Panel Summary Registers (FC 04)

NOTE The panel can be wired for either a wye (phase to neutral) or a delta
(phase-to-phase) configuration. The registers contain only the data supported by the wired
configuration. For example, if the panel is wired in a wye configuration, the voltages AN, BN,
and CN are available, but the voltages AB, BC, and CA are not available (an exception code is
returned). Refer to the actual panel for the wiring configuration.
Table 5 shows the registers that contain summary data for the panel.
The registers contain the total information for all the breakers in the
panel.
For example, the AC Voltage between Phase A and Neutral is available
in register 4010. To read the AC Voltage in Phase A at Panel #1, set the
Modbus program to Unit ID 2 and register 4010:
IP: <IP address of PDU/RPP/RPM>
Unit ID: 2
Starting Register: 4010
Number of Registers: 2
Function Code: 04
To read the AC Voltage in Phase A at Panel #4, set the Modbus program
to Unit ID 5 and register 4010:
IP: <IP address of PDU/RPP/RPM>
Unit ID: 5
Starting Register: 4010
Number of Registers: 2
Function Code: 04
