Problems with analog proces.

Hi all

I have some problems processing analog values. When i test in the simulation mode everything works perfect, but when i download it and test the program it doesn,t.

Here are the problems:

If you open this printscreen you see an analog input A3 (pt100), B134 is the analog amplifier to convert to temperature. next i have B213 that simply sets an offset because there is a little bit of difference between real temperature and logo temperature.

The strange thing that happens is with B141 the analog comparator. When you look at the Ax-Ay parameter underneath B141 is has the value 361. how is that possible when the input is only 353, you see this value there. Ax-Xy should be the value 353 because Xy = 0.

Is there something that misinterpreted?

Here you see a simple test. B124 is a mathematic instruction. On the left you see the situation in simulation, there is a value P1 is 348 that i can put there from message text. you also see that the parameter Aq is 348 so i can use this value elsewhere.

Now when i download that program and test online, you see the situation on the right side. The P1 value is still 348 but the Aq parameter is set to 0.

Why is that? Why is there a difference between simulating and online test?


Thanks in advance
