Via VXI-11 protocol: &LLO interface message

Many instrument driver commands, e.g. the NI commands SetRWLS (Set Remote
With Lockout State) or SendLLO, also contain a local lockout command.
In the local lockout state an unintentional return to manual control is not possible. All "Go
To Local" options listed above are blocked (hotkey and remote control). The "Go To
Local" hotkey is replaced by a disabled "Local Lockout" hotkey.
The local lockout can be disabled as follows:
●
Via GPIB bus or HiSLIP protocol: deactivate the REN control line
●
Via VXI-11 protocol: &NREN interface message
5.1.4 Monitoring the Remote Control Interface
You have several possibilities to monitor the control interface:
●
Use the SCPI remote trace functionality integrated in the LXI homepage of the instru-
ment, see chapter 5.9.2, "LXI Browser Interface", on page 187.
●
Create a report file. To enable or disable the creation of report files use the "Report
File" hotkey displayed while remote control is active.
SCPI Command:
TRACe:REMote:MODE:FILE<inst>:...
See chapter 6.3.6, "Tracing the Remote Control Interface", on page 208
●
Access the SCPI remote trace directly via the "Remote" dialog, displayed while
remote control is active. To configure the display use the "Report Display" hotkey.
The hotkey toggles between the following modes:
– OFF: tracing is disabled
– LIVE: messages are traced and displayed
– ANALYSE: stop tracing to analyse already traced messages
The displayed remote trace is similar to the remote trace displayed via the LXI home-
page, with the softkeys provided in ANALYSE mode corresponding to toolbar buttons
of the LXI remote trace.
For a detailed description of the LXI remote trace see chapter 5.9.4, "SCPI Remote
Trace", on page 191.
