Choose Cluster Element by user

[Meisspa]

Hi,

I have a simple problem but I find no simple solution. I have calculated data elements (DBL) and stored them into a cluster. Now I want to write a selected element to a 4-20 mA current output. The user should choose the cluster-element  by a DropDown-menue for each current output. Of course I know that I can use a ENUM and a CASE-function but that is not dynamical and for switching between 30 variables a little boring to code. Has someone a better idea to solve that problem?

Best regards,

Paul

If you have all the cluster elements as DBL only then you can convert them into array. Use a Ring control to index them if you want the user to select which variable.

Thank you! Simple solution! Do you have an idea how I can use the variable names instead of the RING-Index for selection? It would work of course by the numbers but the variable names would be much more comfortable!

Best regards,

You can add the variable names by editing the Ring control and when you select a variable you will get the corresponding index.
