Stored Operating States

Your power supply has registers that can store up to 10 operating states. These states can be recalled in arbitrary order. Storing a state involves taking a "snapshot" of the voltage and current settings that are in effect when the command is received. The following example uses stored operating states to set up an output. Using this method of setting up outputs saves processing time and facilitates repeating the same commands.

10 ASSIGN @Ps TO 705

20 OUTPUT @Ps;"OUT1,0;OUT2,0"

30 !

40 OUTPUT @Ps;"VSET1,1;ISET1,.1;VSET2,5;ISET2,.1;5TOl"

50 OUTPUT @Ps;"VSET1,2;ISET1,.2;VSET2,4;ISET2,.2;STO2"

60 OUTPUT @Ps;’’VSET1,3;ISET1,.3;VSET2,3;ISET2,.3;STO3"

70 OUTPUT @Ps;"VSET1,4;ISET1,.4;VSET2,2;ISET2,.4;STO4’’

80 OUTPUT @Ps;"VSET1,5;1SET1,.5;VSET2,1;1SET2,.5;STO5"

90 !

100 OUTPUT @Ps;"CLR"

110 FOR State= 1 TO 5

120 OUTPUT @Ps;"RCL";State

130 WAIT 2

140 NEXT State

l50 END

LINE 10: Assigns the I/O pathname to the power supply.

LINE 20: Disables output 1 and output 2.

LINE 40-80: Stores 5 operating states for output 1 and output 2 in storage registers 1 through 5. Outputs not explicitly programmed will store the settings that are in effect when the store command is received.

LINE 100: Clears the supply. All outputs are enabled and set to the initial power on state (0 volts; minimum current setting).

LINE 110-140: Loops through the sequence of five states with a two second wait between states.

Programming Outputs Connected In Parallel

Only outputs that have equivalent voltage and current ratings can be connected in parallel.

When programming outputs that are connected in parallel, it is convenient if you first know if you will be operating in CC or CV mode. Refer to Chapter 4 for more information on parallel operation.
