I found the solution
+24VDC----sensor+ ------- sensor- --------4k9ohm-----0VDC
before 4k9ohm wire to input PLC and this works perfect.
Thanks anyway for your help.

Actually my real question is, if I connect following wiring to the PLC I have a signal but this signal never changes.
Maybe my inputcard or my plcprogram has a to slow cycle to update his status.
DC motor with Hall effect sensor.
This sensor should be used to position the motor .
Can somebody help me how to read this signal .
Motor has 4 wires
- 2 wires for 12V DC input to start/stop motor
- 2 wires sensor positive, sensor negative
Our goal is to read this signal of the sensor...
