IEEE 488.2 and SCPI Command Operation Sorensen SF Series

Command Description SCPI Q?

SYST:LOCAL

SYST:LOCAL <ON|OFF> is a special purpose

programming command that may be used to

cause source to be set to the local state or to

the remote state. This command has two

noteworthy circumstances under which it may

prove necessary. The first case involves using

RS232 to communicate with the supply, since

the normal GPIB mechanisms for transition

between local and remote and back again do

not exist when using RS232. The other case is

when the REMOTE/LOCAL switch S1-1 is

placed in the ON position—thereby disabling

the GPIB mechanism for transition from remote

to local. The SYST:LOCAL ON command

provides a means for the system computer to

force the source to the local state. Also, the

SYST:LOCAL? query command is available to

examine the local-remote state of the supply.

And the command SYST:LOCAL OFF may be

used to force supply to the remote state.

N Q

SYST:LOCAL:LOCKOUT

The SYST:LOCAL:LOCKOUT <0|1|OFF|ON>

command provides a means of controlling the

local lockout functionality that is an alternative

to the low level GPIB LLO command.

In contrast, using the GPIB LLO low level

command causes the supply to be placed into

the local lockout state. To place the supply into

the local lockout state, use the

SYST:LOCAL:LOCKOUT command.
