In function block programming I am wanting to be able to select from 4 different flow meter tags to point to an equation depending on the mix tank we are using. I will add this discrete select button in Wonderware.

I tried setting this up with the SEL function and I can toggle between two tags but for the enhanced SEL I am not sure what its looking for and how to setup multiple tags and be able to select using a discrete. Once selected it will wire to a math equation I am using for ratio.



Thanks
Rich

With the ESEL, you don't select with a discrete. You use the ProgSelector input when under program control. Send it 1 through 6 to pass through inputs 1 through 6. Set it to 0 to make no change in the output.
