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. |

@KSN sir We are using temperature switch which can provide 4-20mA output signal. Please describe me once how can I use this value to a actual value? I didn't understand what in manual that is why I have used my question in forum. |

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

Means mean if range is 0-350 so I can MUL by 350 right? |

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