewhere and Codesys should be a scanner. I don't know why you're getting the error, you should be able to use your Ethernet port as an EthernetIP adapter (although I've never had a reason to try,) but it's probably not what you wanted to do, unless you're connecting to another PLC that is a scanner. Good luck configuring the devices you're trying to connect to, it will be a lot easier if you have an .EDS file instead of starting with a generic module, even with an .EDS it can be tricky getting the communication working.

Post by nmcc on Viewing PDF in WebBrowser Visual Element ^{CODESYS Forge talk (Post)}
I am trying to show a PDF in a WebBrowser element. I have the file saved to the drive of the HMI/PLC. I am linking it in the URL parameter of the WebBrowser using the following directory link. 'http://localhost:8080/$$sdcard$$/FileName.pdf'. This allows for the program to download without any errors. When I navigate to that screen it is just a white box and nothing shows. I attempted putting the same link in the show parameter and I get a loading icon on my cursor when monitoring the HMI with my PC. Any help is appreciated. Thank you.

Post by tecnocons on Trouble Writing Files to External Paths in CODESYS ^{CODESYS Forge talk (Post)}
Hello everyone, I'm encountering an issue in CODESYS regarding writing files to external paths. Despite correctly configuring the placeholder in the CODESYSControl_User.cfg file to allow access to an external folder, CODESYS doesn't seem to write any files, and no errors are reported. The issue on the older versions was absent with no placeholders. I've checked the operating system permissions, and they seem to be in order, but the issue remains. Has anyone faced a similar situation or has any suggestions on how I might resolve this problem? Any help would be greatly appreciated. Thank you in advance for your support. I'm using raspberry PI as a logger. RPI3 Buster Codesys 32bit SL V4.11 Codesys Win64 3.5.20 [SysFile] PlaceholderFilePath.1=/home/pi/scan, $SCAN$

thank you very much! I found the generate_code methode, but struggled with the primary and active_application. With this expample I will be able to play around. If the code generation takes a minute or more I often switch to other programs and don't notify the process is finished. So now I'll get an alert and will switch back immediately. My next little project will be, to beep different if there are errors and a seperate script to do the download incl. the user management data base without stopping at the dialogs asking for onlinechange/complete download and overwriting an existing database and as goody, play a beep/sound again.

Post by stewnguth on New License not working. ^{CODESYS Forge talk (Post)}
Hey there, I am pretty new to the codesys space, but I got a codesys control basic M license for my raspberry pi that isntalled with no problem yesterday. Today, I went to install the visualization M locense as well because I went over the variable limit and am getting a "servernotfound" error in codesys when attempting to activate. I also tried to follow the advice in some other threads and install using a license request file on the web interface but am getting a message saying "An internal error occured" when attempting to install the license. Can anyone help me get this up and running? Thanks for your time.

Post by kronlundo on Licensing info not available (WAGO PFC200 + Codesys V3) ^{CODESYS Forge talk (Post)}
Hi! We're using a WAGO PFC200 for several projects towards the energy sector, and recently upgraded to CODESYS V3. We have the "IEC 60870-5-104 Server" package in a test program, and it works well with the package in DEMO mode. However, when we acquired a license for the "IEC 60870-5-104 Server" package and tried to add the license on the PFC200 through the license manager, we get an error (see attached file). It seems like there is no CmContainer on the device, does anyone have an idea on how to fix this? We've also contacted WAGO on this issue a while back with no feedback yet.

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
Hello, CODESYS Control is running on my RevPi, and my system communicates over a CANbus with a master using the ConnectCan module (Slave - CANopen Device). The communication works perfectly fine so far. However, as soon as I call a Python script with "SysProcessExecuteCommand2" that creates a CSV file and executes without errors, the master does not adopt any changes to the Transmission Process Data Objects (TPDOs). I don't quite understand what one has to do with the other, and perhaps someone can help me with this. Here is my script call: SysProcess.SysProcessExecuteCommand2(pszCommand:='python /home/pi/test.py', pszStdOut:=sCMDOutput, udiStdOutLen:= SIZEOF(sCMDOutput), pResult := ADR(eResult)); Thank you in advance! Best regards, Stefan

Hello, I have been using CODESYS for a while and after updating to version 3.5.18.50 the code randomly stops with this fault. Why is that ? I have tried to locate the fault in the Call Stack but I dont know what to do now... I have updated the projects properly for the version I am using. This fault started happening after like 14 days of using the new version of CODESYS.

However if I click "Scan Network" I can't find my controller. The only thing it finds is a "desktop" it seems (I'm using a Windows 10 on a Mac Book using VMWare, so maybe it has something to do with that?). How can I fix this? Thanks in advance!

Post by dom4u on Using PEAK CAN PCIe card (IPEH-004040) with Codesys Control RTE V3 ^{CODESYS Forge talk (Post)}
Some findings on this issue: PEAK CAN Driver is the same as in every PCI card from PEAK. I updated the inf file. Here are my steps: 1. Include right VendorID into the *.inf file 2. Disable Windows driver check (Disable WHQL check). This you need because 3S driver is not certified. You will find steps via google or ask chatgpt :) 3. Select: Select driver from a list and navigate to the folder. Say yes to install an uncertified driver. 4. Driver installed and device without errors I did the same with CAN Card from ESD, but here you dont need to include the vendor ID. In ANY CASE it was not successful. The RTIOwdmgeneric is not available in Codesys or anyhow accassable :( I wonder that it fails in two cases, two suppliers, two driver in the same way. How can RTIOwdmgeneric implemented into the project?

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Back in november I paused this, but wanted to reattempt using the persistent manager, the behavior is still the same. Most "login attempts" s are stopped with the message "One or more errors occurred" but I have no idea what that error might be. The only clue is this message is presented while the lower left status box says "Generating code...: relocation pou". For clarification. Build/Generate code is successful, no errors. Error appears when I try to download/login (physical or simulation) to a device. I did manage to login (in simulation mode) at one point, but then the error message "PersistenceChannel: Config file not found!". And no persistence files were created. I have done device-tree/reset-orgin also clean/clean all etc. Removed/re-inserted persistance manager. Behaviour is just the same. Removing Persistence Manage and everything is working OK. Is there possibly more info somewhere about the "One or more errors occured"-message?

Post by brubingh on Download Missing Libraries not working ^{CODESYS Forge talk (Post)}
We are working on a project and the customer required 3.5.16 BF4. After working on the project for a few weeks I opened it the next morning and it could not access libraries. IecVarAccess could not be accessed. I checked if windows updated - it did not. So no explanation for why it lost access other than that I shut down the computer for the night. Note that I am using a demo license. I still haven't figured out any reason to purchase a license. So I spent the next hour reinstalling CodeSys. Note that I did NOT uninstall first. After install I waited another 5 minutes for it to open the first time. I clicked File->Open to open the project. Previously I had selected File->Recent Projects - not sure if that makes and difference. But after this process it did open the project and compile it just fine. This is miserable. If this had happened when I went on site to a customer I would have lost hours of work doing the reinstall. Is there a different and quicker fix?

Post by leandroct on Error reading files after runtime update from 4.0.0.0 to 4.8.0.0 ^{CODESYS Forge talk (Post)}
Since version 19 they changed how file access is handle. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 The CodesysControl.cfg is at C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxPROJECT_NUMBERxx\ Here the email they sent me: "with the 3.5.19 Version we changed how files are handled. See following issue: CDS-81506 - CODESYS Control SysFile system file access vulnerability. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 Here is the official release-note: [[COMPATIBILITY_INFORMATION]] With the activation of ForceIecFilePath the file access from IEC is now restricted to the configured paths only (file sandbox)! [SysFile] ForceIecFilePath=1 (new default) The standard path is the current directory, the PlcLogic subfolder or a configured path. Every file access outside of this path is configured via PlaceholderFilePath, for example access to temporary files or removable media: [SysFile] PlaceholderFilePath.1=/tmp, $TMP$ PlaceholderFilePath.2=/media/usb, $USB$ PlaceholderFilePath.2.Volatile=1 For more information see our tutorial FilePath & Placeholders. To restore the old behavior ForceIecFilePath may be configured as follows: [SysFile] ForceIecFilePath=0 BUT WE HIGHLY RECOMMEND TO LEAVE THIS SETTING AT ITS NEW DEFAULT VALUE! "

Post by dekelec on Codesys 2.3 & Peak PCAN ^{CODESYS Forge talk (Post)}
I use Peak USB adapter daily to download from CoDeSys 2.3 and 3.5 to IFM, EPEC and other controllers. The process: - First you need to install the appropriate driver. Link: https://www.peak-system.com/Drivers.523.0.html?&L=1 - Restart the computer - Start the CoDeSys application - Change the name of the adapter in Communication parameters, as mentioned in previous comment. Write the name exactly as written "Peak_USB", as it could also be case sensitive (defines which .dll file to use). If this doesn't work I would contact the vendor of the controller to find out the procedure. In the attachment I've added a FAQ document from IFM regarding using PCAN USB. P.S. I've noticed in your picture of communication parameters a channel via TCP/IP is mentioned. In this case a USB to CAN connection is not being used. First you should change the channel/gateway to connect via CANbus or connect using an Ethernet cable.

Post by dominggus on FileDialog - OnDialogClosed not called anymore ^{CODESYS Forge talk (Post)}
Hi, since the latest update it seems the OnDialogClosed is not called anymore?? using CODESYS SP20 Patch 3 with CODESYS Visualization 4.6.0.0 I am using LoadWriteRecipe to load a recipe file from disk (with some custom dialog settings), and I need to run a function (Recipes_LoadFromRecipeData()) afterwards which I execute when OnDialogClosed is closed with OK button. See attached screenshot and code below: *** OnDialogClosed : Recipes_OnLoadFileDialogClosed(pClientData): *** // the DialogManager is provided via the implicitly available VisuManager dialogMan := VisuElems.g_VisuManager.GetDialogManager(); IF dialogMan <> 0 AND pClientData <> 0 THEN FileOpenCloseDialog := dialogMan.GetDialog('VisuDialogs.FileOpenSave'); // gets the FileOpenSave dialog IF FileOpenCloseDialog <> 0 THEN result := FileOpenCloseDialog.GetResult(); // gets the result (OK, Cancel) of the dialog IF result = VisuElems.Visu_DialogResult.OK THEN Recipes_LoadFromRecipeData(); END_IF END_IF END_IF *** OnMouseClick: Execute ST-Code *** // override FileOpenSave Dialog settings // Visu_FbFileListProvider.Initialize(stDirectory, stFilter, stFileIn, stTitle, iRowCount, bBrowseDirectory, bTouch) VisuDialogs.g_FileListProvider.Initialize('./', '*.bunkerrecipe', '', 'Load recipe', 20, TRUE, FALSE); VisuDialogs.g_FileListProvider(); This used to work in CODESYS v3.5 SP20 Patch 1, but it seems it doesn't work anymore unfortunately? The OnDialogClosed just never seems to be called anymore....

I connected my RPi to my company LAN and also my laptop to company LAN (using HP Docking station). This setup worked when I installed 'CODESYS Control for Raspberry PI', but now I donot know how to configure the gateway. Could anyone please help me in finding what I have to enter in the gateway configuration? Thanks, Vamsi.
