124 Interoperable Interface for the Street Light Bridge
Interface
You can use the Segment Controller to view the interoperable interface for a
Street Light Bridge module from the module’s Properties Web page.
The interface includes output data points (network variables) that contain status
information for the Street Light Bridge module. The interface also includes input
data points (network variables and configuration network variables) that define
the operational characteristics of the Street Light Bridge module.
In general, you should not need to modify any of the data points, and there are a
number of them that you should not modify unless directed to do so by Echelon
Support. You might need to read and report data from these data points when
troubleshooting a problem with assistance from Echelon Support.
Output Variables
Table 2 lists the output data points that are defined for the Street Light Bridge’s
interoperable interface.
Table 2. Output Data Points
Variable Description
nvoSlbStatus Provides internal status and statistics information.
nvoProtocol Indicates the current RF Tunneling Protocol (RTP) version. Zero
indicates the initial version.
nvoVersion Provides the version numbers for both the bootrom and the application.
nvoSlbError Reports the most recent internal error area and code. This value does
not persist across device reset.
A value of 0 indicates no error. However, not all non-zero codes
represent errors.
nvoSlbInfo Provides the model number for the mainboard, the revision number for
the RF board, and the device RF address.
Input Variables
Table 3 on page 125 lists the input data points that are defined for the Street
Light Bridge’s interoperable interface. You should not modify data points that
have “No” in the table’s
Modifiable column unless you are directed to do so by
Echelon Support. Modifying these data points can degrade a Street Light Bridge
module’s performance or interrupt communications.
