I’ve successfully completed the task by adding this 2 transformations.
The first one reduces de series data to the last value received.
that gives me 2 columns, FIELD NAME and VALUE, field name is the name of each one of my motors and then value has the last value received so I can sort fields based on value.
Anyways, thank you for your help, Now I see that I have to learn how to use al those transformations.
