Configuration checksum value and date
The Mark III meter maintains a configuration checksum value 
(
CnfgChksumValue) and associated date (CnfgChksumDate). These values can be used to 
determine if and when the meter configuration has last changed. In general, the data points 
included in the configuration checksum consist of the write-protected configuration points and 
the communication-related configuration points.
To determine whether a particular data point is included in the configuration checksum, consult 
Daniel MeterLink online help. (There is a help topic for each data point, and each topic indicates 
whether the data point is one that is included in the configuration. From Daniel MeterLink, click 
on Help, click on Mark III
 Registers Reference
, select the 
Index
 tab, start typing the data point 
name until the desired point is highlighted, and then click the 
Display
 button.)
