5.6.3 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.)
