ControlLogix-XT ControlNet Interface Module 21
Publication 1756-IN634A-EN-P - April 2009
Configure RSLinx Software to Use the USB Port
The ControlNet interface module has a USB device port that uses a
Type B receptacle. The port is USB 1.1-compatible and runs at
12 Mbps. To use the USB port of the 1756-CN2RXT, you must have
RSLinx software, version 2.55 or later, installed on your workstation.
Use a USB cable to connect your workstation to the USB port. With
this connection, you can download programs to controllers and
configure other devices, which are accessible by the module, directly
from your workstation.
WARNING
The USB port is intended for temporary local programming purposes only and
not intended for permanent connection. If you connect or disconnect the USB
cable with power applied to this module or any device on the USB network,
an electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
A Samtec Inc. RSP-119350 USB cable is required to maintain hazardous
location certifications.
WARNING
The 1756-CN2RXT modules, series B, have an industrial Type B USB port. The
port has the same electrical characteristics as other Type B ports, but a higher
cable pull-out rating.
For typical applications in nonhazardous environments, you may use any
high-quality USB cable. If used in a hazardous location, a Samtec Inc.
RSP-119350 USB cable is required to meet the 15-Newton pull test for
hazardous environments.
ATTENTION
The USB cable is not to exceed 3.0 m (9.84 ft) and must not contain hubs.
