Owning Palette: RT Utilities VIs

Requires: RT Module

Locks an RT target with a password to prevent unauthorized changes to the target configuration.

Details  

Use the pull-down menu to select an instance of this VI.

Select an instance RT Lock Target (IP)RT Lock Target (MAC)

RT Lock Target (IP)

	target address specifies the IP address or DNS name of the target.
	password specifies the password required to unlock the target.
	password-protect restarts? specifies whether to require the password to restart the target while the target is locked. Because the RT Restart Target VI does not include a password input, you must use the RT Unlock Target VI before using the RT Restart Target VI to restart a locked target programmatically.
	error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
	target address out returns the same address as target address.
	error out contains error information. This output provides standard error out functionality.

RT Lock Target (MAC)

	MAC address is the MAC address of the networked device. This input must be in hexadecimal format without : delimiters. Use the RT Get Target Information VI to obtain the MAC address of an RT target programmatically.
	password specifies the password required to unlock the target.
	password-protect restarts? specifies whether to require the password to restart the target while the target is locked. Because the RT Restart Target VI does not include a password input, you must use the RT Unlock Target VI before using the RT Restart Target VI to restart a locked target programmatically.
	error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
	MAC address out returns the MAC address of the target.
	error out contains error information. This output provides standard error out functionality.

RT Lock Target Details

Locking an RT target protects only network settings, system settings, software installation with the LabVIEW Real-Time Software Wizard, FTP access, and some VISA/PXI settings. In addition, a host computer cannot connect to the target in a LabVIEW project without a password unless the host computer is on the Target Access List on the User Access Properties page of the RT Target Properties dialog box.
