Virtual Instrument Operation
RS-232 Virtual Instrument
If the
Yes
option is selected, the VI will initialize all settings from the actual
instrument. If the
No
option is selected, the user should enter all data in the control
fields (
Sensor Length
,
Hi Setpoint
, etc.) in the indicated units. The user should also
select the correct RS-232 port and baud rate, according to the port to which the Model
186 is connected and the baud rate to which the Model 186 is set (see page 30 for
instructions on setting the Model 186 baud rate). The user may then start the VI.
Please refer to your LabVIEW documentation for instructions on how to start and
control the execution of VI’s.
Interacting with the running VI
While the VI is running the user may manipulate the virtual toggle and rotary switches
in the same manner as required for the front panel operation of the actual instrument.
See the Operation section of this manual for instructions on operating the front panel
controls, however, please note that there are some minor differences discussed below.
The RAISE/LOWER toggle switch functions slightly different in the VI. If the
RAISE/LOWER toggle switch is moved from the center position to the RAISE or
LOWER position, then the display changes to show the appropriate parameter. After
approximately 4 seconds in the RAISE or LOWER position, the display will begin
incrementing or decrementing by tenths. After approximately 12 additional seconds,
the display will begin incrementing/decrementing by ones. Move the RAISE/LOWER
toggle switch back to the center position to stop the incrementing or decrementing
function.
The virtual instrument’s FILL LED indicator is only accurate if the fill toggle switch
is in the AUTO position. There is no remote monitoring or control of the manual
override states of the fill toggle switch available through the communication
command set.
