Hi all, I am using the PLC ET 200PRO (IM 154-8 PN/DP) with TIA Portal V15.1 and I am trying to read a value at the analog input but unfortunately this doesn't work. My values range from 0.8 V to 3.5 V and I used the functions NORM and SCALE (I don't have NORM_X and SCALE_X). I measured at the input and the voltage is there, but when I go online, I don't see any values at the input. Then I don't know if I parameterized the inputs wrong or if it's a hardware problem. For the connector I only connected the pins U+ and U-, which should be enough. In the attachment you can find some photos. Thanks in advance :) AttachmentAI_U.pdf (218 Downloads) |

Hi, I always read the 0 V. And yes, I was changing the value of my input voltage, I ranged from 0 to 10 V and still only continued to show 0. |

Instead of IW304, check IW304:P - maybe the address is outside the process image. |
