Hi, I was faced with the same problem. But I could fix it for me.

It noticed that fault message on some windows systems, while other ones were working fine.

A had a problem with my python script on that systems. So I went to python consol and executed the commands step by step. This is, where I got this fault message. However I don't get that fault, when I run the script normal like "py script.py". In this case the following command (after import...) was failing, that was supposed to start a TIA session. What I found out was, that it didn't work with default () parameter, but I had to give the parameter explicit.

Discord? What do you mean?

😀 sounds like a lot of work. I prefer staying in public. I might not be the best one to support you.

Hey Georg,

I fixed the previous problem. It wasn't working in Jupyter Notebook, but it worked in a .py script. I'm not sure why.

However, I'm now facing a new problem. I'm trying to export HMI tags, but I'm getting an error. Here's my code:

processes = tia.TiaPortal.GetProcesses()
process = processes[0]  
mytia = process.Attach()
myproject = mytia.Projects[0]

software_container = tia.IEngineeringServiceProvider(myproject.Devices[1]).GetService[hwf.SoftwareContainer]()
software = software_container.Software   ## error here  

tags_hmi = software.TagFolder.TagTables.Find("test")

The error message says: 'NoneType' object has no attribute 'Software'. However, when I check in the Siemens Openness Explorer, I got a code snippet that looks like this: (TiaPortal.Projects[0].Devices[1].GetService().Software as HmiTarget).TagFolder.TagTables.

Do you have any tips on what might be causing the error?

Also, do you happen to know if there is an HMI discrete alarms function in the V16 .dll? I checked the 2021 manual, and it seems like there is a function for it, but my .dll doesn't seem to have it."

Hi, ok, so for your previous problem the same solution helped for you that also worked for me...

For the other problem I have no idea.
