4.3.3.4 Alias devices
The communication between the safety logic and the I/O level is realized via an alias level. At this alias level
(subnode
Alias Devices ) corresponding alias devices are created for all safe inputs and outputs, and also for
standard signal types. For the safe inputs and outputs, this can be done automatically via the I/O
configuration.
The connection- and device-specific parameters are set via the alias devices.
Fig. 29: Starting the automatic import from the I/O configuration
If the automatic import is started from the I/O configuration, a selection dialog opens, in which the individual
terminals to be imported can be selected.
