3.3.5
A field set consists of one or more fields. The fields in a field set are monitored
simultaneously.
A field set can contain different field types, e.g., a protective field and a warning field.
A typical application is the use of a protective field with one or more warning fields: if a
vehicle approaches a person, a warning field triggers an optical or acoustic signal. If the
person does not react to this and the vehicle continues to approach, the safety laser
scanner detects an object in the protective field and switches the associated safety
outputs to the OFF state. The vehicle stops before it reaches the person.

3.3.6
A monitoring case signals the machine status to the safety laser scanner. The safety
laser scanner activates the field set, which is assigned to the monitoring case and
therefore a particular machine status.
If a machine, e.g., has various operational statuses, a monitoring case can be assigned
to each operational status. The safety laser scanner receives a defined signal for the
current operational status via the safety-related network. If there is a change of signal,
the safety laser scanner switches from one monitoring case to the monitoring case that
is assigned to the new signal (as well as the new operational status). Generally, one
field set is assigned to each monitoring case.
