instrreset

(To be removed) Disconnect and delete all instrument objects

This function that uses serial, Bluetooth, tcpip, udp, visa, or gpib will be removed in a future release. Use serialport, bluetooth, tcpclient, tcpserver, udpport, or visadev instead. For more information on updating your code, see Compatibility Considerations.

Syntax

instrreset


Description

instrreset disconnects and deletes all instrument objects.

Tips

If data is being written or read asynchronously, the asynchronous operation is stopped.

instrreset is equivalent to issuing the stopasync (if needed), fclose, and delete functions for all instrument objects.

When you delete an instrument object, it becomes invalid. Because you cannot connect an invalid object to the instrument, you should remove it from the workspace with the clear command.

Version History

Introduced before R2006a

R2022a: To be removed

Not recommended starting in R2022a

This function will be removed in a future release.

This function is used by the serial, Bluetooth, tcpip, udp, visa, and gpib interfaces. These interfaces will also be removed in a future release, as previously announced. Use the following interfaces instead.

Functionality	Use This Instead	Additional Information
serial	serialport	Transition Your Code to serialport Interface
Bluetooth	bluetooth (case-sensitive)	Transition Your Code to bluetooth Interface
tcpip	tcpclient	Transition Your Code to tcpclient Interface
	tcpserver	Transition Your Code to tcpserver Interface
udp	udpport	Transition Your Code to udpport Interface
visa	visadev	Transition Your Code to visadev Interface
gpib	VISA-GPIB interface with visadev	Transition Your Code to VISA-GPIB Interface

The recommended interfaces have additional capabilities and improved performance. For more information about the recommended interfaces, see Interface-Based Instrument Communication.
