fclose
Disconnect interface object from instrument
Syntax
fclose(obj)
Arguments
| An interface object or an array of interface objects. |
Description
fclose(obj) disconnects
obj from the instrument.
Examples
This example creates the GPIB object g, connects
g to the instrument, writes and reads text data, and then
disconnects g from the instrument using
fclose.
g = gpib('ni',0,1);
fopen(g)
fprintf(g,'*IDN?')
idn = fscanf(g);
fclose(g)
At this point, you can once again connect an interface object to the instrument.
If you no longer need g, you should remove it from memory with
the delete function, and remove it
from the workspace with the clear command.
Tips
If obj was successfully disconnected, then the
Status property is configured to closed
and the RecordStatus property is configured to
off. You can reconnect obj to the
instrument using the fopen function.
An error is returned if you issue fclose while data is being
written asynchronously. In this case, you should abort the write operation with the
stopasync function, or wait for
the write operation to complete.
