Reading double floating point in Scada Program

Dear Mr. Black,

I looked through code that you directed me and I think it is not a good way to read a lot of data from 300 energy analyzer in a site. You know that scada program always run this code to read active and reactive energies for every analyzer in one cycle. This means that scada program has to run this code 600 times in one cycle.
Is there any different (more efiicient) way to read this type of data from any device.

Thank you.
