how to product thermal Analog input

hi, im beginner of Simatic programing

i want my system take thermal analog input and analog output

i use these hardware

- CPU315-2 PN/DP(CPU)

- 6ES1 331-7KF02-2AB0(AI)

- 6ES7 332-5HF00-0AB0(AO)

- Fluke type K(Thermal change sensing)

- weigel pq72rs for thermal output

and i programing by step7 

i read manual and i think analog input maybe use fc 105 and output use fc 106

but i dont know what kind of stat in fc 105 hi limit and low limit

i take somekind of random stat in there for seeing perfect degree but all failed

please help me to solve this problem. i want my system sensing thermal perfectly and see result by degree meter.

how use FC105 block to read PT100 RTD feedback value

Hi landlandchicken,

Try to separe the problems.

1.- SCALE function for read the analog input, pay attention at the range of your sensor.  Then, you need to put these values on HI and LO.

2.- UNSCALE function, you scale from 0 to 50.0, but you equipment have an input 4-20mA from 0..100%.  So, If you want that element output have maximum value, you need to scale until 100%.
