Post by martincapd on EWON ^{CODESYS Forge talk (Post)}
I have the same problem in that I can connect to the eWon and ping the controller IP Address, however I cant connect through CodeSys. I'm using Gateway-1 which is configured to use "IP-Address: localhost" and "Port: 1217". Rather than scanning the network for devices, I enter the IP Address of the device, codesys returns a "No Device is repsonding..." message. See attached. I'm wondering if the IP-Address used Gateway-1 should be "localhost" or the WAN/LAN IP of the eWon? Thanks for the help MC

Post by dominggus on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I still have the same problem even when updating to CODESYS Recipes 4.3.0.0. My scenario: I'm trying to save/load an array of structs using the Visu: - Execute Command > "SaveRecipeAs" works properly - Execute Command > "LoadWriteRecipe" works not entirely: the structs of array[6] and array[7] should have been empty but were duplicates of array[4] and array[5]... the struct contains 26 variables and the array's length is 30.. Maybe there is a upper limit on recipe variable count?

Post by andrej on POU - Access to runtime ^{CODESYS Forge talk (Post)}
Hello all, when creating a POU, the Codesys IDE allows the setting "Enable System Call" (in the Settings, Property -> Build), see picture. The name suggest, that runtime functionalities i.e. functions of codesyscontrol such as "stop plc" etc. can be directly called. I tried various approches without success, the following does, unsurprisingly not work. FUNCTION accessRTE: BOOL; ****************************** codesyscontrol.stop(); Can you please tell me how I can make a system call to codesyscontrol from a POU. Or could you provide me with a use case for this setting. Many thanks for your feedback and kind regards Andrej

Nano goodmorning and thanks for the reaply, the links I have to manage are links as the following: https://192.168.1.101/u-os-app-codesys/application/visualization/webvisu.htm I saw that with Wikipedia or other web sites the tool works but not the link above. "google and some other providers, prevent from using as iframe and similar injections." The goal I'm pursuing is to display remote graphical user interfaces from a local graphical user interface over a local network. thanks in advance, Riccardo

Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

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

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.

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

Post by yannickasselin on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

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...

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...

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?

Hi, I clone a git repository with VersionUpdateFlags.SilentMode, works fine But now I want to checkout a specific commit (with branch_copy command). When using the branch_copy command there is no VersionUpdateFlags and I get this annoying "Project Environment" prompt, blocking further execution of my script without user input. I already tried something like system.prompt_answers[???] = PromptResult.Cancel but I don´t know the string I need here.. The goal is to have a script that clones a repository and compiles every tag + create compiled libraries.

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
