17 Glossary
CoLa2 CoLa2 (Command Language 2) is a protocol from SICK, with
whic
h a client (control, computer, etc.) can access suitable SICK
sensors via a network (TCP/IP) or USB.
Collision protection field The collision protection field detects oncoming industrial trucks
in narrow aisles based on the reference target. It has a greater
scanning range than a protective field. With the collision protection
field, collisions of industrial trucks in narrow aisles can be safely
prevented.
The collision protection field is not suitable for detecting people.
The collision protection field may only be used in narrow aisles.
Conical error In practice, the area scanned by a scan plane is not precisely
f
lat but rather slightly conical. The conical error indicates how
pronounced the conicity is, i.e. how strongly the scanned area
deviates from the ideal plane.
The conical error of a particular device is invariable. It can only be
compensated for by measures during mounting.
Contour detection field The contour detection field monitors a contour of the environment.
T
he electro-sensitive protective device switches the associated
safety outputs to the OFF state if a contour does not correspond to
the set specifications, e.g. because a door or flap is open.
Control input A control input receives signals, e.g. from the machine or from
the control. Use of control inputs is how the protective device
receives information about the conditions at the machine, e.g., if
there is a change of operating mode. If the protective device is
configured appropriately, it will activate a different monitoring case
after receiving a new control input.
The control input information must be transmitted reliably. Gener‐
ally, at least 2 separate channels are used to do this.
Depending on the device, a control input can be realized as a
static control input or a dynamic control input.
Dangerous state A dangerous state is a status of the machine or facility, where
people ma
y be injured. Protective devices prevent this risk if the
machine is operated within its intended use.
The figures in this document always show the dangerous state of
the machine as movement of a machine part. In practice, there
are different dangerous states, such as:
•
Machine movements
•
Electrical parts
•
Visible and invisible beam
•
A combination of multiple hazards
Dynamic control input A dynamic control input is a single-channel control input that eval‐
ua
tes a number of pulses per time. An incremental encoder can
be connected to a dynamic control input. The incremental encoder
reports, for example, the speed of an AGV. In conjunction with a
second control input, a dynamic control input is used to switch
between different monitoring cases depending on the speed.
EDS file An electronic data sheet (EDS file) is a text file in ASCII format,
whic
h describes the properties of an EtherNet/IP device. Certain
software programs for configuring devices and networks can inter‐
pret EDS files.
The configuration software of some safety controllers does not
support the connection of safety modules with an EDS file (unlike
with non-safe modules).
