4.32 RS232 Interface Commands
SYSTem:LOCal
This command makes the power supply switch to local mode from remote mode. All keys on the front panel are fully
functional. The “REM” annunciator on the display is off.
SYSTem:REMote
This command places the power supply in the remote mode. All keys on the front panel, except the “Local” key, are disabled.
The “REM” annunciator on the display is on.
SYSTem:RWLock
This command places the power supply in the remote mode. All keys on the front panel, including the “Local” key, are
disabled. The “REM” annunciator on the display is on.
Ctrl-C
This command clears the operation in progress over remote interface and discards any pending output data.
4.33 The SCPI Status Registers
All SCPI instruments implement status registers in the same way. The status system records various instrument conditions in
three register groups: the Status Byte register, the Standard Event register, and the Questionable Status register group. The
Status Byte register records high-level summary information reported in the other register groups. Chapter Five will illustrate
how to use SCPI status registers.
4.34 What is an Event Register?
An event register is a read-only register that reports defined conditions within the power supply. Bits in an event register are
latched. Once an event bit is set, subsequent state changes are ignored. Bits in an event register are automatically cleared
by a query command of that register (such as *ESR? Or STAT:QUES:EVEN?) or by sending the *CLS command. A reset
(*RST) or device clearance command will not clear bits in event registers. Querying an event register returns a decimal value
which corresponds to the binary-weighted sum of all bits set in the register.
4.35 What is an Enable Register?
An enable register defines which bits in the corresponding event register are logically grouped together to form a single
summary bit. Enable registers are both readable and writable. Querying an enable register will not clear it. The *CLS (clear
status) command does not clear enable registers but it does clear the bits in the event registers. To enable bits in an enable
register, you must write a decimal value which corresponds to the binary-weighted sum of the bits you wish to enable in the
register.
