Configuration via TwinCAT System Manager
Disable Automatic Windows Updates
Attention
The advantage that TwinCAT real-time Ethernet uses standard hardware comes with a
small disadvantage: Windows knows this standard hardware, but during a Windows
Update or during installation of a Service Packs it will try and install the latest drivers
that it considers to be the "best" drivers for this hardware, which means that it may
overwrite the TwinCAT driver for real-time Ethernet.
Remedy:
Automatic Windows Updates can be disabled. For manual updates, the suggestion to
replace the Intel Networking Driver should not be accepted.
After the installation of a Service Pack, the TwinCAT driver for real-time Ethernet
should be re-installed and the TwinCAT Ethernet protocol should be reactivated.
Readiness for operation of TwinCAT real-time Ethernet can be checked via the
TwinCAT Ethernet compatible devices screen.
