Data Source Browser

Highlight the value to be used for the component and then click OK.

In LoggerNet, the directory tree includes all dataloggers in the network maps for all LoggerNet servers in the project, as well as all data files, LNDB databases, HTTP dataloggers, and virtual data sources that have been added as data sources. It can be expanded to see the tables for each datalogger and the data values for each table or data file by clicking on the + marks to the left of the datalogger, table, or data file. Note that in RTDAQ, RTMC projects are limited to a single station. This station must be specified when a new project is opened. Thus when components are added to a project, only the specified station's tables and fields will be shown in the data source browser.

In LoggerNet, a green check mark beside a table name indicates that the table is being collected on a schedule. A red X indicates that the table is not set up for scheduled collection in LoggerNet. Note that data cannot be displayed by RTMC unless it is being collected. Scheduled collection can be enabled and tables can be included for data collection in LoggerNet's Setup window. In RTMC Pro, you can also set up data collection from the Project | Configure Override Scheduled Collection menu item. This data collection will be in addition to any scheduled collection setup in LoggerNet's Setup window. Using this option will not generate green check marks next to the table in the data source browser. (Green check marks indicate only that the table is set up for scheduled collection in LoggerNet.) However, RTMC will still be able to display the data.

In RTDAQ, when associating a data value from a table with a component, the station's table will be represented with a green check mark when RTDAQ is connected to the station and monitoring the table through a real-time window (field monitor, table monitor, graph, etc.). A table will be represented with a red X when RTDAQ is not monitoring the table. When RTDAQ is connected to the station, RTMC will perform a manual poll to update the project data every second. Thus, RTMC data displays will only be updated when RTDAQ is connected to the station. In RTMC Pro, you can override this one second collection from the Project | Configure Override Scheduled Collection menu item.

An R beside a data value indicates that the data value is Read-Only. An RW beside a data value indicates that the data value is Read/Write. Only Read/Write values can be edited.

If the data values in a data source have changed since RTMC was opened, the Refresh button () at the bottom right of the dialog box can be used to update the data values in the Data Source Browser.

The data value can also be typed in directly, in the form of "Source:datalogger.table.variable" (such as "MySource:CR1000.hourly.temp", where MySource is the name of the server data source or file data source, CR1000 is the name of the datalogger in the network map, hourly is the table name, and temp is the data value).

The data value to be displayed can be processed using an expression. For instance, a temperature reading in degrees Celsius can be processed to display in degrees Fahrenheit using a mathematical expression. For a list of functions and operators that are supported, see Expressions.
