Setting Up Scheduled Data Collection

The data to be collected and the output file locations and format are specified on the datalogger Data Files tab. The Schedule tab is used to define the interval on which the LoggerNet server will check the datalogger for new data. If new data exists, it will be stored in the data files and the LoggerNet data cache.

To set up a data collection schedule for a datalogger, first ensure that your device map has been configured with all of the devices listed as they actually exist. Next, determine which tables should be collected from the datalogger each time a data collection attempt is made. If no tables are selected on the Data Files tab, no data will be collected from the datalogger.

You should check the directory path and the data file options to make sure the files are where you want them and in the right format. Note that each table must be configured separately (that is, selected for collection, file name provided, file format specified, etc.).

NOTE: If no table names appear on the Data Files tab, click the Get Table Definitions button.

The data collection schedule should be set up next. Set the base date and time to when you would like the first data collection attempt to occur and set the interval at which subsequent data collection attempts should occur. Make sure that communications are enabled for all devices in the communications path, and that scheduled collection is enabled. If the initial date and time is set to a time that has already passed, data collection will begin immediately.

The Status Monitor screen can be used to ensure that data collection is occurring on the defined schedule. Some issues will also be identified by the TroubleShooter. If data is not being collected, check the following:

• The Scheduled Collection Enabled box on the Schedule tab for the datalogger must be selected. This turns the schedule “on”. You can temporarily disable data collection by clearing this check box and applying the change.

• The tables from which you desire data should be enabled for collection in the Data Files tab of the Setup Screen.

• All devices in the communications path to the datalogger must have the Communications Enabled check box on the Hardware tab selected.

• Unsuccessful attempts to communicate with the datalogger may exhaust the number of Primary Retries specified so that the Secondary Retry interval is in effect. Check the date and time listed for the next data collection in the Status Monitor.

• Look at the collection state data for the datalogger in the Status Monitor. This is displayed as one of four states.

  • Normal collection

  • Primary retry

  • Secondary retry

  • Collection disabled

• Check the Status Monitor window and ensure the Pause Schedule check box is cleared.

• Ensure the table definitions have been retrieved from the datalogger and are current.
