hi MIDO, you don´t have to scale anything. The value in the AI is already the temperature in 1/10(standard). Table A- 181 Representation of analog values for resistance thermometers PT 100, 200, 500, 1000 and PT 10, 50, 100, 500 GOST (0.003850) standard SIMATIC S7 S7-1200 Programmable controller hope this helps, regards, |

Hi I read the instructions carefully. However, I am not able to read a reasonable temperature. I lack to the professional experience to address the correct limits for the program( pic attached). Yes, I got readings. but this reading is still meaningless. in table Table A- 181, I used the limits for PT1000 (min 850, max 10000) instead of (o to 27648) without any valid effect. May you advise me what limits should I use for NORM_X & SCALE_X
