SICK scanGrid2 I/O

The input conditions indicate for which combination of input signals a monitoring case
is ac
tivated. When you add a monitoring case, a new combination is automatically set
as the input condition.
Cut-off paths
Each monitoring case has two cut-off paths. The cut-off paths switch different outputs
when the active field is interrupted.
•
Cut-off path 1: OSSD pair
•
Cut-off path 2: Universal output
Cut-off path 1 automatically switches the OSSDs. The output for cut-off path 2 is
deactivated by default.
You can activate the universal output for cut-off path 2 using the Uni-O checkbox at the
end of the monitoring case table. You also need to assign the signal Monitoring result to
Uni-O on the Inputs and outputs, local page (see "Inputs and outputs, local", page 53).
Sleep mode
T
he safe multibeam scanner can be put into sleep mode to save machine resources.
The sleep mode is assigned to a monitoring case and can then be activated via the
controller.
In sleep mode, the following restrictions apply:
•
OSSD pair permanently in the OFF state
•
No thorough check of the protective fields and warning fields
°
No object detection
°
No distance measurement
•
No update of the contamination information (front screen)
The Uni-O universal output is in the configured normal state during sleep mode (no
active signal):
•
Hi setting: The Uni-O universal output is in the LOW state during sleep mode
•
Lo setting: The Uni-O universal output is in the HIGH state during sleep mode
The following functions continue to be active in sleep mode:
•
Communication via USB and NFC
•
Processing of the static control inputs
Field Sets
T
he field sets that have been created are listed in the Field sets area.
You use drag-and-drop to assign a field set to a monitoring case. The fields in a field set
are arranged in the monitoring case as they were drawn in the field editor.
Protective fields are allowed for the safety-related cut-off path 1, and warning fields can
be used for the non-safety-related cut-off path 2.
You can cancel the assignment by dragging a field set from a monitoring case onto the
trash can symbol.
Defined cut-off behavior
In a
monitoring case, you can assign a defined cut-off behavior to a cut-off path
instead of a field:
•
Always OFF: If the monitoring case becomes active, the cut-off path is always in
the OFF state.
•
Always ON: If the monitoring case becomes active, the cut-off path is in the ON
state.
