QR code
A QR code as well as the corresponding web address are located on the safety sensor.
At the web address, you will find device information and error messages after scanning the QR code with a
mobile end device or after entering the web address.
When using mobile end devices, mobile service charges can accrue.

Connection technology
The transmitter and receiver feature an M12 connector as an interface to the machine control with the fol-
lowing number of pins:

Host devices are also equipped with an interconnection cable, 400 mm long, with M12 connector for con-
necting Middle Guest or Guest devices.
Middle Guest devices are equipped with two interconnection cables, 400 mm long, with M12 connector for
connecting Host or Guest devices.
Guest devices are equipped with an interconnection cable, 400 mm long, with M12 connector for connect-
ing Host or Middle Guest devices.
3.2.1
AS-i parameter port
The parameter port can only be addressed by the bus master. The MLC 510/A receiver delivers a safety at
work-specific code sequence which the AS-i safety monitor teaches in and permanently monitors. Further-
more, the bus master is able to read the interfering signal via the parameter port.
3.3
Cascading
To implement linked protective fields, up to three MLC safety light curtains can be cascaded one after the
other.
Adjacent protective fields, e.g., for stepping behind protection, can thereby be implemented without any ad-
ditional expense for control and connection. The host system performs all necessary processor tasks, pro-
vides indicators and the receiver-side interfaces to the machine and command devices.
Devices with different resolutions can be combined.
With mounting brackets (see chapter 15 "Ordering information and accessories"), an L or U-shaped fixed
connection can be created.
