SYSTem:COMMunicate:RLSTate LOCal|REMote|RWLock
SYSTem :COMMunicate:RLSTate?
Configures the remote/local state of the instrument.
Remote and Local do the same thing and are included for compatibility with other products. Both allow
front panel control.
RWLock disables the front panel keys. Then the instrument can only be controlled remotely.
Parameter Typical Return
LOCal|REMote|RWLock, default LOCal LOC, REM, or RWL
Sets the remote/local state to remote: SYST:COMM:RLST REM
l The remote/local state is unaffected by *RST or any SCPI commands other than SYSTem:COMMu-
nicate:RLState.
l The remote/local instrument state can also be set by other interface commands over the GPIB
and some other I/O interface.
l When multiple remote programming interfaces are active, the interface with the most recently
changed remote/local state determines the instrument’s remote/local state.
SYSTem:COMMunicate:TCPip:CONTrol?
Returns the initial socket control connection port number. After the control port number is obtained, a
control socket connection can be opened.
Parameter Typical Return
(none) 5000 (0 if sockets are not supported)
Query the Control connection port number: SYST:COMM:TCP:CONT?
l The control socket connection can only be used by a client to send a Device Clear to the instru-
ment or to detect Service Request (SRQ) events.
l Refer to Using Sockets for more information.
SYSTem:ERRor?
Reads and clears one error from the error queue.
Parameter Typical Return
(none) <+0,"No error">
Reads and clears the first error in error queue: SYST:ERR?
l The front-panel ERR annunciator turns on when one or more errors are currently stored in the
error queue. Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them.
