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.

We are working on a project and the customer required 3.5.16 BF4. After working on the project for a few weeks I opened it the next morning and it could not access libraries. IecVarAccess could not be accessed. I checked if windows updated - it did not. So no explanation for why it lost access other than that I shut down the computer for the night. Note that I am using a demo license. I still haven't figured out any reason to purchase a license. So I spent the next hour reinstalling CodeSys. Note that I did NOT uninstall first. After install I waited another 5 minutes for it to open the first time. I clicked File->Open to open the project. Previously I had selected File->Recent Projects - not sure if that makes and difference. But after this process it did open the project and compile it just fine. This is miserable. If this had happened when I went on site to a customer I would have lost hours of work doing the reinstall. Is there a different and quicker fix?

Post by rmaas on Strange Behavior on Raspberry Pi
CODESYS Forge
talk
(Post)
Hello, what you are seeing is not strange behavior. The problem is that everyting is happening in the same program cycle. After the variable Stepnumber is changed from 10 to 20 for example then you want the program to wait with the next EQ until the next program cycle. Else every EQ will be be true because in every line the variable Stepnumber is increased. When the program arrives (still in the same cycle) at the line with the timer, the Stepnumber has been increased to 30 in the meantime and the timer will allway be ON because even though the variable is written to 10 in this line in the next cycle it starts with 10 and will be 30 again before reaching the timer in line 8. Not very good at explaining stuff but i hope you get the problem. See screenshot below for an example of one way you could solve this...

Post by wbj0t on What the right way to update TCP/COM slave device holding registers
CODESYS Forge
talk
(Post)
Hi all :) I have an plc. This plc has option to be as slave device. There are TCP -> Serial Slave Device and COM -> Serial Slave Device. There are 4096 ModBus holding registers with mark "internal modify" for the both devices above. So, COM Slave has 4096 registers and TCP Slave has 4096 registers. And, finally, I have an ARRAY[0..4095] OF WORD. This array glued with COM Slave and TCP slave. Yes, I need plc's opportunity to be communication both TCP and COM ways for the same registers. For example, the next task structure: * TASK_0: 1. pou_READ_Registers 2. pou_0 3. pou_1 4. ... 5. pou_N 6. pou_WRITE_Registers At the first pou I read registers for the other pous, after job we have sort of state of the plc. At the last pou (6) we write modified registers. It is a good scenario: some one wrote registers for the job, after job we save these (modified) registers. But, what if registers wrote between 1 and 6 pou by operator, for example, at the 3 pou -> the last pou 'pou_WRITE' will rewrite this request from operator. What the right way to work with this logic? Thanks you.

I'm now circumventing the problem by creating a separate TCP client for all Write actions. Upon registering a changed variable, I enable this client, until the change is processed.

Post by tariq on Using Hilscher CIFX Cards as EtherCAT Masters in CODESYS
CODESYS Forge
talk
(Post)
Dear Codesys Support Team, I hope this message finds you well. I am currently working on a project that involves using a Hilscher CIFX card to act as an EtherCAT master within the CODESYS environment. Despite following the available documentation and setup guides, I have encountered some challenges and require assistance to ensure proper configuration and operation. Questions: 1- Could you please confirm if the Hilscher CIFX card is supported as an EtherCAT master in CODESYS? If so, are there specific drivers or configuration files that need to be installed? 2- Are there detailed setup guides or example projects available that demonstrate the integration of Hilscher CIFX cards with CODESYS for EtherCAT communication? 3- Is there any additional software or plugins required for ensuring seamless communication between the CIFX card and the EtherCAT slaves within CODESYS? Your support and guidance on these matters would be greatly appreciated, as it is crucial for the success of our project. Thank you for your time and assistance. I look forward to your prompt response. Best regards, TB

I've noticed that exceptions in system event handlers don't stop the runtime or call the exception handler. I've included a very basic example to demonstrate. It seems likely this is undesired but unavoidable. Is that the case? Is there any advice on the matter? Thanks

I would ask the Wago Support - they have a CODESYS V3 runtime (not eCOCKPIT) which probably support this? At least worth to ask them.
