6.3.2 Add safe AS-i slaves to the project
43315
Safe AS-i slaves are added to a CODESYS project in 2 steps:
1. Add logical device of the safe AS-i slave to the project tree:
→Add logical device to the project tree (→ S. 26)
2. Configure logical device:
→Configure logical device (→ S. 29)
The user is responsible for the selection of the suitable logical devices. The user must ensure
that the selected logical devices provide the functionality required for the safety application to
be implemented.
► Observe the documentation of the logical devices (→Logical devices for safe AS-i
slaves (→ S. 205))!
A logical device with a defined AS-i address must only be added to a safety project once.

Safe AS-i slaves are added to a standard area of device tree into the CODESYS project via the nodes
[SF_ASi_Master_1] and [SF_ASi_Master_2]:
Safe AS-i slaves connected to AS-i Master 1:
Safe AS-i slaves connected to AS-i Master 2:
To add a safe AS-i input or output slave to the project:
Requirements:
> Safe AS-i slave is correctly installed and addressed.
> AS-i network is projected.
1 Select AS-i network
► In standard area of device tree: Mark safety nodes of the AS-i network in which the safe AS-i slave is installed:
– for AS-i 1: [ASi_Master_1] > [SF_ASi_Master_1]
– for AS-i 2: [ASi_Master_2] > [SF_ASi_Master_2]
