Issue timeout on first read

[patopat]

Hi, Please, I need your help because I have a lot of timeout on first connection and I don't know why ? I run the Example program from library. The log file is attached.

I set 30 seconds for timeout and I get this following error :

Hi again - can you clarify what you mean by:

a lot of timeout on first connection

i.e.

• Does it always work if you try it twice, three times, four times?
• Does it work against other PLCs and not this one?
• Does it work against other Tags and not this one?
• Does it sometimes work against this tag, but not always? How often does it work (e.g. 20 times out of 100 attempts)

In the future could you provide a full code listing for your minimal reproducible example, there could be other factors at play.

Thanks for the debug log.

@timyhac I wrote an application 2 months ago and everything worked very well. Now, I have a lot of difficulties to connect to the PLC. After one day of debugging I noticed that is coming from Windows 11 22H2. My colleague also has problem to Ping the PLC with Win11 22H2.

I will mount a VHDX with Win10 22H1 and will try.

It sounds like you've confirmed the issue is elsewhere in the system?

[patopat]

@timyhac Yes I confirm that the issue comes from Win11.
