Hi, How can you access the <root> of the Linux system? I'm struggling with this as the code above results in an invalid handle, as it cannot access '/'.</root> I am using Control for Raspberry Pi for context. Thanks.

After carefully studying the documentation, I have a question: is a second hardware-independent time source required for the correct operation of the VirtualSafety system?

Hello, I can use {attribute 'reflection'} FUNCTION_BLOCK POU VAR {attribute 'instance-path'} {attribute 'noinit'} str: STRING; END_VAR to get name of FB. How I can get the comment of FB, in the same way in the FB? Thank you for your time!

For sure you must use LEN(). SIZEOF() means you write a number of bytes based on the size of the variable type. For your STRING this will be 80 characters, but this will write unexpected characters in your file.

Thank you for your answer. I did install certificates, especially for OPC UA Client/Server tests. This OPC UA PubSub test uses pre-shared keys, not certificates. By the way, I do you 3.5.22 patch 2.

For the DynamicText error i have finally found a solution. You have to delete some libraries from your project. For me it was the WagoSysIcon library which wanted to reference dynamictexts even though i didn't have any in my project.

I guess you could archive the project, open the archive and go online. Is that suffiecient for your use case?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
