PNBC006 WENGLOR DISTANCE LASER SENSOR RPi interfacing trouble

AZ87

Anybody has an idea on how to read the measurements made by an industrial sensor using a raspberry pi??? I've already posted the same question somewhere in the forum but did not get any answer, so i thought Ive posted in the wrong place and here I am; first of all please don't judge me and HATE me if my question may sound ridiculous to you, i am a complete newbie to this field: i need to get the readings of this sensor through rasberry Pi and i have no clue; it is a  Wenglor PNBC006 Laser Distance Sensor and after many many days hunting on the web, i came across some documentation stating that this industrial sensor supports 2 type of connections: an M12 8pin cable AND an Ethernet cable. I figured out i can just connect it through an industrial Ethernet switch and make the communication with raspberry pi through the ETHERNET plug on it; from the official docs of Wenglor I can access the sensor settings and configuration panel through the IP address (which is provided) with a normal browser. My dilemma and biggest trouble is HOW DO I READ THE VALUES OF THE SENSOR WITH RASPBERRY PI? PLEASE HELP ME OR POIT IN THE RUGHT DIRECTION

MQNY THANKS Pray tone5

    Hi,

    You've double-posted, once in "EAGLE CAD" which makes no sense.

    That sensor cannot interface directly to the Raspberry Pi. The sensor has an analog interface, and the Pi doesn't.

    You mention using Ethernet, and it has a web server, so you can open up a web browser on any PC (doesn't have to be a Raspberry Pi for your initial test, it makes no difference) and observe the sensed value, but it will likely update at a much slower rate that way, so you may be waiting forever to scan the tire width that way.

    For the analog interface (which is your only real choice if you want a practical speed) you'll need a converter, for instance this device (I've not used it): ncd.io/.../
    You'll also need to write some code or look for demo code for whichever specific 4-20 mA receiver you use, hopefully the manufacturers of those will provide you with some sample code.
