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 5.1.2 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.
