If necessary, please select the "Target System" and the "Programming Language". Confirm
your selection with "Ok".
Communication between the Safety Logic and the I/O level is implemented via an alias level.
In this alias level (sub-node \ alias devices), corresponding "Alias Devices" are created for all
safe inputs and outputs, but also for standard signals. This can also be done automatically
for the safe inputs and outputs using the
I/O configuration.
