EL2911 and EL2911-220042 Version: 2.0.0
5.3.6 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.22: 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.
Fig.23: Selection from the I/O tree
The alias devices are created in the safety project when the dialog is closed via OK.
Alternatively, the user can create the alias devices individually. To this end select Add and New item from
the context menu, followed by the required device.
