Controlling real applications with TwinCAT Ethernet Protocol
Attention
For controlling real applications choose necessarily the TwinCAT Ethernet Protocol,
not the TwinCAT Ethernet Protocol for all Network Adapters!
The TwinCAT Ethernet Protocol for all Network Adapters just an evaluation protocol to
test TwinCAT also with other network adapters that have no Intel chip set. It supports
no hard real time and may cause jitter!
The TwinCAT Ethernet protocol should now be displayed in the list of components.
