Sensor state
Sensor status byte
uSensorState
contains the following information:
Logic
Sensor status byte
uResultEdge/Logic
contains the following information:
the high nibble (bits 7 … 4) contains the
Object Point/EAW State
for all four EAWs; the low
nibble (bits 3 … 0) contains the
AW Logic Analysis Depth
state for all four EAWs.
Object detection
Sensor status byte
uResultAWs
contains the following information:
the high nibble (bits 7 … 4) contains the object detection state of the four AWs; the low nibble
(bits 3 … 0) contains the object detection state of the four EAWs (see "Current Status" under
"Analysis Window Definitions" on page 79).

Meaning
7
ErrM
Error mode, permanent sensor malfunction
6
Cmd
Command mode: the sensor is in command mode. The queries from the control are not processed
and the measurement data are frozen (indicated by the constant scan number).
5
Menu
Menu mode: the sensor is operated by the user via the display/key pad. The queries from the control
are not processed and the measurement data are frozen (indicated by the constant scan number).
4
Meas
Measure mode: the sensor is in measure mode.
This is the normal operating state in which the maximum measurement rate is attained.
3
ErrF
Error, permanent sensor malfunction.
2
WarnF
Warning, temporary sensor malfunction.
1
Active
Sensor activated.
0
connect
Sensor connected via Ethernet.
