Each History Log allows long term monitoring of up to sixteen data points at sample rates from 5 minutes to 24 hours. Data is collected continuously by the server and stored indefinitely. Report tools include a tabular report for a user defined date/time range as well as a charting tool to plot the data in graphical format. The amount of data that may be stored and retained is limited only by computer disk storage space.
A virtually unlimited number of independent history logs may be defined on the system and some or all of the defined logs may be active and collecting data at any given time. For each log, the operator selects the number of samples to be collected and the sampling period desired.
The data is available indefinitely for reporting in both graphical and tabular formats. History data can also be easily exported for use in other programs such as spreadsheets or trend analysis tools.
