Integration in the control
The safety laser scanner communicates with the machine controller as follows:
•
I/O: local inputs and outputs (incl. OSSDs)
The safety laser scanner is available in variants with the following maximum protec‐
tive field range:
•
4.0 m

Connections
•
1 × connecting cable with male connector, M12, A-coded for voltage supply,
OSSDs and universal I/Os (can be used as universal input, universal output or in
pairs as static control input)
•
1 × female connector, USB 2.0 Mini-B for configuration and diagnosis
1)
An OSSD is a safety switching output. The functionality of each OSSD is tested periodi‐
cally. 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 analyzed
together.
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. Generally, at least 2 sepa‐
rate channels are used to do this.
A static control input is a dual-channel control input, which evaluates the status of every
channel as the value 0 or 1. The signal states of one or more static control inputs give a
unique signal pattern. This signal pattern activates a monitoring case.
Universal I/O can be configured as universal input or as universal output.
Depending on the device, a universal input can be used for resetting, external device
monitoring (EDM), sleep mode, or restarting the protective device, for example. If sleep
mode is activated by a universal input, the sleep mode must not be used for safety
applications. Certain universal inputs can also be used in pairs as a static control input.
The function of a universal output is configurable. Which functions are available
depends on the device. Possible signals are, for example: reset required, contamination
warning.
A universal output must not be used for safety functions.

The USB connection may only be used temporarily and only for configuration and diagnostics.
