17 Glossary
CoLa2 CoLa2 (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.
Contour detection field The contour detection field monitors a contour of the environment.
The 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
t
he 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,
which 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).
Electro-sensitive protective
de
vice
An electro-sensitive protective device is a device or system of
devices for safety-related detection of people or parts of the body.
It is used to protect people from machines and facilities that pose
a risk of injury. It triggers the machine or facility to adopt a safe
state before a person is exposed to a hazardous situation.
Examples: Safety light curtain, safety laser scanner.
ESD Electrostatic discharge
ESPE Electro-sensitive protective device
