0BA8 AM2 module sensor calibration

Hi,

do you know the right AI number of the AM2?

How to get the right number:

Practical way:

1. press up/down button on LOGO! till date&time is shown on the LOGO! display.
2. press cursor left/right till the AI is shown.

Now check if you cna ge th evalue on the AM2 what is the AI number where the value is changing.

Theoretical way:

In LOGO! SOft Comfort open file/Properties adn change to I/O Settings. If 0 AI are enabled for the BM, then AI1 & AI2 is the right number for the connected AM2

If 2/4 is activated on LOGO! BM, then the right number is 3&4/5&6 for the connected AM2.

Hope this helps

Which temperature range correspond to the 0-10V?
Which amplification factors are parameterized?
How is the offset set?

Which temperature range correspond to the 0-10V?

Without knowing what the measuring range of the sensor is, one can not give any information.
So, what do the 0-10V in the transmitter's output correspond to?
0-10V = 0 to 100 ° C?
0-10V = -30 ° C to 70 ° C?

Without this, no one can tell you what the values displayed in your screenshot correspond to what temperature.

For a measuring range of -10.0 ° C to 110.0 ° C, the measuring range is 120.0 ° C.
The analog input of the LOGO! converts the 0 to 10V into 0 to 1000 units. For the span of 120.0 ° C, 1 unit equals:
120.0 ° C: 1000 = 0.12 ° C.
This corresponds to a resolution of 0.12 ° C.

Thus, at AI1 = 312 units = 312 * 0.12 ° C = 37.44 ° C. Now the offset of -10.0 ° C has to be considered:
37.44 ° C + -10.0 ° C = 27.44 ° C, in the LOGO! Display would be 27.4 ° C (with a gain of 1.2 and one decimal place.
You have chosen a gain of 0.12 in the analog amplifier B012, without decimal place. That's why in the screenshot on B012 you will see a real temperature of 27 ° C.

In attachment a screenshot, as it looks in the simualtion, if a gain of 1.2 and one decimal place is Chosen.
