Section 10. Utilities Installed with LoggerNet

10.3.3.5 Data Tab

The fifth tab can be used to view the values associated with the most recently

collected record from any table.

To begin, select the table you wish to monitor from the drop-down list. Press

the

Poll Table button to poll the specified table or the Poll All button to poll all

tables. The fields of the specified table will be displayed in the grid.

10.3.4 Deleting a Station

An RWIS station can be deleted from LoggerNet’s network map by selecting

that station and either pressing the

Delete Station button or selecting Edit |

Delete Station from the menu. The application will present a message box

asking you to confirm the delete operation. If confirmed, the selected station

will be deleted.

10.3.5 Organization of RWIS Data in LoggerNet

The LoggerNet server groups related NTCIP-ESS variables into tables and

each of these tables has an associated collect area. The grouping of variables

as well as the order in which they are declared is derived from the variables

that are defined as blocks in NTCIP-ESS version 2. The tables that are present

as well as the variables that are assigned to them are defined in an XML file

that, at present, is statically linked as a part of the LoggerNet server DLL.

Future versions may have the ability to dynamically specify tables and variable

assignments within those tables. The following sections describe the layout of

each of these tables. Details about the interpretation of these variables can be

found in National Transportation Communications for ITS Protocol

Environmental Sensor Station Interface Standard – Version 02

[http://ntcip.org/library/documents/pdf/1204v02-23b.pdf].

Some of the variables defined by NTCIP-ESS specify the number of instances

of other variables. For example, numEssTemperatureSensors is defined to

specify the number of instances of other variables that follow. Also some

variables are supported only for a specified version of NTCIP-ESS. The

LoggerNet server uses this information when it forms table definitions

associated with collect areas. It will filter out variables that do not match the
