Connect a Computer to the 
ControlNet Network 
This chapter explains how to set up a computer to operate on a ControlNet 
network.

You need to load a ControlNet communication driver for a computer to 
communicate with other devices on a ControlNet network. A computer uses 
this driver to do the following: 
•  Upload and download controller projects over ControlNet using Logix 
Designer software. 
•  Schedule the ControlNet network via RSNetWorx for ControlNet 
software. 
•  Operate an HMI type application. 
Depending on the connection device, you can use one of these drivers: 
•  1784-PCIC or 1784-PCICS card—You must configure the driver in 
RSLinx Classic software, as described on page 26 on page 28
. 
•  USBCIP driver—Use only with a 1784-U2CN USB-to-ControlNet 
cable. You are not required to configure the driver in RSLinx Classic 
software. 
Important: 
If you are running RSLinx Classic software, version 2.51, 2.52, or 2.53, you must manually install the USBCIP 
driver. To obtain the driver installation package, refer to answer ID 55431 on the Rockwell Automation 
Knowledgebase at http://support.rockwellautomation.com/Knowledgebase. 
If you are running RSLinx Classic software, version 2.54 or later, the USBCIP driver is already installed on the 
computer. 
After preparing the driver for use, connect the card or cable to the computer, 
and then connect the computer to the network.
