Hi Duccio, I hope I understand what you want... BTW: What library are you using? Classic library or APL? Anyway, both libraries can have the Namur limit adjusted. I can't remember what the variable names are in classic, but in APL they are as follows: When you are using the Pcs7AnIn driver block, you can adjust the Namur limit settings for 4-20mA signals. Namur is a standard for defining signals. The Namur default limits in PCS7 are set to 3.6ma to 21mA. If a signal is below or above the limit, a Bad signal occurs. You can adjust those limits by yourself on the Pcs7AnIn driver block: Variable: "NamurOff" must be "1" and then you can adjust the limits at variables: "HighLimit" and "LowLimit". In the classic library the Namur limit can be adjusted, but the variables are named a little different. I hope I understand you correctly, and I hope this helps you! |

Hi Duccio, I understand what you mean now. The Pcs7AnIn does not have a setting to change the raw values. However, it is possible to obtain the electrical input of the analog input module by setting Scale.High the same value as Scale.Low. Or you can get the raw input value by setting Scale.Low to "0" and Scale.High to "1". |
