The Global Data (Publish / Subscribe) utility is a powerful function incorporated into
the NOE product line. Implementing Global Data requires a configuration that spans
many PLCs throughout the system. Therefore, we recommend preplanning your
installation before implementation. Work spent on preplanning saves time and
money by reducing errors and unnecessary debugging time. Preplanning also
serves as an aid to ensuring consistency throughout the system.
Go to paper before computer.
We offer the following table to help with your system planning. The table below is a
graphic representation of a recommended configuration table for system planning,
which we call the Global Data Planning Spreadsheet. You may create your own

table using the format below or you may download a Microsoft ExcelTM spreadsheet
template which is available on the Schneider public Web site.
Here is the graphic representation of the Global Data Planning Spreadsheet.
