How do I configure the IP and other network settings of a new CompactRIO 9073 or 9074 controller?
Beginning in April 2009 for cRIO-9074 controllers and January 2010 for cRIO-9073 controllers, new controllers will feature automatic network connection. The cRIO-9074 will attempt to establish a DHCP network connection when connected to a network and powered up under the following conditions:
Previous revisions of the controller reset the IP address to 0.0.0.0 under the conditions listed above. You can identify the revision by the part number on the bottom of the controller. Older revisions have part numbers beginning with the following six digits: 192172. Revisions with automatic network connection have part numbers beginning with the following six digits: 198944. You can find this part number on the bottom label of the cRIO-9074 or cRIO-9073 Controller.
When you power on a new controller for the first time, it boots into safe mode because there is no software installed on it. The following describes how to configure the IP settings and install software on the controller.
Using IP RESET and SAFE MODE with Software Installed
The version of LabVIEW Real-Time installed on the controller determines how the controller behaves when powered up with the IP RESET switch on. With LabVIEW Real-Time 8.6.1 or later installed, the controller will behave as described above. With an older version of LabVIEW Real-Time installed, the IP address will be reset to 0.0.0.0. This behavior does not depend on the revision of your controller. Please keep in mind that when using LabVIEW Real-Time 8.6.1 and later, you must also use NI-RIO version 3.1 or later.
However, if you power up the controller with both IP RESET and SAFE MODE switches on, the controller will behave as if no software is installed, and the behavior is determined by the revision of the controller.
