ILC1 Option Board Information
ILC1 option board information can be displayed on the A3 ALPHA meter LCD.
Tab l e 3 identifies all the items that are available for display. The quantity identifier
must be a numeric character (represented by i in Table 3) and should be unique
for each item that you want to display. Use Metercat meter support software to
select the display items and their associated quantity identifier.
Table 3. Information item and display format
REX LAN ID 1. This item displays the first 4 digits of the ILC1 option board
LAN ID.
REX LAN ID 2. This item displays the last 6 digits of the ILC1 option board
LAN ID.
REX utility ID. This item displays the utility ID for the A3 ALPHA meter/collec-
tor. The utility ID is the same for all meters that are part of the same network.
ILC number of nodes. This item displays the number of REX meters that are
registered to the collector.
ILC number of repeaters. This item displays the number of REX meters that
are registered to the collector and that are operating as a repeater.
Memory Capacity The ILC1 option board will support a maximum of 1024 registered nodes. The
amount of memory required to store current billing data, previous period billing
data, previous season data, and configuration change data limits the amount of
data available for storage of load profile data. There are two variables that con-
trol the amount of shared memory required to store load profile data:
■ The number of REX meters for which load profile data is to be stored.
■ The number of days of data to store for each REX meter.
As these two load profile variables are increased, the maximum number of regis-
tered nodes must be decreased to allow all of the data to fit within the available
shared memory on the ILC1 option board.
Tab l e 4 shows the estimated maximum number of days of load profiling data
that can be stored for various configurations. Table 4 assumes the A3 ALPHA
meter/collector does the following:
■ reads load profiling data from each registered REX meter based on the
following schedule:
■ for 15-minute intervals, the collection time is every 4 hours
■ for 30-minute intervals, the collection time is every 6 hours
■ for 60-minute intervals, the collection time is every 12 hours
■ reads and stores load profiling data for all registered nodes
The ILC1 option board memory configuration is set at the factory and cannot be
changed.
