Breaker #1 Data Registers (FC 04)

To specify a specific breaker, use a Unit ID for breaker data along with
the register number for the specific breaker.
For example, “Watts in Phase A” is register 1055 for Breaker #1. This
statement is true for any panel. To specify a specific panel for breaker
data, use the panel’s Unit ID in the Modbus program. For Panel #6
(Unit ID 23), the Modbus program would be set as follows:
IP: <IP address of PDU/RPP>
Unit ID: 23
Starting Register: 1055
Number of registers: 2
Function code: 04
The Modbus program would return a value of the watts in Phase A for
Breaker #1 in Panel #6 of the PDU/RPP at the specified IP address.
