EtherNet/IP EtherNet/IP™ (EtherNet Industrial Protocol) is an Ethernet-based
ne
twork used in industrial automation.
EtherNet/IP™ implements the CIP™ (Common Industrial Protocol)
based on the Ethernet and TCP/IP protocol family.
EtherNet/IP™ with the CIP Safety™ protocol extension is also suit‐
able for safety-related data communication.
Field set A field set consists of one or more fields. The fields in a field set
ar
e monitored simultaneously.
A field set can contain different field types, e.g., a protective field
and a warning field.
Hazardous area Hazardous area is any space within and/or around machinery in
whic
h a person can be exposed to a hazard. (ISO 12100)
Monitoring case A monitoring case indicates the machine status to the sensor.
Generally, one field set is assigned to each monitoring case.
The sensor receives a defined signal for the current machine
status. When a signal change occurs, the sensor activates the
monitoring case and thereby the field set that is associated with
the new machine status.
OFF state The OFF state is the status of the outputs of the protective device,
wher
e the controlled machine is triggered to quit its dangerous
state and the start-up of the machine is prevented (e.g., the volt‐
age at the OSSDs is LOW, so that the machine is switched off and
remains still).
ON state The ON state is the status of the outputs of the ESPE, where the
controlled machine is permitted to operate (e.g., the voltage at the
OSSDs is HIGH so that the machine can run).
OSSD Output signal switching device: signal output for the protective
device, which is used for stopping the dangerous movement.
An OSSD is a safety switching output. The functionality of each
OSSD is tested periodically. OSSDs are always connected in pairs
and must undergo dual-channel analysis for safety reasons. An
OSSD pair is formed from 2 OSSDs that are connected and ana‐
lyzed together.

Protective field The protective field is the area in which the test object specified
b
y the manufacturer is detected by the electro-sensitive protec‐
tive equipment (ESPE). As soon as the electro-sensitive protective
device detects an object in the protective field, it switches the
associated safety outputs to the OFF state. This signal can be
passed to controllers resulting in the dangerous state coming to
an end, e.g. to stop the machine or the vehicle.
Reference contour field The contour as reference field monitors a contour of the environ‐
ment. The safety laser scanner switches all safety outputs to
the OFF state if a contour does not match the set parameters,
because, for example, the mounting of the safety laser scanner
has been changed.
National and international standards require or recommend that a
reference contour is monitored, if the safety laser scanner is used
in vertical operation for hazardous point protection or for access
protection.
