Post by mondinmr on Unexpected behavior in cyclic encoder read method during INT overflow (wrap-around) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m investigating a potential issue with a cyclic method we use for reading incremental encoders in our libraries. I’ve come across two implementations that, at first glance, appear to perform the same operation: motionUnit.vlPositionActualValue is UINT due strange encoder type. Version A METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; rI: INT; delta: INT; END_VAR rI := TO_INT(motionUnit.vlPositionActualValue); delta := rI - actPosFieldOld; m_actPosRaw := m_actPosRaw + TO_LREAL(delta); actPosFieldOld := rI; IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Version B METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; END_VAR m_actPosRaw := m_actPosRaw + TO_LREAL(TO_INT(motionUnit.vlPositionActualValue) - actPosFieldOld); actPosFieldOld := TO_INT(motionUnit.vlPositionActualValue); IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Both use INT and the same delta logic, so they seem equivalent. However, when an overflow (wrap-around) occurs, version A continues correctly as expected, while version B unexpectedly resets to -32768 without a clear reason. Has anyone experienced similar behavior or can shed light on what might be happening here? It almost seems as if the cast to LREAL is being applied before the calculation — but that would be illogical and potentially very dangerous in many situations! Thanks!

Post by sbhaskarla on WebVisu File Transfer Error ^{CODESYS Forge talk (Post)}
I’m encountering an issue when downloading CSV files via the WebVisu button input config -> file-transfer option: • Custom directory: /plcdata/csv_logs/filename.csv o Error: Error 4 – Error during file transfer • Sandbox directory: /var/opt/codesys/PlcLogic/plcdata/csv_logs/filename.csv o Result: Download succeeds without error. Actions taken so far: 1. Added /plcdata/csv_logs to codesyscontrol.cfg (see attached). 2. Enabled file-transfer services in codesyscontrol_user.cfg (see attached). 3. Confirmed that the PLC writes CSV files correctly to /plcdata/csv_logs/. Despite these settings, WebVisu still returns Error when accessing the custom path 1. Using the placeholder file path '$$CSVLOGS$$/filename.csv' and it returns Error 6. 2. Using the literal path /plcdata/csv_logs/filename.csv and it returns Error 4 Could someone please help me determine what additional configuration or troubleshooting steps are required to serve files from /plcdata/csv_logs/? Please find screenshots attached for better understanding and I have also attached the config files

Post by erictur on CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC ^{CODESYS Forge talk (Post)}
UC3100 comes with Arm Cortex-A8 1 GHz and belongs to Moxa Industrial Linux 1 (Debian 9) for Arm-based Computers. I tried to install the CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC. Unfortunately, the Third-party requirements: - libc >= 2.27 (required by CodeMeter Runtime) of the CODESYS Control for Linux ARM SL cannot be met on the Debian 9, which comes with glibc 2.24. I read the post by @johnlee (Getting Start with Codesys Control for Linux SL) (https://forge.codesys.com/forge/talk/Runtime/thread/0a515ced3f/). Where he discusses installation of CODESYS Control for Linux ARM SL on Debian 9. There was CODESYS Linux runtime v3.5.14 availble and it was successfully intalled on the Debian 9. However, the CODESYS Store has the oldest version V4.1.0.0 32 bit available. There is no way to find the CODESYS Linux runtime v3.5.14. So is there any work around for this? Or I cannot install the CODESYS Runtime on any of the Moxa IPCs based on the Moxa Industrial Linux 1 (Debian 9)?

Post by timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To get the current visu for all your individual web clients, you could iterate over them, using the same library 1) Create a new function block which implements VU.IVisualizationClientIteration 2) Create an instance of this function block + add an instance of the "iterate" function block fbIterateCallBack : FB_IterateOverClients; // this implements VU.IVisualizationClientIteration fbVuIterate : VU.FbIterateClients; // this FB iterates over all clients 3) Call the fbVuIterate and set the reference to the call back FB. Then it will automatically call the method "HandleClient" of this function block. fbVuIterate( xExecute:= NOT fbVuIterate.xDone, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, eError=> , itfIterationCallback:= fbIterateCallBack); In the HandleClients method you can use the property of the interface of your webclient to which page it is currently on: sCurrentVisuOfClient := itfClient.CurrentVisuName; 4) Optionally from here you could also set the visu for the webclient, but this might be obsolete, because the other function block is now available... xQueryOK : BOOL; xChangePage : BOOL; itfVisuClientRawData : VU.IVisualizationClientRaw; xQueryOK := __QUERYINTERFACE(itfClient, itfVisuClientRawData); IF xQueryOK AND xChangePage THEN VisuElems.g_VisuManager.SetMainVisu(pClientData := itfVisuClientRawData.ClientDataPointer, stVisu := 'Visu2'); xChangePage := FALSE; END_IF

Post by pernockham on AC Persistence - values are not read from file during start? ^{CODESYS Forge talk (Post)}
Im struggling with the AC Persistence. AC persistence seems to work for any variable that is changed online and values are kept during reboot. However, if I try to edit the persistence files offline or replace the persistence files with a previously downloaded older persistence file (with modified values), the online value will not follow, as if the system did not at all read the file at boot? My testing sequence. - Edit a the value of a persistenced variable (with xSaveOnChange = True) - Save/download the associated persistence file, (and confirm the value has changed). - Edit the value online for a second time . - Stop runtime - Replace (upload) the persistence file with my previously downloaded file . - Coldstart/Warmstart/Start runtime - Whatever Im trying the value of my persistence variable will always be equal to that of my second edit as if the file is not read/considered during boot. What am I doing wrong?

Post by leandroct on Creating Boot Application not working ^{CODESYS Forge talk (Post)}
I have a Control Win V3.5 SP20 (64-bit) application, and until now, I open the program (with a password) and download it. However, I need to give the client the option to install the program on the Controller, without them having to open it and access the code. So, I followed these steps: 1 – In the Online => Create Boot Application menu, I saved the generated files in a directory: Application.app Application.crc PlcLogic\visu\ directory with several files 2 – In the SysTray, I ran the PLC, and it created a directory. In the root of this directory (C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E84889DB), I pasted Application.app and Application.crc. Since it created a \visu directory, I pasted the PlcLogic\visu\ files generated in Create Boot Application into it. 3 - In the general Codesys directory (C:\ProgramData\CODESYS\CODESYSControlWinV3x64), I edited CodesysControl.cfg, adding: [CmpLog] Application.1=Application 4 - When running the PLC, nothing happens and the TargetVisu screen does not open. What I'm doing wrong?

Post by gseidel on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
Hi SLUCodesys, dwErrorId is a drive specific error number. The drive documentation should be consulted to interpret it. (Note that you should use MC_ReadAxisError to read this error, see https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/MC_ReadAxisError.html. Accessing the internal variable will result in outdated values if the acis error is not mapped by PDO and is not recommended in general.) uiDriveInterfaceError holds errors of the SoftMotion driver for the drive. It is also an internal variable, not intended for direct access. It is intended for logging, the PLC log will contain the drive interface error, consisting of this number and an error text. My recommendation for handling axis errors in the CODESYS application: 1) Use MC_ReadStatus on the axis to find out whether it is in state Errorstop 2) If in Errorstop, there are two possibilities: an error reported by the drive (MC_ReadAxisError) or an error of the SoftMotion function blocks (output MC_ReadStatus.FBErrorOccured). 3) If there is no drive error, you can use SMC_ReadFBError https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/FBError/SMC_ReadFBError.html Best regards, Georg

Post by nicetuxedo on Can not activate license on Raspberry pi ^{CODESYS Forge talk (Post)}
Hello everyone, I'm hoping for some assistance with a license activation issue: a software crash has left my license in a strange state. Here is the sequence of events: I purchased a new license for the Raspberry PI from the official CODESYS web store. I opened the CODESYS and started the online activation process using the ticket number I received. During the activation, the CODESYS software threw an exception and crashed. I was not able to see if the activation completed. After restarting CODESYS, I attempted to run the activation process again with the same ticket number. The License Manager now gives me an error stating that the ticket has already been activated/used. I am now stuck because my installation is not licensed, but the activation server believes my ticket has been consumed. Has anyone encountered this before? Is there a way to have the ticket status reset?

Post by thewizard8 on Raspberry PI4 Serial Port ^{CODESYS Forge talk (Post)}
Hi Dear All, I'm using my raspberry PI4 as a CoDeSyS PLC (Build from scratch with custom electronics). I was able to implement all fieldbuses with the exception of Modbus Serial. I'm using the internal Port (GPIO) and I configured it in /etc/Codesyscontrol_user.cfg the following away: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 Linux.Devicefile.2=/dev/ttyS0 I'm using COM2 on Master configuration. I'm using a interface board from TTL/RS485 (bidirectional board), and it's works perfectly with other devices but not in CoDeSyS. I'm able to send data with python script and read it on my pc using putty, but when I use a modbus slave simulator to interface with codesys I always get red icons on master and slave. (Please find image attached). I'm pretty shure that this might be a bad parameter on my CoDeSyS runtime configurstion file. Can someone help me? I'm stuck and this is for my master degree certification.

Post by k2saki on CNC / G01 Speed is very slow (or go-stop motion) in Continuous short segment . ^{CODESYS Forge talk (Post)}
I'm using CAD/CAM that outputs GCode with G01 many short segments from NURBS Curve, only X-Y axis. But CODESYS CNC motion seems much slower ( or stop-go motion ) in simulation mode than F-Value (I checked value from SMC_Interpolator - dVel ). In GCode G01, F value is F500, but movement is very slow, actual speed (dVel) is between 0 to 30 back and forth. I think very old CNC can move like that, but nowadays, a lot of CNC can move smoothly to process free curve ( somethimes option switch ) I tried to use G51 Dxx but I got the same result. My questions are 1) How do I improve CODESYS CNC motion in this case ? 2) How can I graph the sampling from dVel of SMC_Interpolate in CODESYS?

Post by fizzy-bubblech on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Colleagues, i have the same problems. At the current time, I have to use the new version of the Codesys (3.5.20.10) + Control for Linux SL 4.11.0.0, but it works unstable : theree are a lot of freezes and not-respondings. I tested this on different projects: those that were created in the current version of the project, and those that were migrated from other versions of the development environment. Compiling a project without connecting to a controller is fast enough. The first downloading of the code into the controller, too. But as soon as you need to make edits and download a new code problems begin. Codesys "freezes" at the "Generation code" stage for 15-20 minutes. And only after that time loads the code into the controller. Previously, we used version 3.5.17.60 + Control for Linux SL 4.7.0.0. The process took 1-2 minutes. Do you have any ideas how can i fix it? I will be grateful for your answers.

The acute accent character is used for backticks: ´ (Unicode: U+02CA) The use of backticks is recommended in order to be able to use the same identifiers in CODESYS as in other programming languages or documents, such as circuit diagrams. Any character may be used between two backticks, except line breaks and other backticks. Keywords are also allowed as identifiers between backticks. Examples: ´Variable+9´ ´INT´ The backticks are part of each identifier and therefore var1 and ´var1´ are two different identifiers.

Post by thn-power on Updating OPC UA Core Nodeset on PLS ^{CODESYS Forge talk (Post)}
Hi After much trail and error I think I found the root cause to my OPC UA problem. The problem is that I cannot manage to build and download a program with a a custom OPC UA Information model. We use a Weidmueller WL2000 PLS, but the problem also exsist on the Win V3 PLC. Our custom information model is based on the latest versions of the OPC UA Core Nodeset v 1.05.03 (2023-09-20) and UA/DI nodeset 1.04.0 (2022-11-03) Those nodesets are installed in the Codesys Information Model Repository (3.5.19.6) However, when trying to build I get the following error. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://bos.org/ with a minimal publication date from 15.12.2023 but the device has only a model from 15.09.2021 installed. Probably the information model from 15.09.2021 is missing in the information model repository. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/DI/ is required by http://bos.org/ with a minimal publication date from 03.11.2022 but the device has only a model from 09.03.2021 installed. Probably the information model from 09.03.2021 is missing in the information model repository. Build complete -- 2 errors, 1 warnings : No download possible I think the problem is that the UA Core nodeset is implemented in the PLC firmware (at least that in Siemens S7), and that only includes the "old" nodeset from 2021-09-21 etc. So the question is, how (or if?) can I transfer the new nodeset to the PLS? I have created separate Information models under Communication manager with the newer code nodesets (UA and DI). But it seems that the compiler does not recognize them being excising, neither in the Codesys IDE or on the PLC. Would have guessed that this is a common issue, sine many manufacturers use the latest versions of the OPC UA standard, and that it would be a solution to the problem.

My PLC is Wago 750-862. The detailed error is - " connect: Connection refused Write attempt from invalid socket. " Any help would be appreciated.

Post by transmin01 on PCAN serial "No CAN driver found" ^{CODESYS Forge talk (Post)}
Hi, I am using a PCAN mini CAN board which has the Windows drivers installed on the target PLC. PCAN board can be seen in device manager. However, I am getting "No CAN driver found" error. I have read the post https://forge.codesys.com/forge/talk/CODESYS-V2/thread/44aae19318/ and have uncommented the CmpPCANBasicDrv driver in the CodesysControl.cfg file in development PC and have copied it to the target PC. Current CodesysControl.cfg file attached. Is there anything else I am missing? Regards

Post by manuknecht on Detect "Cancel" Press in FileOpenSave Dialog ^{CODESYS Forge talk (Post)}
When using the FileOpenSave dialog and using the Visu_FbFileListProvider FB as an In/Output I could not manage to detect the difference of pressing the "Load" button on the dialog vs. pressing the "Cancel" button. In both cases, the selected file is updated if the dialog is closed when checking using the Visu_FbFileListProvider.GetSelectedFileName() command. How can I prevent reading or writing of a file when the "Cancel" button was pressed?
