*Field 5 - Never observed a packet with this length and subtype that wasn't all FF's
*Field 5 - Never observed a packet with this length and subtype that wasn't all FF's


*Field 6 - Have only seen this change when comparing data from different energy providers
*Field 6 - WAN Address - Oncor uses GPS coordinates, CoServ uses LAN with padding of some kind


*Field 7 - Appears to either be location identifier (Oncor) or duplicate meter ID (Coserv)
*Field 7 - Increments some amount with each transmission and rolls over at 0xFF, always an even hex value


*Field 9 - Increments some amount with each transmission and rolls over at 0xFF
*Field 8 - Value in seconds since meter powered on, '''easy way to see last time the meter experienced a power outage.'''
 
*Field 10 - LAN Address, Meter ID that's listed on the sticker on the front
*Field 10 - Value in seconds since meter powered on, '''easy way to see last time the meter experienced a power outage.'''
