Appendix C. Troubleshooting Tips 
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.

LonWorks but is the wrong firmware for the application.  Remove LonWorks from the configuration or get  new 
firmware/hardware.
