■
If a record type contains non-zero data or has no data (i.e., the data
is missing), “... records” are created. In either case, a data record for
every 15-minute interval is created. The data could be missing for a
number of reasons (see Fig u reE-1, “Circuit Element Detail Menu
(no data available),” on page E-12):
• Connection to the node could not be made.
• Connection to the node was made, but access to the circuit
element could not be made.
• The registers in the circuit element were reset, either manually
or by powering down the CSU within in the last 12 hours.
