Q1 output
The Q1 output is purely a switching output. In addition, the output serves as a commu‐
nication line for bidirectional data transmission when using the IO-Link interface.
The Q1 output of the OD 1000 provides the following switching modes:
•
DtO, distance to object (1-point), one switching point
•
Window, two switching points
•
ObSB, object between sensor (device) and background, one switching point
•
Alarm (only in
Advanced
user level)
•
Signal level warning (only in
Advanced
user level)
•
Edge height change (only in
Advanced
user level)
The switching modes are explained in the subsequent chapters.

Notes on the measuring and setting functions
The following functions can be set independently from each other on both outputs
depending on the selected output function.
Delay mode
Delay mode is used to output the output state change with a time delay or as a short
switching pulse (1 shot).
