Here's my test setup.

This is what I put in the first function node...

> var max = 50;  
> var min = 20;  
> var data = 30;  
> msg = {payload:data,ui\_control:{min:min,max:max},topic:"Soil"};  
> return msg;

The second function node is the same but with different values for max, min and data.

Hope this works for you.
