Hello. Use I_R, then DIV and MUL FB's. Divide by 27648, multiply by 400. |

No matter what do you do first: divide or multiply, the result will be the same. |

Hello. For S7-300 AI modules and temperature sensors usually you should divide AI value by 10 or 100 depending on temperature sensor type. Look at the manual, chapter 5.1. |

AI value DIV by 27648, MUL by 180, minus 30 (SUB FB). |

And if my range is -50 to 250. So first MUL by 300 and SUB by 50? |

OK. I don't know which type of Knick device you are using, don't know its technical data and wiring. |

Check Knick configuration with DIP switches S1, S2, S3 and proper wiring. |
