PDU/RPP Unit ID Numbers
Because the PDU/RPP consists of several panels of circuit breakers, set
the Unit ID in the Modbus program to specify a specific PDU/RPP, a
specific panel, or a specific breaker (see Table 2).
The PDU/RPP has a Unit ID of 0, 1, or 255. The same PDU/RPP
information can be obtained from any of these IDs. See “PDU/RPP
Registers and Alarms” on page 54 for more information.
The panel Unit IDs range from 2 to 17. These summary data panel
registers contain the total information for all the breakers in a specific
panel. For example, the registers show the sum total current for each
phase distributed by all the breakers. See “Panel Registers and Alarms”
on page 60 for more information.
The breaker Unit IDs range from 18 to 33. These registers provide
individual breaker data for the specified panel. See “Breaker Data and
Alarms” on page 64 for more information on identifying specific breaker
registers.
If there is an optional Environmental Monitoring Probe (EMP) installed,
use Unit ID 254 to obtain EMP data. See “Environmental Monitoring
Probe (FC 03 or 04)” on page 68 for more information.
