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 dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Hello, I'm using CR711S from IFM and I would like to use the CAA Can Low Level in de Safety part. I already use it on the Standard part and it works properly. I would like to know if there is some restriction on using it on the safepart of the PLC (I tried but my PCL put himself in Stop...) ? And if you have some example or even a forum with some types on IFM and CoDeSys, I would Take It. Have a nice Day.

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 tk096 on Fieldbus has lost synchronicity ^{CODESYS Forge talk (Post)}
Hi, a few suggestions on how to tackle the problem: - it might help to increase the cycle time of the ethercat task - increase the value of the ethercat parameter DCInSyncWindow (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/DCInSyncWindow.html) (see attached image) - enable FrameAtTaskStart (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/FrameAtTaskStart.html) in the ethercat master (see attached image) - if the drives can handle the synchronization problems, checking of the synchronization can be deactivated using SMC_Set_ETC_DCSyncSupervision (https://content.helpme-codesys.com/en/libs/SM3_Drive_ETC/Current/SMC_Set_ETC_DCSyncSupervision.html).

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.

I bought and installed SoftMotion Light now. When I try to add a SoftMotion Light Axis to my stepper drive and I go online it shows: "The license is missing or invalid". See picture What am I doing wrong? This is the right way right? First add your EtherCat XML-File from your stepper driver and then add the SoftMotion Light axis right? Thanks for your help esave

there is a new problem with latest bootloader version. The problem seems to be: Version from2024-04-20 does not work-> 2024-01-15 version works the workaround is a rollback to January version: cp /lib/firmware/raspberrypi/bootloader-2712/stable/pieeprom-2024-01-15.bin ./pieeprom.bin rpi-eeprom-config pieeprom.bin > bootconf.txt rpi-eeprom-config --out pieeprom-new.bin --config bootconf.txt pieeprom.bin sudo rpi-eeprom-update -d -f ./pieeprom-new.bin sudo reboot

Post by herbasso88 on WebVisu flickering ^{CODESYS Forge talk (Post)}
Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking problem happens. Also, the problem is only at the WebVisu page, the "normal" VISU pages (the ones opened when Codesys HMI start) work always perfectly. Another strange thing is that the problem happens only if on the same page, where there is the meter object, there is also a trend object!?!? Codesys HMI is running on a Virtual Machine (VMware Workstation 15 player, v.15.5.6) running Windows 10 Pro N 64-bit. The blinking problem happen also if I convert the project to Codesys 3.5.20.0. This version of Codesys and Codesys HMI are installed on a Virtual Machine running Windows Server 2019 Standard 64-bit. In attachment the archive of my project. The attached project has only one page, if "Enable Counter" is not pressed the "End of area" variable of the meter is not updated in the software, and everything work well, normal VISU and WebVisu; if "Enable Counter" is pressed, the "End of area" variable of the meter is updated in the software, and the WebVisu page start blinking. I tried also to enable the "Support client animations and overlay..." property at VisualizationManager, this seems stop the blinking problem, but that property also destroy my WebPage, moving almost all the graphical object, that also seem not working anymore. I really need help to understand what I'm doing wrong, I have to develop a bigger project and I have to understand if trend objects and animated meters cannot stay in the same page. In the final project the WebVisu will be very important because the customer will use this way to access the application to monitor the process. Regards

Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

I'm looking to automatically select a text field element in my visualization. I'm not sure if this is possible, as I don't know how to get the data on specific elements. I am wanting automatic selection of the text field, as I am using a keyboard-input barcode scanner, which should always input the barcode into the text field whenever a barcode is scanned. Does anyone know if this can be done?

A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

Does anyone know how I can select a specific POU in the navigator? Or how I can open a specific POU? I can retreive the guid of the POU. Thx

Thank you very much for your reply. That helped, it is editable if the library is at root level. Unfortunately, I noticed that I am not using the MQTT client SL, but the AzureMQTTClient from the Azure IoT Hub Client SL library. At first glance, there is no parameter to increase the message size. Does anyone know how to increase this in the library or is it simply not possible here?

Hello New W11 machine. I've tried installing and the 'Codesys installer' appeared, which basically failed. This was the exe from the Store. I've now tried installing with an old copy of SP17, which didn't try and use the Codesys installer, but has hung at the 'Install all packages added to the setup' stage. Has the exe been updated to use the Codesys installer? What is the installer? Do we think it'll work on w11? thanks, Paul

Hello, i am trying to find a way how to open Dialogs on a Single Visu. The options from VU.Globals are Target and WebVisu, but Webvisu opens the Dialog on both WebVisus and it should be separated. CurrentVisu can only be used when the Dialog is called from the Visu, but its all done in the Code. One Webvisu is for the User and one is for diagnostic reasons, and they should not be interfered from each other. Maybe someone can help me with this. Thanks

Post by wollvieh on License Activation Problems ^{CODESYS Forge talk (Post)}
on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.

I can log in to the controller and I can see and control all of the fieldbus couplers that I have. I am unable to get the internal bus working.

Post by mikek10 on Error IoDrvEthernetIP: Connection Failure. (16#1) How to solve ^{CODESYS Forge talk (Post)}
Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)
