DL8000 Preset Instruction Manual
Revised February-2016 Communications Protocols D-65
Some of the transaction data is archived by default
and not configurable. Refer to Section C.2.5,
Transaction History in Appendix C of the
ROCLINK 800 Configuration Software User
Manual (for DL8000) , (Form A6240) for details.
The parameter values are returned in the same
order in which the configuration bits are reported.
All the copies archived for each configured archive
parameter are returned in the response frame.
The number of copies archived for each parameter
is always fixed. For example, 4 for data referring to
components, 4 for data referring to meters, and 6
for data referring to additives.
Example: If configstatus[6](hex) = 0D 90 00 00 00
00, then data following the configstatus[6] in the
response frame is formatted as:
float Unit Address
float Data Item 1
float Data Item 2
float Trans Start Gross Meter 1
float Trans Start Gross Meter 2
float Trans Start Gross Meter 3
float Trans Start Gross Meter 4
float Trans End Gross Meter 1
float Trans End Gross Meter 2
float Trans End Gross Meter 3
float Trans End Gross Meter 4
Note : The DL8000 does not consider the
multiplication factors used for returning
some parameters in other DanLoad 6000
commands when returning the value (read
from the archived data) in the response
frame.
