Visualisation element neither displays text nor variable value (corrected from V3.12)
Corrected from:
PLC Designer V3.12
Response of the new version:
If a text variable used in a visualisation element is subject to unit conversion, the visualisation element will display the value the with the scaling defined in the unit conversion.
What happens? Elements on a visualisation page neither display texts nor variable values.
When does this behaviour occur? The behaviour occurs if the text variable used in the visualisation element concerned is subject to unit conversion.
Which products are affected? PLC Designer V3.9 and higher
Short-term measures: Do not use any variables with unit conversion in visualisation elements.
Evaluation/recommendations: The unit conversion is used to define conversions for variables in visualisation elements and IEC editors. I.e. via a visualisation element, the value of a variable is displayed with the scaling defined in the unit conversion. Due to this function restriction, the unit conversion cannot be used in visualisation elements.
