Step 4: Monitoring and Collecting Data

For this step, you are going to monitor live data and save ("collect") data to your computer.

By default, the data logger includes three tables: Public, Status, and DataTableInfo. Each of these tables only contains the most recent measurements and information.

  • The Public table contains the measurements as they are made. It is updated at the scan interval set within the data logger program.
  • The Status table includes information on the health of the data logger and is updated only when viewed.
  • The DataTableInfo table reports statistics related to data tables. It also only updates when viewed.
  • User-defined data tables update at the schedule set within the program.

PC200WBasic data logger support software for direct connect. It supports a connection between computer and data logger and includes Short Cut for creating data logger programs. Tools for setting the data logger clock, sending programs, monitoring sensors, and on-site viewing and collection of data is also included. and PC400Data logger support software that supports a variety of communication options, manual data collection, and data monitoring displays. Short Cut and CRBasic Editor are included for creating data logger programs. PC400 does not support complex communications options, such as phone-to-RF, PakBus® routing, or scheduled data collection. users, click the Monitor Data tab. When this tab is first opened for a data logger, values from the Public table are displayed. To view data from other tables, click the Add button (), select a table or field from the list, then drag it into a cell on the Monitor Data tab.

Collecting Data

After the program has been running for enough time to generate data records, data may be collected and reviewed via your data logger support softwareLoggerNet, RTDAQ, PC400, and PC200W - these Campbell Scientific software applications include at least the following functions: data logger communications, downloading programs, clock setting, and retrieval of measurement data.. Collections may be done manually, or automatically through scheduled collections set in LoggerNet Setup.

Collecting Data Using LoggerNet

  1. Click the Collect Now button ().
  2. After the data is collected, the Data Collection Results window displays the tables collected and where they are stored on the computer.

Collecting Data Using PC200W or PC400

  1. Click the Collect Data tab.
  2. Select an option for What to Collect. Either option creates a new file if one does not already exist.
    • New data from data logger (Append to data files): Collects only the data in the selected tables stored since the last data collection and appends this data to the end of the existing table files on the computer.
    • All data from data logger (Overwrite data files): Collects all of the data in the selected tables and replaces the existing table files on the computer.
  3. Select the tables to collect from the list at the bottom of the window.
  4. Click Start Data Collection.
  5. After the data is collected, the Data Collection Results window displays the tables collected and where they are stored on the computer.
