Hello Stef_BevyzRenD, Do you mean AI7 or I7? I7 is digital input however your sensor is 0-100mV analog therefore you should connect to analog input module with resistor (which is 0-20mA input). Have a look at this link https://www.automation.siemens.com/tf/WW/en/Posts/463 Regards, |

Hi desmul24, I meant I7 but i assigned it to be analog input, so that makes it AI1 (logo 0bA7) |

the singal is very low . you have to use a converter similar to the weight converters/transmiter take a lok for an example http://www.laumas.com/trasmett_en.htm |

Your LOGO! support Analog value? You have a LOGO! 12/24 RCE 0BA7, correct? The + of your sensor output must go to an analog input of the LOGO. Di 7 is normaly the 1 Analog input, Ai1 De - of your sensoroutput must go to te - of the powersupply. LOGO! meassure 0-10 Volt in 1000 steps. 1 step = 10 mV so must see something on the LOGO!. Post your programm here Look in the example, it must work. Measure with a Voltmeter between Di7 (=Ai1) and - LOGO Powersupply AttachmentAnalog1.zip (198 Downloads) |
