Hope I can find help from the community. I have the following problem:
I have a template where there are a few components. These components take their value from an expression. If a certain condition is true then the value comes from an OPC Tag, otherwise the value becomes itself (last value).
I used some of this template in a window. The problem is that when I start a client and the condition (for the component value) is false, then I have a problem with the data quality until condition becomes true and components take the value from the OPC tag. (I suppose it is like it has a null value at the beginning but I believed the first value is the value that it has in the properties tree in the designer)
The question is:
How can I fix the components quality (give a fixed value or take the last value from historical for example) until it takes the correct value?
Thanks in advance!
