Data source
•
R
ead from device: Only available when a device is connected. The data stored in the
device will be read.
•
Load file: You can open a file that stores events that were previously read from a
device.
•
Store data: You can save the events read from a device to a file for later analysis.
Events
T
he Events view shows a graphical overview of the object detections in safety-related
fields that have led to a safety output switching to the OFF state.
•
Navigation: You can select the event whose measurement data is displayed in the
right area.
•
Overview of events: The position of each recorded object detection relative to the
safety laser scanner is displayed. If you hold the mouse pointer on a position, the
set multiple sampling is displayed. When you click a position, the corresponding
measurement data is displayed in the right-hand area.
•
Measurement data for the selected event: The measurement data of the selected
object detection is displayed. If multiple scans are stored for the selected object
detection, you can view the individual scans one by one by clicking the icons next
to Scan.
Event table
T
he event table shows detailed information about the events which have led to a safety
output switching to the OFF state.
Based on the measurement data, a probable cause is assigned to each event:
•
Object: An object was probably detected in the protective field.
•
Contour: A reference contour field or a contour identification field has been inter‐
rupted.
•
Contamination: The shutdown was triggered by a contamination of the optics cover
in the area of the protective field.
•
Glare: The shutdown was triggered by an external light source in the scan plane
in the area of the protective field, e.g., sun, halogen light, infrared light source,
stroboscope.
•
Close to field edge or particle in field: Object detection in the protective field was
probably triggered at the edge or by particles.
Multiple sampling
T
he Multiple sampling view shows how often object detections with different durations
occurred. All object detections in safety-related fields are taken into account. Therefore,
the number of entries in this view may deviate from the other views.
The duration is specified as the number of consecutive scans in which an object is
detected in the field. For each duration, the diagram shows the corresponding number
of object detections.
