How to set the Ethernet/IP address of your new CompactLogix using the USB port


1769-L3, L2, L1If you're still using BOOT-P to set the IP address of your USB equipped 5370 CompactLogix, today I'll show you a much easier way.

First, you'll need a standard USB cable. This is the same type you would use with a USB printer with the familiar flat side which plugs into your PC, the nearly square side which plugs into your 5370 CompactLogix.

RSLinx USB Driver - RSWho finds L24Once you've connected you PC to your 5370 CompactLogix using USB, and have powered your CompactLogix on, you will see Windows load the drivers, and then a new USB driver appear in RSLinx automatically.

Note: To use the USB driver in RSLinx Classic you'll need to have a fairly recent version (no, the 1996 version will not work.) You can get the latest version of RSLinc Classic Lite for free from Rockwell HERE.

RSLinx USB Driver - Right Click on L24 to ConfigureWhen you expand the USB driver in the RSLinx – RSWho, you'll see your CompactLogix. At this point just right click on it, select Module Configuration, and the Port Configuration tab and you can now change the Ethernet port's IP address.

Tip: This procedure also works with the new 5570 1756-L7x processors, as well as USB 1756 Ethernet modules like the 1756-EN2T.
