PDU/RPP Registers and Alarms
This section contains information for the PDU/RPP Registers (FC 04) and
PDU/RPP Alarms (FC 02).

PDU/RPP Registers (FC 04)

To read the vendor name in the PDU/RPP, set the Modbus program to
Unit ID 1 and register 1001:
IP: <IP address of PDU/RPP>
Unit ID: 1
Starting Register: 1001
Number of registers: 32
Function Code: 04
The PDU/RPP returns 32 registers containing up to 64 characters. There
are two ASCII characters per register, so the vendor name could be
displayed as POWERWARE.
