Dear sir,
I have SIMATIC S7-1200 and a Signal Generator Device and I use the NORM_X and SCALE-X functions in the TIA Portal program V 15 . The MIN value of NORM_X is 0.0 and the MAX is 27648.0 . It’s assumed that I use a RTD (PT100) with the Temperature Transmitter ranges ( -100 ˚C to 800 ˚C) and its output is 0-10 VDC. The output of NORM_X function is sent to two SCALE_X functions: one to scale the Ohms and the second to scale the temperature values.
I depended on the RTD Temperature VS. Resistance Table to get the MIN and MAX values for these two scale functions. The first scale function which is for Ohms the MIN value is -100 ˚C whereas the MAX is 800 ˚C and the MIN value for the second scale function is 60.26 Ω and the MAX value is 375.7 Ω ( Because -100 ˚C is equal to 60.26 Ω and 800 ˚C is equal to 375.7 Ω in the reference table).
But when I inject the following volt values in the Analog input of the PLC the output values of the Two SCALE_X functions are not as shown in the table?!
Examples:
1- At 2.5 V the output of the first SCALE_X function is 124.4141 ˚C and the output of the second SCALE_X function is 138.91 Ω but in the Reference table when the Temperature is 124 ˚C the Ohms must be 147.58 Ω.
2- At 5 V the output of the first SCALE_X function is 349.93 ˚C and the output of the second SCALE_X function is 217.9 Ω but in the Reference table when the Temperature is 349 ˚C the Ohms must be 229.36 Ω.
3- At 7.5 V the output of the first SCALE_X function is 575.488 ˚C and the output of the second SCALE_X function is 297.0111 Ω but in the Reference table when the Temperature is 575 ˚C the Ohms must be 305.63 Ω.
Why are the SCALE_X outputs not the same as what they must be as in the reference table?! And what must I do to make the outputs the same as what is shown in that table?!
Thank you and I’m waiting for your reply.

I have projet régulation of température pid with pt100 3 wires (condition=37°T constant) with bloc RTD (S7-1200) Can i help me plz ?

[@asifislam7376]

What's this max value may i know? 27648?

[@delciomassa]

Where can I find this datasheet?

[@JohnGvideo]

What kind of datasheet you mean ? :)
