I've spent less time than I probably should looking at my (mostly small) Lonworks networks through a protocol analyzer. Right now, I have a network with about 55 devices, daisy chained and doubly terminated. LonScanner is reporting about 1% CRC errors and around 60% bandwidth utilization. I've tried filtering the packets by subsystem and get no errors from anywhere when filtered that way. There are no apparent problems with the operation of the system, but the errors worry me. Do I need to worry? Buy a router? Adjust throttles?
