Helo , i have logo 8 , i added an analog extension module to it to ready a 4-20 mA pressure sensor , the pressure sensor is installed on the bottom of the tank . the purpose of the pressure sensor is to measure the pressure and i will convert the reading to the level of the liquid in the tank . the sensor is from 0-2 bar and the tank is 7 m hight and 1.8 m width . is that possible ? if no why ? and if yes can you support ------------------------------------------------------------------------------------------ |

With this height (7m) it seems to be a standing object, cylinder, quader or anything else. If you just want to know the height, then use example in attachment. If you also want to display the volume, then we need the exact dimensions of the tank. Regards, Scorp AttachmentTank1.zip (303 Downloads) |

I have changed the program with additional Liter display. The negative values are okay without sensor, because the sensor begins with 4mA / 0bar and without sensor it is 0mA / <0bar. The program is presetted with 0 analog inputs on the base module, because you have a AC230V version without analog inputs. Therefore the first analog input of the AM2 module should be AI1. If you are asked for overwriting the AI settings, then click yes. Otherwise your analog input is numbered to AI3 or AI5 and on AI1 you don't get the value.
