and Ethernet
Communication
Ethernet is a local area network that provides communication between various
devices @ 10…100 Mbps. The physical communication media options for the
MicroLogix 1400 are:
• built-in
• twisted-pair (10/100Base-T)
• with media converters or hubs
•fiber optic
•broadband
• thick-wire coaxial cable (10Base-5)
• thin-wire coaxial cable (10Base-2)
See the following page for more information on Ethernet physical media.
The MicroLogix 1400 supports Ethernet communication via the Ethernet
communication channel 1 shown in the drawing below.
