0.4 Unreported Record Status ( 3 0 4 )
This command will respond with the number of unacknowledged operation and fault records.
To mark the record as being reported, a 3 6 12 command will retrieve the oldest unreported differential fault record and
decrement the unreported differential fault record counter by one.
Likewise, a 3 6 13 command will retrieve the oldest unreported through fault record and decrement the unreported through
fault record counter by one.
The 3 6 14 command will retrieve the oldest unreported harmonic restraint record and decrement the unreported harmonic
restraint record counter by one.
The 3 6 15 command will retrieve the oldest unreported operations record and decrement the unreported operations record
counter by one.

0.5 Reset Alarms/Target LEDs ( 3 0 5 )
The targets, alarms and relay status flag (see command 3 4 1 msg 2/1) will be reset on the TPU. After the relay receives this
command it will transmit an ACK/NACK based on the TPU completing the command.
0.6 Reset Max/Min Demand Currents ( 3 0 6 )
This command will reset the maximum and minimum demand current values along with their time tags. After the relay
receives this command it will transmit an ACK/NACK based on the TPU completing the command.
0.7 Show Logical Input/Output Status ( 3 0 7 )
This command displays the binary value of the logical input and output table for the present state of the unit.
