Hello, It is hard to decipher you requirement but I guess you are looking for scaling block (FC105) for converting a field value in range of 4~20 mA to an equivalent floating point value.Search the forum for numerous tips and samples regarding this function plus online manual of STEP 7. After conversion, you may need processing the value by comparators. Good Luck!fc105FC105 - Analog Scalingfor a totalizer, also read more HERE. Hamid Hosseini |

Hello again, To have references on AI/AO hardware point of view , how to wire and setting for different options.You can read more Here for S7-300 range of products. Then you have option of using drivers in PCS 7 to read/write from/to channels.In STEP 7 , you can use the concept of process image or in some cases direct access to peripheral addresses.I suggest Programming With STEP 7 fo rmore reference or agetting started manual for PCS 7.
But I believe the fast and reliable way of quick start would be SITRAIN program world wide. I hope this helps, Hamid Hosseini |
