Display float value

[vy.nguyenthanh@biendongco.vn]

Hi everyone, I'm using WinCC OA 3.16 P014 I have a problem when I display float value from a dpe connected to a tag (datatype real) of PLCSim and the value of this tag is 20.8, my textfield display 20.799999237061 but when I disconnect with the tag of PLCSim and enter value in datapoint parameterization, the value displayed on textfield is 20.8

If you want to limit the number of digits after the comma for a float value received from the PLC you can use the message conversion config with the option "Adjustable accuracy".
Limiting the precision of the float value is also necessary if you want to use smoothing of float values.
