PDU/RPP Alarms (FC 02)

The PDU/RPP monitors the condition of several parameters and can

activate an alarm status if a parameter is out of range. For example, if

the input frequency is too high or too low, the PDU/RPP can set the

Input Frequency Fault Alarm.

To read the Input Frequency Fault Alarm, set the Modbus program to

Unit ID 1 and coil address 1008:

IP: <IP address of PDU>

Unit ID: 1

Starting Register: 1008

Number of Registers: 1

Function Code: 02

The PDU/RPP returns a single register that is a BOOL value (0 or 1),

indicating if the alarm is active or not active.
