Thanks Edwin. I have reviewed the example and I'm doing basically the same when calling the methods. The recipe files are in the right directory. Everything looks okay but simply it doesn't work. May migrating to Codesys 3.5.20 will solve this?

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?

CODESYS Forge

(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...

Can you post the new code that you have by chance? Also, are you able to send the values of tags dynamically with the RTAC in this JSON format? I'm running into a lot of road blocks with it.

the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

Post by farren on How to stay in a method until something is finished.
CODESYS Forge

I know I'm thinking about this wrong -- too many decades of procedural and event-driven programming and only a few months of PLC ST programming...... I've created a visualization with a button that when pushed calls a method. I want the method to take a pressure reading, wait one minute and then take another pressure reading. I'm looking for leaks. I'm using TON for the delay. It seems like what is happening is that the method gets called once and it takes the first reading and starts the TON. But then execution continues, leaves that method call, and the second reading never happens. I can force the method to keep running until the whole thing is done with a While loop, but I understand that is considered BAD in PLC programming. If it push the button again to call the method again, it picks up where it left off and if the timer is complete then it runs the remaining code. How do I keep that method running until it is complete with just one call without using a while loop that ties up the PLC for a minute? Thanks! -Farren
