e) FUNCTION CODE 06H: STORE SINGLE SETPOINT
This function code allows the master to modify the contents of a single setpoint register in a 750/760. Setpoint registers are
always 16 bit (two byte) values transmitted high order byte first (see the Memory Map on page 7–13 for details). The follow-
ing table shows the format of the master and slave packets. It shows a master device storing the value 200 at memory map
address 1100h to slave device 11.

OPERATION
CODE (HEX)
DEFINITION DESCRIPTION
0000 NO OPERATION Does not do anything.
0001 RESET Performs the same function as the front panel key.
0002 OPEN BREAKER Performs the same function as the front panel key. The 760 must be in
Remote Mode for this operation to be effective.
0003 CLOSE BREAKER Performs the same function as the front panel key. The 760 must be in
Remote Mode for this operation to be effective.
0004 SET TIME Sets the internal clock time. See page 7–8 for details.
0005 SET DATE Sets the internal clock date. See page 7–8 for details.
0006 TRIGGER TRACE MEMORY Performs the same function as the logic input function
TRIGGER TRACE MEMORY.
0007 CLEAR ENERGY USE DATA Performs the same function as
CLEAR ENERGY USE DATA command.
0008 CLEAR MAX DEMAND DATA Performs the same function as the
CLEAR MAX DMD DATA command.
0009 CLEAR EVENT RECORDER
DATA
Performs the same function as the
CLEAR EVENT RECORDER DATA command.
000A RESET TRIP COUNTER DATA Performs the same function as the
RESET TRIP COUNTER DATA command.
000B RESET ARCING CURRENT
DATA
Performs the same function as the
RESET ARCING CURRENT DATA command.
000C DISPLAY OVERRIDE PACKET Displays the 40 character (20 register) Override_Packet (addresses 10B1 to 10C4
hex) for the time specified in Override_Time (address 10B0 hex).
000D TRIGGER DATA LOGGER Performs the same function as the logic input function
TRIGGER DATA LOGGER.
000E RESET TRACE MEMORY Resets the Trace Memory oscillography data by clearing the number of captured
events to zero.
000F RESET DATA LOGGER Resets the Data Logger by clearing the number of captured events to zero.
0010 RESET AR COUNT DATA Resets the Autoreclose Count by setting the
AR SHOT COUNT to zero.
0011 RESET AR RATE DATA Resets the Autoreclose Shot Rate by setting
AR SHOT RATE to zero.
