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.
