Alarm Table Organization
The Alarm Table begins at %R9030 and ends at %R9190. The Alarm Table organization is
shown below.
Variable Name
NUM_FLT
NUM_FLT [001]
NUM_FLT [002]
NUM_FLT [003]
NUM_FLT [004]
NUM_FLT [005]
NUM_FLT [006]
NUM_FLT [007]
NUM_FLT [156]
The value in NUM_FLT (%R09030) indicates the number of active faults (alarms) in the table.
A value of zero indicates that the fault table is empty. A value of 33 indicates that the table
is full. When the table is full, no further faults may be added to the table.
The first fault table entry is in NUM_FLT [001.005] (%R9031.9035). The second fault entry is
in NUM_FLT [006.010] (%R9036.9040). This pattern is repeated for a total of 32 fault
records.
Alarm Record Structure
Each record in the Alarm Table consists of 5 registers. Each register may be interpreted as a
pair of bytes whose definitions are shown in the table below. If the registers are displayed as
hexadecimal values in Logic Developer PLC, then the interpretation may be simplified.
