LabVIEW RT Setup Menu
Use this menu to configure boot options for LabVIEW RT if it is installed on the controller. If
you are not using LabVIEW RT, you should leave these settings at default.
Note The settings below override the behavior of the switches shown in Figure 2-4.
Refer to the LabVIEW RT Configuration Switches section for more information. To
use the settings from the switches, select Use Switch Setting for each option.
• Boot Configuration—This setting selects whether the controller should boot
LabVIEW RT, LabVIEW RT Safe Mode, or an installed OS such as Windows 7. The
default is Use Switch Setting.
• Reset IP Address—If the controller is deployed to a different subnet from which it was
originally configured, or if the current IP address is invalid, use this switch to reset the IP
address and other TCP/IP settings to their factory defaults during LabVIEW RT startup.
The default is Use Switch Setting.
Note By default, the target automatically attempts to connect to the network using
DHCP. If the target is unable to initiate a DHCP connection, the target connects to the
network with a link-local IP address or 169.254.x.x.
• Disable Startup VI—If the controller becomes inaccessible because of a startup VI, this
switch can prevent VIs from automatically running at startup. The default is Use Switch
Setting.
