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 f or

Breaker #1 in Panel #6 of the PDU/RPP at the specified IP address.
