Twincat2 - Windows11 - Timeout problem
Hi!
I just updated from Windows10 to Windows11 with twincat Engineering x64 2.11.2314.
I have the following problem:
I open Twincat System Manager. There I can make an broadcast search to find my CX9001 CPU. I connect and add it to route. The user and password is checked correctly. After that step, I click on the route and get a yellow TIMEOUT.
I think the connection to my CX9001 is working, but not the route back to my client.
I tried deleting all routes with cerhost in the registry from CX9001.
Tried another VMWARE with win10 works again!
Has anyone information about that problem in Windows11 ? Thinking of defender could be the problem.
Thanks,
Klaus
For Windows 11, the route to the client PC must be manually created on the CX9001, otherwise a RST (Reset) will occur, visible in Wireshark (the CX9001 blocks the connection).
Steps:
-
Assign a static IP to the local PC using MAC address binding in the router
(in my case:192.168.1.30) -
Connect to the CX9001 via
CERHOST.exe -
Open Start → Run → regedit
-
Navigate to:
HKEY_LOCAL_MACHINE\Software\Beckhoff\TwinCAT\Remote
Add the following entries:
-
New Key: use the PC name (in my case:
BUEROPC) -
Under that key, add the following New DWORD values:
-
Flags=0(Decimal) -
Timeout=0(Decimal) -
TransportType=1(Decimal)
-
-
Add the following New String values:
-
AmsNetId=192.168.1.30.1.1 -
Address=192.168.1.30
-
See screenshot (
regedit_win11) – note that the AmsNetId may appear differently than entered due to formatting.
Final Steps:
-
Perform a Start / Suspend on the CX9001 to restart the controller.
-
In TwinCAT (on the Engineering PC), run a Broadcast Search to find the CX9001
-
Important: when adding the route in TwinCAT, use the IP address (not the name)
