Configure logical device
Configuration is made via the node [Logical I/Os] in the safety extension area of the device tree. All
safe local devices added to the project are listed there as sub-node.
To configure the logical device of a safe sensor at a local input channel:
► 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.
Incorrectly set parameters can lead to undesired behaviour of the system.
► Familiarise yourself with parameters of the logical device before the configuration
(→ Logical devices for the local I/O interface
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 device:
► Select the [Safe configuration] tab in the device editor.
> The editor window shows a table with available parameters of the logical device.
► Enter the required values for all displayed parameters in [Value] column.
> Entered values are applied.
