3.2.3
Test input
The sender has a test input that can be used to switch off the light beam of the sender
and thereby simulate an interruption of the light beam.
The test input is provided for the purposes of checking the functioning of the sender
and receiver. When used in combination with an external test device to evaluate the
test results, the protective device is suitable for safety applications.
3.2.4
Cascading
Cascading allows up to 4 single-beam photoelectric safety switches to be connected in
series.
3.2.5
Application diagnostic output
Overview
An application diagnostic output can be configured on pin 2 of the system connection
of the receiver via IO-Link.
The application diagnostic output will signal a specific status of the protective device
depending on the configuration.
The status of the protective device is indicated via the yellow status LED.
Output signals
The following signals can be outputted via the application diagnostic output:
•
Alarm
When Alarm is configured on the application diagnostic output, the application
diagnostic output signals when the protective device is only partially operational,
for example if the sender or receiver is contaminated or poorly aligned.
•
Health
When Health is configured on the application diagnostic output, the application
diagnostic output signals when the protective device is only partially operational,
for example if the sender or receiver is contaminated or poorly aligned, or the
cable is damaged.

3.2.6
IO-Link
Overview
The protective device is IO-Link capable.
The IO-Link communication between the protective device and a PC can occur via an
IO-Link master. To do so, connect the IO-Link master to the system connection of the
receiver, and via a USB cable to a PC.
The connected protective device can be configured, or data exchanged or transferred
using the SOPAS ET configuration software.
Data exchange and configuration
The following data, for example, can be exchanged or transferred via IO-Link:
•
Device information
•
Quality of reception
The following functions, for example, can be configured via IO-Link:
•
Switching output
•
Application diagnostic output
