Hello, I have a Exor HMI with 2 seperatred ETH interface's. It is Configured as PN Master on ETH interface 1 and the IO's are working, as long as the development PC is connected to the ETH 0 interface. When the PC is disconnected, the PN communication drops and a reconnection is started. I installed the newest device description for Codesys and Firmware for the Panel. The IO Gateway is from Weidmueller What could cause the Problem?

Post by vsgn on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
Hi, in my experience, the best options for such a case could be: 1. Pass a FunctionBlock via VAR_IN_OUT, containing all variables, mehods and properties needed for the logic of this graphic element (be aware of implementing correcly both get and set accessor for properties) 2. Pass an Interface via VAR_INPUT, of which you can use obviously only Properties and Methods. This is much more elegant for me. Here, you can just pass directly the instance of a FunctionBlock implementing such Interface as input. Hope you'll find this suggestions useful.

Post by ojz0r on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
One thing you could do is create an object with the variable as field with a function and procedure to get the variable (read) and set the variable (write). These are then called from your program and the vizualization.

Post by moksan on Unconnected_Send Explicit message with Route Path ^{CODESYS Forge talk (Post)}
I have been trying out Unconnected_Send Explicit Message with route path.(The Unconnected_Send service shall use the Connection Manager object in each router to forward the message and to remember the return path. Vol 1.3 / 3-5.6.7) However, I could not see the correct path on Wireshark. I want to see the Unconnected_Send Message Service Code as 0x52 and also the last of the message should have the route path. I want to ask some questions about this topic. The IIoDrvEIPAcylicServices Interface has the IoDrvSendUnconnectedMessage Method. And there is a struct (EIP_SendUnconnectedMessage) for this service. But there is no information about how to implement to project, and if it is successful, does it send a message with 0x52 Unconnected_Send Service Code or not? If that is not a solution, how can I set the Unconnected_Send Explicit Message struct on Codesys? Also how can I send explicit message with route path?

Post by pouyavakili on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
❓ Issue: TestManager Not Available in Python Script (AttributeError) 🙏 Question: Why does project.get_testmanager() not work in scripting, even though Test Manager is installed and licensed, and the script runs in GUI mode? Is there a way to ensure the Test Manager interface is loaded or accessible from the scripting environment? 🧠 Summary: I'm trying to automate test execution using the CODESYS scripting engine (Python) via a script that opens a project, builds the application, and runs tests from a TestRepository.xml. Although the Test Manager works manually in the IDE, it fails when accessed via script with the following error: AttributeError: 'ScriptObject' object has no attribute 'testmanager' 🧪 Test Setup: CODESYS version: 3.5.21.10 Test Manager: Installed and licensed (works in the IDE manually) Project: Contains a test repository, which can be executed via the GUI Script execution method: powershell Start-Process -FilePath "C:\Program Files\CODESYS 3.5.21.10\CODESYS\Common\CODESYS.exe" ` -ArgumentList @( '--profile="CODESYS V3.5 SP21 Patch 1"', '--runscript="C:\Scripts\run_tests.py"' ) -Wait 📜 Script Summary: python project = projects.open(project_path) application = project.active_application application.build() This fails: testmanager = project.get_testmanager() ❗ Problem: Calling project.get_testmanager() or application.testmanager throws an AttributeError, even though the same project and test repository work in the GUI.

Post by pernockham on Pointer/reference to Codesys trend recording object? ^{CODESYS Forge talk (Post)}
I have a Hmi that acts as an interface for many (mostly identical) units. This is managed by a sort of "mux" where you select which unit that should be presented on the HMI. Backbone is solved by a HMI-gvl defined as reference/pointer to "unit-data", which then can be set to the individual units. While this works for most data I still have not sorted how to solve this for the trend recordings. One solution would be to have already "mux:ed" data values as source for the/one trend. However then the trend would contain data from different units/sources which could/will cause confusion. If its possible to "clear" this can be mitigated. Possibly let the trend have its own "mux-selector" (ie, the hmi are focusing on unit#3 however trend data is locked on unit#5), that could also work.. Or, let each unit have its own trend recording, which is focused if the unit is "selected". Can I reach the trend recording objects programmatically (those defined in the device tree)? Ie, can I use a "reference/pointer to these trend recording objects"? There is a field "data source" in the trend properties dialog which seems to resemble what Im looking for? But Im not sure if I can use it in some way, I cannot change anything in this field it only says <local application="">. </local>

Hi, a few questions that you can check regarding your kinematics: * Does your kinematics FB implement the interface ISMKinematicWithInfo2? * Does AxesToCartesian(a, out f) -> CartesianToAxes(f, out aCompare) result in a=aCompare for random positions a? * Do you return a valid rotation matrix f.mR (SMC_Matrix3) in AxesToCartesian()?

Most likely your IP address is set to 172.... because you use a VPN connection to your device. Probably best to use the other Ethernet interface for your modbus communication.

Could you send a screenshot of the Ethernet "General" settings? In that screen you can also search for the Ethernet interface you would like to use for your communication. Did you do that? Did you change any settings manually in the CODESYSControl_user.cfg?
