The problem is:

The LOGO! works only with integer values, it does not recognize real numbers.

There is a float to integer building block that converts 32 bit float values to 16 bit integer values.
And then there are the limits.
Float value 32.767 is still accepted, then appears as integer value 32767 (maximum).
Float value 32.768 is still accepted, but then appears as an integer value of 32767 (maximum) because the value is limited to 32767.

At the eAq output (more specifically), the LOGO! larger float values are also displayed, but without decimal places.
Example:
14568.356 will then show 14568356.

Without knowing exactly which values you want to transfer to the LOGO!, unfortunately I can't tell you anything more precise.

Thanks :)

I want to transfer real sensor process values from S7-1200 (TIA Portal) to LOGO!.

That have I understand.

But you have not understand me.

Which value have the real variables?
How many decimal places?

They are temperature sensors, the value range between 15.0-40.0 deg-C, one number after the decimal dot.

Sorry if I misunderstand it

 No problem, but it had to be clarified. 

The easiest way is when the LOGO! is the client.

Here's a link to a Siemens application for this way:

LOGO! - S7 Connection with LOGO! Client and S7-1200/1500 Server
