In today's article I walk you through how to configure RSLinx to communicate to a CompactLogix processor using USB.
Step 1) Locate your CompactLogix's USB port
If you have one of Rockwell's 5370 CompactLogix processors, you find an orange USB port on the front of the unit as shown below:
NOTE: If you have an older CompactLogix and would like to connect to its serial port using a USB to serial converter, see our previous article HERE.
Step 2) Plug a standard A to B USB Cable into the CompactLogix
Step 3) Insure your have RSLinx Classic version 3.51 or later installed
Before you plug the other end of your USB cable into your computer, insure RSLinx Classic 3.51 or later is installed on your computer.
Step 4) Wait for Windows to install the Rockwell USBCIP driver.
Step 5) Open RSLinx Classic to find USB driver automatically added
Once Windows adds the USBCIP hardware driver, open RSLinx Classic and you should find the USB software driver has been added automatically:
NOTE: If you use RSLogix Emulate 5000, SoftLogix 5800, or another USB product from Rockwell, you may have to manually delete those drivers from RSLinx (including the “Virtual Backplane” driver,) and restart RSLinx before you'll see the USB driver appear in the RSWho window.
Step 6) Expand the USB Driver
Step 7) Your CompactLogix show now be displayed under the USB driver
After a few moments, you should see your CompactLogix processor appear under the USB driver in the RSWho window. At this point you can use this USB connection to your CompactLogix to flash firmware, change the Ethernet address, download a program, and go online:
