NOTE!!
The multipex mode is not available in IO-Link mode.
Description of multiplex mode To change to multiplex mode, sensors must be interconnected via
PIN 5 (MF) and different addresses must be assigned to them using the
software.
In multiplex mode, all sensors measure in alternation in a defined
sequence. This operating mode prevents unwanted mutual interference
since measurements from different times cannot be incorrectly compared
with one another. The sensors can therefore be mounted without taking
into account mounting distances.
Thanks to alternating measurement, the monitoring of large areas is
possible with additional position detection of recorded objects.
The detection zone is enlarged to a size which covers all connected
sensors. A maximum of 20 sensors of type UM18-2 Pro can be connected,
and they can also be combined with synchronizable SICK ultrasonic
sensors from other product families.
Since measurement by the sensors is done in alternation, the response
time of the total system is increased in accordance with the “overall
response time” formula.
NOTE!
For multiplex mode, you must assign a unique address to
the sensors. The "C Adapter" and the associated
software is required for this (order no. 6037782)
