Interoperable Interface for the Street Light Bridge
Interface
You can use the Segment Controller to view the interoperable interface for a CRD
3000 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 CRD 3000 Street Light Bridge module. The interface also
includes input data points (network variables and configuration network
variables) that define the operational characteristics of the CRD 3000 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 Data Points
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 Data Points
Table 3 on page 105 lists the input data points that are defined for the Street
Light Bridge’s interoperable interface. You should not modify those data points
that have “No” in the table’s Ok to Modify column unless you are directed to do so
by Echelon Support. Modifying these data points can degrade a CRD 3000 Street
Light Bridge module’s performance or interrupt communications. You could
potentially include any data points that have “Yes” in the table’s Ok to Modify
column in an application program or FPM used in your installation.
