Configure logical device
Configuration is made via the node [Logical I/Os] in the safety extension area of the device tree. All
safe AS-i slaves inserted in the project are listed there as sub-nodes.
To configure the logical device of a safe AS-i slave:
► In the safety extension area of the device tree:
Double click on the symbol of the logical device at [Safety Logic] > [SafetyApp] > [Logical I/Os]
> Editor window shows following options:
Tab
[Safe configuration]
[I/O mapping]
[Information]
>
Set the parameters of the logical device
The [Safe configuration] tab enables access to the parameter interface of the logical device. Number
and type of available parameters depend on the selected logical device.
Improperly set parameters can lead to undesired behaviour of the system.
► Familiarise yourself with parameters of the logical device before the configuration
(→ Logical devices for safe AS-i slaves
All time indications have an inaccuracy of +/- 1 PLC cycle time. The user can freely set the
cycle time of the device-internal fail-safe PLC within the defined limits.
► Note the set PLC cycle time for dimensioning the following parameters.

Stabilising time (StabilisingTime)

Synchronisation time (SynchronisingTime)

Tolerance time (ToleranceTime)
To configure the logical preprocessing of the logical device:
> Select the tab [Safe configuration] in the device editor.
> Editor window shows table with available parameters of the logical device.
► Enter the required parameter values for all displayed parameters in column [Value].
> Entered values are applied.
