Which products are affected?
ESP-HMI1-P (HMI Designer Version 1.x)
What happens?
The keypad shows the rounded value of a code. This means, the value shown by the operating unit is not identical with the code value, e.g. the keypad does not show the code value 0.05 but the value 0.049999.
When does the problem occur?
In the HMI Designer the project component
Variable defines the codes of the drive controller which are to be visualized. In the register
Limit values the value of the variables can be scaled through the fields of the
Linear correction.
It may be possible that the keypad shows a rounded value instead of the exact code value if
- the value of the variable is scaled by means of the Linear correction and
- the numeric format 'Floating Point' is set for the display field on the page.
Possible diagnostics?
None.
Short-term measures/recommendations?
Please consider the following for the definition of variables in the HMI Designer:
- Do not enter negative values in the fields for the Linear correction under the register card 'Limit value'
- Enter values as low as possible in the fields of the Linear correction (determine the smallest common denominator for the scaling). High values can lead to an overflow during scaling.
If possible please use the
numeric format 'Integer' for displaying code values. In this case decimal codes can be displayed in the fixed point format.
Evaluation:
Due to this function restriction rounded code values may be indicated. The input of values via keypads is not affected by this function restriction.
