Set the date and time you would like to receive the next report. This only needs to be set once
for the first report. After that, it will automatically send at the programmed intervals. This is
useful if you would like your reports sent at the top of the hour or at a specific time of day. The
report interval can be set between 0 hours 0 minutes and 199 hours 59 minutes.
DATALOGGING
SCADA 3000’s built-in Data Logger can log and store up to 50,000 samples from up to 128
Data Points. All samples are logged at the same time on a programmable time interval. Each
stored sample includes a time and date stamp with the year stored as four digits. The Data Log
viewer allows you to select or query stored data from multiple units and display it in grid for-
mat. From the grid you may copy the data to the Windows Clipboard and paste it into another
application such as MS Excel or Lotus 123 or you can export the data in a comma-delimited
format. The Data Log Viewer also provides the ability to graph one or more data points on a
line chart.
From the main programming form choose Programming>DataLog or simply click on the
DataLog button from the toolbar. The Data Log programming screen is shown below:

Programming the SCADA 3000 Data Logger requires four steps:
(1) Select the items you wish to log & click on the commit button.
(2) Set the time interval for logging.
(3) Set the time you wish to start the Datalogger.
(4) Click the Enable box.
The following information describes in detail how to complete these steps and also how to
retrieve and view the Data Log information.
Data Logging Capacity
The SCADA 3000 has enough memory to store up to 100,000 pieces of information, including
the time stamp. This means that if you are datalogging one point, the memory would store one
time-stamp and one value at each interval, resulting in 50,000 time stamps and 50,000 values—
100,000 records. A record thus comprises one time-stamped log of the selected data points. If
you select more than one point to be logged, the SCADA 3000 will store a time stamp plus the
value for each point selected. The following formula can be used to determine the number of
time-stamped records for a given number of points:
Time-stamped Records =
100,000
# of points +1
