Clears the input and output buffers of the device.
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Many nodes provide an
error in
input and an
error out
output so that the node can respond to and communicate errors that occur while code is running. The value of
error in
specifies whether an error occurred before the node runs. Most nodes respond to values of
error in
in a standard, predictable way.
error in

If no error occurred before the node runs, the node begins execution normally.
If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as
error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the
error in
value as
error out.

Default:
No error
session out
The resource to which a VISA session is opened.
This output also includes the class for the session, which matches that of
session in.
error out

Commands for 488.2 Instruments (GPIB, VXI, TCP/IP, USB)
-
GPIB—VISA sends the Selected Device Clear command.
-
VXI—VISA sends the Word Serial Clear command.
-
USB—VISA sends the INITIATE_CLEAR and CHECK_CLEAR_STATUS commands on the control pipe.
Commands for Non-488.2 Instruments (Serial Instr, TCP/IP Socket, USB Raw)
-
Serial Instr—VISA flushes (discards) the I/O output buffer, sends a break, and then flushes the I/O input buffer.
-
TCP/IP Socket—VISA flushes the I/O buffers.
-
USB Raw—VISA resets the endpoints referred to by the
USB Settings:Bulk-In Pipe
and
USB Settings:Out Pipe
properties.
Where This Node Can Run:
