The data format used for allocating data in the Master is shown below. Data is
allocated as two's complements (8 bytes = 4 words).

Analog Data 2 is used to monitor other analog data in addition to that in Ana-
log Data 1. Select one type of following data other than that allocated for Ana-
log Data 1: Analog input value, peak value, bottom value, top value, valley
value, or rate of change.
Note The comparator function cannot be used with Analog Data 2.
The data format used for allocating data in the Master is shown below. Data is
allocated as two's complements (8 bytes = 4 words).

The Generic Status Flags are used to monitor flags that indicate maintenance
information (Network Power Voltage Monitor Flag, Unit Conduction Time Mon-
itor Flag, and Analog Cumulative Counter Flag). The following data format is
used for allocating flags in the Master (1 byte).
