You could try using the VUM_UserGroup struct from the VisuUserManagement library. I haven't tried this, but there is a variable for tAutoLogout to set the logout time.

Post by mainak on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
Hello all, I am using the OPC UA server with my custom information model. I have used the communication manager to add my information model under my application and created instances from OPC UA types. I see that the created instances in the OPC UA server has some opaque nodeid (attached screenshot) and I want to change that. Therefore I have the following questions: 1. Is there a way to configure the NodeIds of instances in the OPC UA server? I tried to edit it using the UaExpert client but got error "BadNotWriteable". is it possible to configure it somewhere so that the nodeids can be changed using an external client? 2. Is there a way to define the rule for creating instance nodeids within the codesys IDE? 3. Is it possible to create the instances before e.g. using a modelling tool like UaModeler and import them as part of the information model and use them later? Using the communication manager, I can only create instances from types. I couldn't find a way to map my existing instances to plc tags from my application. It would be nice if someone could help me with these issues. Thanks in advance. :)

Post by nikgind on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi I am trying to import a custom information model that I created using UA Modeler. I have only added two new methods and two new object types. It is possible to add the information model to the Communication Manager and the two new object types are shown in the Information Model tab. After compiling i get the following error: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://yourorganisation.org/Bsp_3.1/ 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. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway I have installed the information model from 15/12/2023 but not from 15/09/2021. Which makes the error message even stranger.

If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Post by bjarne-pagaard on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
I just had the same problem in 3.5 SP19 Patch 6. Trying to use a textlist for Combobox Integer element. The textlist cannot be selected in the IDE, and is not found when manually entering the name. The textlist is copied to the device, but is not used. Can confirm, that copying an existing textlist and renaming it does work.

Post by timvh on Library ENUM text representation in visualization ^{CODESYS Forge talk (Post)}
Probably the enum from the library doesn't have text support. In that case you need to add your own TextList to the application. In the rectangle you should use the property "dynamic text" to link this object to the textlist which you have created yourself and then link the text index to your enum variable.

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hello guys, I have the following problem with the Codesys visualization (4.6.0) and Codesys V3.5.20.20. I would like to use my own HTML5 elements for my visualization. To do this, I have to select the option “Support client animations and overlay of native elements” in the visualization manager. But with the selection of this option, the visu has a massive loading delay when changing frame content. This happens even if I have not even added HTML5 elements. However, if this option is deactivated, then changing the content of the frames works without any problems, it loads instantly. I have already tried to change various refresh rates but without success. Have any of you experienced this and been able to fix it?

Post by rer-code on Codesys 3.5.18.60 – Application Loss and Persistent Data Corruption ^{CODESYS Forge talk (Post)}
Hi, I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where: All persistent variables are lost. Attempting to log in results in the message: “The application does not exist on device. Do you want to create it and proceed with download?” The log shows: “Loading retain-data/bootproject failed.” From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm or resolve this issue. If anyone has encountered something similar or has suggestions for troubleshooting or preventing this, I would greatly appreciate your input. Best regards

Post by mondinmr on Something of strange in the trace ^{CODESYS Forge talk (Post)}
I noticed something strange in the trace: one of the variables (specifically parts.servoFeeder.m_pathGen.m_acPos) is showing an absurd or unrealistic value—something around 4E+18. However, when I check the same variable in the watch window, it shows a normal and expected value (around 506). Do you know why there is this discrepancy between the trace and the watch? Could it be a bug in the trace tool? Thanks in advance!

Post by timvh on Licensing info not available. ^{CODESYS Forge talk (Post)}
In the VPLC configuration settings there is an entry for the IP address of the license server. In this setting fill in the IP address of your device (host IP address). Then when the virtual PLC starts up, it will get the license from the license container on the host. You can do this for all VPLC's running on your device. The VPLC will always take the smallest license which fits the required license. So if you have 2 licenses for VPLC's with small and large applications, then this will work fine if you start up one VPLC which requires the small license and the other which requires the large license. PS, personally I find it much easier, especially for testing and experimenting, to activate the licenses on a CODESYS (USB) key. This is easy to activate (on your development PC) and easier to move to another device. Addtionally you don't loose the license when you need to install a completely new image on the device.

Post by fabiodasilveira on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Hello Everybody, I have created a project for an Eaton XC303 that sends lots of data to a router via UDP. It works fine. However, when there is more than one product connected to the router, then it is necessary to change the IP address of the Ethernet port 0, from e.g. 192.168.2.11 to 192.168.2.12 (second product). It is easily done via PLC Shell (setipaddr 0 192.168.2.12), but the people in production is struggling with the PLC Shell commands and I would like to create a Visualization page that will hide that. I used the instruction: eChangeIPResult:= SysSockSetIPAddress(strEthernetPort, strIPAddress); and it works, until the PLC resets. I already read some posts and it appears that I need to stop the Ethernet 0 port and Reconfigure it, but I am really struggling to find the right way to do it. Any help will be much appreciated.
