4.16 Selecting Remote and Local Control Modes
After switching mains power on, the manual operating mode is
always active (local state). All front panel controls are enabled and
the device can be operated manually.
LOCAL —> REMOTE
– Switching from manual to remote control
Switching to remote control occurs:
At the IEC bus when the REN line is activated by the controller
and the device is addressed as a listener.
At the serial interface as soon as data are transmitted to the
device.
a)
REMOTE
LOCAL
– Switching from remote to manual control
The device is returned to manual operation:
Manually:
– By activating the <CE/LOCAL> key, as long as it has not
been disabled by the controller during IEC bus operation
(
c)
Via the IEC bus:
– By transmitting the addressed GTL (GO TO LOCAL) interface
command to the device (selective switching to manual
operation)
Programming example (HP Basic):
LOCAL 712
or
– If the REN line is deactivated by the controller (switches all
devices to manual operation)
Programming example (HP Basic):
LOCAL 7
LOCAL LOCKOUT
– Disabling manual switching to manual operation
(only relevant for control via the IEC bus)
The IEC bus controller can disable the LOCAL key at the
device with the LLO (LOCAL LOCKOUT) universal interface
command, preventing manual switching to the manual
operating mode (remote state with lock).
Programming example (HP Basic):
LOCAL LOCKOUT 7
Comments
The “REMOTE” LED indicates the momentary control mode:
LED on = remote control
LED off = manual control
Switching back and forth between the two control modes does
not cause any changes to current device settings or stored
parameters.
Exception: If the display has been switched off it is reactivated
when switching from REMOTE to LOCAL (DISPLAY OFF —>
DISPLAY ON).
IEC bus control: The device is capable of receiving programming
data in the manual operating mode, but they are not executed.
