Post by miltos on licensing question ^{CODESYS Forge talk (Post)}
Greetings to all, I'm working on a webvisu project on control win V3 x64 runtime, and have purchased 3 licenses for my application. -Codesys Control Standard M -Codesys Visualization L -Codesys Communication M I have them installed on a Codesys usb dongle When I try to download the program, a login error window appears with the message "No valid license found for the webvisualization". The control win v3 communicates with 3 plc, and have enabled communication over codesys V3 communication by adding one datasource for every plc in the datamanager. If I remove the data manager from the project, the rest of the visualisation can be downloaded normally. Do I need to purchase another License and which one? Please find attached the software metrics and the error screen.

Post by arjunk on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
I’m trying to integrate a custom PLC into CODESYS so that it appears under the Device section. From what I understand, this requires a .devdesc.xml device descriptor file. I attempted to create the XML manually, but whenever I try to install it in order to generate a .package file, CODESYS crashes. CODESYS version: 3.5.21.20 Target PLC: Linux ARM64–based My questions are: Is there an official or easier way to generate a valid .devdesc.xml file for a custom PLC? Are there tools, templates, or examples that can help ensure the XML is structured correctly and won’t cause crashes? For Linux ARM64 targets specifically, is there a recommended starting point (e.g., modifying an existing device descriptor)? Any guidance or best practices for creating and packaging custom device descriptors would be greatly appreciated.

How is that possible to put a Function Block Method in the Task Configurator, as they did in the CNC3DEditor.project example? In that exmaple, I removed the gCNCMachine.SlowTaskCall method from the Task Configuration and I can't put it back. https://us.store.codesys.com/cnc-3d-editor.html Thanks!

Post by timvh on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
I'm not sure what you are trying to do, but getting the CurrentUserGroupID like this will not work, because there could be multiple Visualization Clients and each can have a different user that is logged in. Also when you go online with CODESYS and open an Visualization, this is counted as a client. Probably this is the reason you see it changing. What you can to is "iterate" over all clients and then see which user is logged in on which visualization Client. For this you need to add the Visu Utils library to the project and call the FbIterateClients. See https://content.helpme-codesys.com/en/libs/Visu%20Utils/4.4.0.0/VisuUtils/VisuActionUtilities/Function-Blocks/FbIterateClients.html fbClientIteration( xExecute := x_Execute, itfClientFilter := VU.Globals.AllClients, itfIterationCallback := fbIterator, xDone => x_Done, xBusy => x_Busy, xError => x_Error, eError => e_Error); The fbIterator, in the example above, should be an instance of an FB which you have created yourself and this must implement VU.IVisualizationClientIteration. For example: FUNCTION_BLOCK FB_ITERATOR IMPLEMENTS VU.IVisualizationClientIteration Then automatically the corresponding methods will be called. In the HandleClient Method, you will get an interface to the client(s) and then you can get the current user through this interface: itfClient.UserGroupId You can also get the UserName: itfClient.UserName

Post by wiresplus on How to Connect / Go Online without re-downloading the project ^{CODESYS Forge talk (Post)}
Hello, I have a PLC in a remote location. I can connect to it, but when I use a different PC, it asks me to re-download to the PLC - which will a) interrupt production and b) cause version issues. Codesys being open-source, if someone else has made changes, I need to be able to connect, upload the current project, compare it with mine and then decide what next. Every time I connect, it says Warning: An application 'Application' is currently in RUN mode on the PLC. As there is no matching compile information, this existing application needs to be replaced. Click 'Yes' to download the latest code or 'No' to abort. What am I doing wrong?

I also would like to now how to clear the PLC Device Log. @eschwellinger are you saying there is no way to clear the log? When I am debugging I want to clear the log, it would make things some much easier to find.

Post by fabiodasilveira on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Thank you, Bingo. Your idea of adding the change to the start up process works. However, I am still intrigued with the fact that SysSockSetIPAddress(strEthernetPort:= '0', strIPAddress:= '192.168.2.12') is different from PLC Shell (setipaddr 0 192.168.2.12).:-(

Thank you very much Florian The SoftMotionLight package is actually more expencive than the normal SoftMotion. What is exactly the difference? Does my PLC need to be compatible with SoftMotion or does this work with any PLC?

Most likely related to the Device Diagnostics functionality. Double click on your device (PLC), go to the tab "PLC settings". Enable the advanced option "Enable diagnosis for devices". Build your application again.

Post by tokamk on Dynamic setting of the modbus tcp/ip slave ip address ^{CODESYS Forge talk (Post)}
Hello, I'm working on a project which includes Panel-PC which communicates with a PLC through Modbus TCP/IP. On the PLC I have a CODESYS code which has Modbus slave objects. The Modbus slave objects have to have manually set IP address in order for them to work properly and the Ip address has to be the PC-Panels's IP. This project is going to a customer and they're using their own IP address realm. So, my question is that is it possible to configure these slaves in some other way, so that the customer doesn't need to modify the CODESYS project? I was thinking that would it be possible to set the IP address of these slaves from external source?

Hello, I am struggling with Edge gateway to the automation server. It is not possible to establish the link. When I create the Edge in codesys and get it to Automation server, it is red, unable to connect. Scan fails. RPi 4B Runtime 4.13.0.0 Edge gateway 4.13.0.0 Codesys 3.5.2.40 Any idea what to chase? I have been using previous versions of edge gateway. Now I updated all to latest versions, failed. Frustrating.
