7.13.1.1
Configure switching sequence
Overview
You can specify the order in which the monitoring cases can be called.
You can specify one or two subsequent monitoring cases for each monitoring event.
If you do not specify a subsequent monitoring case for a monitoring case, then any
monitoring case may follow.
If input conditions are present that do not call up any of the defined subsequent
monitoring cases, the safety laser scanner switches all safety outputs to the OFF state.
You can specify the order of the monitoring cases as a process or in individual steps.
Process
You 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
You 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
You 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.
7.13.2
Several monitoring case tables
Certain variants of the safety laser scanner support multiple simultaneous monitoring
case tables. For example, you can use a monitoring case table to switch between
different 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
monitoring case table after the start, all outputs remain in the OFF state and the device
displays
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 an error.
7.13.3
Settings for monitoring cases
Name
Enter a name which is as descriptive as possible for the monitoring case in the
Name
field. If you create a lot of monitoring cases, you should consider a naming concept that
makes it possible to identify the monitoring cases easily (for example right cornering,
left cornering).
