4.4 Return to Manual Operation – LOCAL Menu
LOCAL The LOCAL menu is displayed on switching the instrument to remote control mode.
At the same time, the hotkey bar is blanked out and all keys are disabled except the
PRESET key.
The LOCAL softkey and the DISPLAY UPDATE ON/OFF softkey are displayed.
Depending on the setting of the DISPLAY UPDATE ON/OFF softkey, the diagrams,
traces and diplay fields are displayed or hidden. For further details on the DISPLAY
UPDATE ON/OFF softkey refer to Instrument Setup and Interface Configuration –
SETUP Key .
The LOCAL key switches the instrument from remote to manual operation, with the
assumption that the remote controller has not previously set the LOCAL LOCKOUT
function.
A change in the control mode consists of:
• Enabling the Front Panel Keys
Returning to manual operation enables all inactive keys and turns on the hotkey
bar. The softkey menu which is displayed is the main menu of the current mode.
• Inserting the measurement diagrams
The blanked diagrams, traces and display fields are inserted.
• Generating the message OPERATION COMPLETE
If, at the time of pressing the LOCAL softkey, the synchronization mechanism via
*OPC, *OPC? or *WAI is active, the currently running measurement procedure is
aborted and synchronization is achieved by setting the corresponding bits in the
registers of the status reporting system.
• Setting Bit 6 (User Request) of the Event Status Register
With a corresponding configuration of the status reporting system, this bit
immediately causes the generation of a service request (SRQ) which is used to
inform the control software that the user wishes to return to front-panel control.
This information can be used, e.g., to interrupt the control program so that the user
can make necessary manual corrections to instrument settings. This bit is set
each time the
LOCAL softkey is pressed.
If the LOCAL LOCKOUT function is active in the remote control mode, the front-
panel
PRESET key is also disabled. The LOCAL LOCKOUT state is left as soon
as the process controller de-activates the REN line or the GPIB cable is discon-
nected from the instrument.
