Updating your controller firmware via ControlFlash or AutoFlash 
software requires either a serial or other network connection to the 
controller.
Updating via an Ethernet connection is faster, but you must first 
install a 1768-ENBT Ethernet module to connect to the controller via 
the Ethernet network.
For information on installing, configuring, and operating a 
1768-ENBT module, refer to the EtherNet/IP Modules in Logix5000 
Control Systems User Manual, publication ENET-UM001
.
