Energy Display Scripts Outline

1. Java scripts harvest data directly from Modbus
2. Perl scripts collects this data and put it in the Postgress database "energy" under the table "electrical_energy"
   • electrical_energy attributes:
     • area - what building.
     • preal - kW hours for that instant.
     • date - date of harvest.
3. A final perl script (display/production|development/js-file-gen.pl) accesses this data and generates a .png graph using the Google graph API
   • This script takes one parameter for either the production or development branches.
4. The images generated (day, week, month, year) are put in a html frame on a page to display the data.
   • This page refreshes every 5 minutes
