SYSTem Subsystem
SYSTem:COMMunicate:RLSTate LOCal |REMote | RWLock
SYSTem:COMMunicate:RLSTate?
Places the instrument in remote or local mode. The LOCal parameter is the same as SYSTem:LOCal, the
REMote parameter is the same as SYSTem:REMote, and the RWLock parameter is the same as
SYSTemRWLock. The query returns LOC, REM, or RWL.
SYSTem:ERRor[:NEXT]?
Queries the power supply's error queue. When the front-panel ERR annunciator turns on, one or more
errors have been detected. Up to 20 errors can be stored in the error queue. See Error Messages.
— Errors are retrieved in first-in-first-out (FIFO) order. The ERR annunciator turns off after the last error
is read.
— If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is
replaced with -350, “Queue overflow”. No additional errors are stored until you remove errors from
the queue. If no errors have occurred when you read the error queue, the power supply responds with
+0, “No error”.
— The error queue is cleared when power has been off or after a *CLS (clear status) command has been
executed. The *RST (reset) command does not clear the error queue.
SYSTem:LOCal
Places the power supply in the local mode. All keys on the front panel are fully functional.
SYSTem:REMote
Places the power supply into remote mode for remote operation. When the unit is being controlled
remotely, the power supply will go to remote mode automatically. You can switch the instrument to
local mode using SYSTem:LOCal or by pressing any key on the front panel.
