Hello everybody, I work with the newest LOGO with V8.3 and a Logo TDE I have a laser sensor, an stepper motor. For the moment, I can read the distance of the sensor on my display. I can also count up and down with F1 and F2. And my engine works with Q1 and Q2 ( already have a motor controller) If I press F1 (count up) the engine schould go to the value that i set up on the TD, and the same value as the laser sensor. If I press F2 (count down) the engine should go to the right to the value that i set up on the TD and the same value as the laser sensor. Example: If I count on the LOGO TDE untill 500mm (max value 3100mm), the engine should go to 500mm and stop. I can read distance with the laser sensor. Can some one help to change my program?

4 mA = 0 mm and 20 mA = 3800 mm? |

Okay, so what do i have to change? B012 and B002 only the settings or do I have to take another function block? the sensor is the sick WTT12L-A2563 my excuses it is 100-3800mm distance range, 4-20mA Attachmentlasersensor sick.pdf (513 Downloads) |

I would scale as in the attachment, with two analog amplifiers connected in series. With an analog amplifier, no correct values are obtained at 4-20 mA and a measuring range of 100-3800 mm. The first analog amplifier converts the 4-20 mA into 0-1000 units, the second analog amplifier then converts the 0-1000 units into the measuring range of 100-3800 mm.
