Connecting to Networks via Ethernet Interface 217

Cables

Shielded and non-shielded twisted-pair 10/100Base-T cables with RJ45

connectors are supported. The maximum cable length between an MicroLogix

1100 Ethernet port and a 10/100Base-T port on an Ethernet hub or switch

(without repeaters or fiber) is 100 m (323 ft). However, in an industrial

application, cable length should be kept to a minimum.

Straight-through cabling

IMPORTANT

When connecting the MicroLogix 1100 Ethernet port

to a 10/100Base-T Ethernet switch, note the

following recommendations:

• Use the auto negotiation function for both the switch port and the

MicroLogix 1100 Ethernet port

• If you want to force to a specific speed/duplex mode, you should

force the MicroLogix 1100 Ethernet port and leave the switch in

auto negotiation mode to match speed/duplex settings of the

MicroLogix 1100. Ethernet port.

• If you want to disable the auto negotiation function for both

ports, then you should only force both the switch and the

MicroLogix 1100 port to either 100Mbps Half-duplex or 10

Mbps/Half-duplex.

If you attempt to force both the switch and the MicroLogix1100

port to either 100 Mbps Full-duplex or 10 Mbps Full-duplex, the

Ethernet link will not be established and Ethernet

communications will not work.

TIP

The Ethernet cabling with straight-through method is

recommended as below. Do not make the incorrect

connection.
