Templates LogConfig.xls and TrendConfig.xls provided with Bulk Data
Management in Engineering Workplace.

Property Logs
The Bulk Configuration tool helps you configure and instantiate property logs for a
large quantity of object properties without having to add the logs on an object-by-
object, and property-by property basis in the Plant Explorer. This tool is an add-in
for Microsoft Excel.
The Bulk Configuration tool lets you generate a load report which calculates the
disk space occupied by existing file-based property logs, and additional disk space
which will be required as a result of instantiating new property logs via this tool.
This report helps you to determine whether you need to adjust the disk space
allocation for file-based logs. This tool also lets you verify whether or not the logs
have been created when you are done.
Import filters in the Bulk Configuration tool can be used to shorten the time it takes
to read information from aspect objects into the Excel spreadsheet. The most
effective filter in this regard is an import filter for some combination of object types
and properties. Since some objects may have hundreds of properties, the time
savings can be significant.
