No.

In LWE there is not possible to make a decimal Point by analog values.

In my eyes a very big drawback.

The only possibility that I see is the change of unity, from bar to mbar.

For example, you have a sensor 0-10 bar and in the LOGO! Scaled as a value with 2 decimal places, ie 0.00 - 10.00 bar (0 - 1000 units).
Multiply the value by 10, then it's 0 - 10,000 units. This can then be displayed in the LWE as 0 - 10,000 mbar.
