Post by vformanek on No source code available for profinet library ^{CODESYS Forge talk (Post)}
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.

Hello @eschwellinger, Why not using one of those 2 folders: C:\ProgramData\CODESYS C:\Users\Public\Documents\CODESYS The main reason is depending on the company and the user right, the end user may not have the access to use those folders. Also having a non version dependent folder may help if the end user uninstall a previous version and forgot all its sample project where in this previous version installation. Thanks.

Post by rafael on Access to user group IDs ^{CODESYS Forge talk (Post)}
Hello, I'm trying to access the group IDs of the connected user. "CurrentUserGroupId" var shows only the first group ID that the user is assigned, I need the other group IDs that the user is in. I find some structs but I can't find where they are used, like "VUM_User" scruct from visuusermgmt, where can I find this vars? https://content.helpme-codesys.com/en/libs/VisuUserMgmt2%20Interfaces/Current/VUM_User.html abyUserGroupIDs seens perfect but I can't find a GVL where it is used.

Post by aliazzz on Unable to deploy Virtual Control SL on ARM64 (Raspberry Pi5) ^{CODESYS Forge talk (Post)}
An interesting remark for CODESYS Support. I found this after looking through the Runtime Deploy Tool messages when I connect to an AMD64 architecture Successfully Connected to Target ( {MyIP} - AMD64 ) when I connect to an ARM64 architecture (Raspberry Pi5) Successfully Connected to Target ( {MyIP} - ) As clearly seen in the attached .png, the AMD64 target is detected, while the ARM64 target architecture is not detected (displayed). I assume that this is the reason why the pulldown menu isn't populated correctly.

Post by schweizer on Position und Größe optimal anpassen (Container.Height - Visu.Height) funktioniert nicht. ^{CODESYS Forge talk (Post)}
Hello forum Does anyone have experience with optimally adjusting the position and size of the visualization elements? For us, the adjustment on the x-axis works in Codesys 3.5 SP20 with (Container.Width - Visu.Width). However, the y-axis is not affected with (Container.Height - Visu.Height). We implemented this according to the example from Codesys "Optimally adjust position and size" and had no success. Thank you very much for your help.

Post by kleeswi on Visualization scaling problem with B&R T30 panel ^{CODESYS Forge talk (Post)}
I have found a work around. I have written a python scripts that runs on user login (entry in .bashrc) which overwrites the webvisu.htm and webvisu.cfg.json file with the configuration for the B&R T30 panel (resolution and disable scaling). First I tried to add this setting to the the CODESYSControl.cfg, but that does not work following the big CODESYS Control V3 Manual. [CmpTargetVisu] Application.WindowPositionX=0 Application.WindowPositionY=0 Application.WindowSizeWidth=800 Application.WindowSizeHeight=480

Post by jinlee on Camera RTSP Feed ^{CODESYS Forge talk (Post)}
Hi, I followed your guidance and used go2rtc. There is a link generated from go2rtc I can copy into the web browser element in the visualisation. It somehow only appear within the software when it is running, but not on the webvisu. I want to display the camera feed onto the webvisu. My camera is reolink 810a which supports IP protocol. My project is pretty simple, just a web browser element with assigned URL.

Post by garmusd on Raspberry Pi 5 GPIO not working. ^{CODESYS Forge talk (Post)}
I paid money for the RPi runtime because the Product Description says that GPIO is supported. It is also written in the Versions that since 4.11 RPi5 is supported. And I use 4.13. Nowhere is it mentioned that GPIO is still not supported... It's a pity that the Codesys developers still can't find a way to fix it. Are there plans for when it will be fixed or are the developers too weak? Just wondering, is there anyone with a working GPIO? Can you share the details of your system?

Post by dogulas on Removing a symbol from the IEC Symbols Editor grid ^{CODESYS Forge talk (Post)}
Right now when I make a change to one of the tags in my code, I have to completely remove the IEC Symbol Publishing object from the tree view and re-add it. Then I have to completely re-add every symbol to the grid view by dragging them over. This can be a lot. Surely, this is not the intended behavior. Can anyone tell me how this is supposed to work?

Post by janp on IFM Controller Connection Issue ^{CODESYS Forge talk (Post)}
Hi everyone, I’m using an IFM ecomatBasic CR413S controller and having trouble connecting it to CODESYS 3.5. I have CODESYS SP18 installed, as recommended in the manual, and I’ve tried different patches. I’ve also installed all the packages provided on the IFM website for this controller. I can successfully connect to the ecomatBasic template, but I’m unable to connect when using the CR413S-specific template that includes all the inputs and outputs. Has anyone encountered this issue or knows a solution? Best regards, Jan

Post by mputaggio on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

Post by wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

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 culius on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
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?

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Didn't help. I'm just trying to understand why the errors occur. Are they from the poor driver or from the Linux network stack. That's why I wanted to know how the rxerros and lostframes are counted. Because in other places (like ethtool info) there are no any issues. And the Ethercat device works fine. And it also strange that on the second ethernet port with a different HW and driver Ethercat works better, but still time to time gets such errors.

Post by timvh on Codesys virtual control redundancy ^{CODESYS Forge talk (Post)}
I think it depends on what you consider as redundant. Is it allowed to plug the network cable in another device (server), move the USB key with license to the other device (server) and then start it up? Or should it automatically switch over within msec and take over the communication with the I/O flawlessly without noticing the switchover? We helped several customers setting up the CODESYS Redundancy functionality and the nice thing is that when you have it up and running, you can easily switchover from active to passive and when you download a new applicaiton, CODESYS handles the update of boot project on the passive controller automatically. Sure this will require an additional license and the license for redundancy, but if your installation is that critical it should be worth it. Please contact us (Extend Smart Coding) if you need any further information. We could help you setup the configuration and possibly provide the licenses for it (I noticed you are situated in the Netherlands).

Post by rabaggett on Reading Named Pipes in Linux Is there a better way? ^{CODESYS Forge talk (Post)}
I have a Python program that will handle things in my application such as VISA over IP and Telnet control of instruments. I want the main control and HMI in Codesys. My problem is communication between the two. I have looked at several ways to accomplish this, and settled on having the Python program create two named pipes, one to send information to Codesys, and one for Codesys to send information to Python. The information would be packetized with \n for end of packet.. Seems simple. I think the named pipes method should work, but file reading in Codesys using the CAA file library starts to get difficult when the file is never ending, as in this case. Before I spend too much time making something that may be fundamentally flawed I want to ask. Is there a better way? Is there a way to read the file 'one line at a time' which might solve my never ending file problem? Thanks!

Post by manuknecht on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
I managed to find a solution that seems to work reliably. As the VU.Globals.CurrentClient-filter accesses the CURRENTCLIENTID or at least a similar, internal variable it can only be used if called from a certain client (e.g. from a button in a visualization). My solution works by implementing a new client filter that compares the client ID of all clients to the ID of the last client that was used. The variable containing the data of the last client is defined as: G_LastClient : VU.IVisualizationClient; // Copy of last client that detected click This last client is then updated every time a button is pressed using the Execute ST-Code input configuration of the button: G_LastClient := VU.PublicVariables.Clients.Current; Next, I created a function block that implements the client filter interface as so: FUNCTION_BLOCK FB_LastClientFilter IMPLEMENTS VU.IVisualizationClientFilter VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR END_VAR Then i added a method to the FB called IsAccepted which is used to filter out the client. When creating the method, it should automatically be filled with the according variable declaration, as it is defined in the interface: (* For every client can be desided, if it is accepted. ``TRUE``: Client is accepted*) METHOD IsAccepted : BOOL VAR_INPUT (* The client, to check*) itfClient : VU.IVisualizationClient; END_VAR Now the client can be compared to the last used client as such: // check if clientID corresponds to clientID of last recorderd client IF itfCLient.ClientId = G_LastClient.ClientId THEN IsAccepted := TRUE; ELSE IsAccepted := FALSE; END_IF To make use of this custom client filter, initialize a variable with the client filter: LastClient : FB_LastClientFilter; // Client filter to find last used client Then use this client filter when opening or closing a dialog from ST: fbOpenMyDialog(itfClientFilter:=LastClient,xExecute:=TRUE,sDialogName:='VIS_MyDialog_DLG');
