Is it really the same CODESYS version with the same add-ons? Maybe open the CODESYS installer on your home laptop, and export the configuration. On your work PC open the CODESYS installer and import the configuration.

Does the OPC UA server have a generic username and password? It doesn't seem to be the same as the device username and password.

@eschwellinger - We are experiencing the exact same issue. RunTime 3.5.19.70 and IDE V3.5 SP21. It's 100% reproducible. All you have to do is disconnect the network cable for about 10 minutes. OPC UA Crashes and requires a reboot to fix.

Arrays with variable lengths are a bad idea. This makes your system unstable and can lead to crashes. Declare your array large enough to reserve enough memory

Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

if this happens I go to --> Build --> Generate code then there exists a IDE Code and a PLC/API code and comparison before download is possible. Give it a try?

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.
