Appendix C. Troubleshooting
Appendix C.1. Debugging a LonWorks connection: Hints and tips
To test connections, set the configuration tool into a mode that will display service requests, and then push
the button on the FieldServer. A request should appear.
In order for variables to appear as outputs, they need to be declared as write variables in the FieldServer.
Declaring the Map Descriptor functions as WRBC, or WRBX can do this. See Section 6.1.2 for more
information.
If the domain and Subnet ID are defined in the configuration file of the FieldServer, these values will be used
when power is cycled to the FieldServer. If the values set here are different to what the Network Manager has
set up for the FieldServer for clients using implicit addressing, the FieldServer will stop communicating. In this
case, change these settings or remove them from the configuration file completely and recommission the
FieldServer.
Appendix C.2. Error Messages
Message Description
"LON:#03 FYI. Standard driver build. This is normal. This message is informational and can be safely ignored.
Appendix C.2.1. Error Message Lonlive.c 121
If the following error message is returned:
DRIVER-> LON : Error, timeout while waiting for Lon I/F to reset!-------- Configuration Error ------
It is possible that the FieldServer hardware in use may not support LonWorks, or the firmware loaded contains
LonWorks but is the wrong firmware for the application. Remove LonWorks from the configuration or get new
firmware/hardware.
Appendix C.3. Communication Errors using Neuron_ID Polling
In order to allow communication across routers when using Neuron_ID based polling, routers need to be set up to
forward NID addressed messages to/from the connected channels.
Appendix C.4. Monitoring Node Status
When monitoring Node Status with a configuration using implicit addressing, it is important that at least one of the
Map Descriptors has active functions (Wrbc, Rdbc). This will cause traffic and when the traffic stops, this will
indicate that the Node is offline.
