Make Network Connections
You can make these connections to a CompactLogix 5370 L1 controller:
• Make a USB Connection
• Make EtherNet/IP Network Connections
Make a USB Connection
The controller has a USB port that uses a Type B receptacle. The port is USB 2.0-compatible and operates at 12 Mbps.
Use a USB cable to connect your computer to the USB port. With this connection, you can upgrade firmware and
download programs to the controller directly from your computer.
1. Plug one end of the USB cable into your CompactLogix 5370 L1 controller.
2. Plug the other end of the USB cable into
your computer.
This section describes the methods of connecting your computer to your CompactLogix 5370 L1 controller. This quick start was
written under the assumption that you have installed an EtherNet/IP network.
ATTENTION: The USB port is intended only for temporary local programming purposes and not intended for permanent
connection.
The USB cable is not to exceed 3.0 m (9.84 ft) and must not contain hubs.
WARNING: Do not use the USB port in hazardous locations.
