SICK nanoScan3 I/O

Process
Y
ou define one or more sequences. You can use a sequence to map the sequence of
work steps for your machine.
In all sequences, you can define a maximum of two subsequent monitoring cases for
each monitoring case.
If you do not specify a subsequent monitoring case for a monitoring case, then any
monitoring case may follow.
Individual steps
Y
ou define individually for each monitoring case which one or two monitoring cases may
follow.
If you do not specify a subsequent monitoring case for a monitoring case, then any
monitoring case may follow.
Complementary information
Y
ou can use the changeover order as an additional check of your control unit. For exam‐
ple, deviations of a vehicle from the route or a plant from the prescribed production
process can be detected.
7.12.2 Several monitoring case tables
Certain variants of the safety laser scanner support several simultaneous monitoring
c
ase tables. For example, you can use a monitoring case table to switch between differ‐
ent monitoring cases with different field sets. At the same time, you can use another
monitoring case table to keep a monitoring case always active with a particular field
set.
Even if you use several monitoring case tables, each shutdown path is assigned to only
one monitoring case table.
If you use several monitoring case tables, one monitoring case must be active in each
monitoring case table at all times. As long as no monitoring case is active in a monitor‐
ing case table after the start, all outputs remain in the OFF state and the device dis‐
plays Waiting for inputs. If no monitoring case is active in a monitoring case table during
operation, all outputs switch to the OFF state and the device displays a fault.
7.12.3 Settings for monitoring cases
Name
In t
he Name field, you can enter a meaningful name for the monitoring case. If you cre‐
ate a lot of monitoring cases, you should consider a naming concept that makes it pos‐
sible to identify the monitoring cases easily (for example right cornering, left cornering).
Standby
If you activate this option, the safety laser scanner changes to the passive state as
soon as the input conditions for this monitoring case exist.
7.12.4 Input conditions
For each monitoring case, you choose the input conditions for which the monitoring
c
ase will be activated. The relevant monitoring case is activated for exactly this combi‐
nation.
Combinations which are invalid or already assigned are marked.
