216 Connecting to Networks via Ethernet Interface
MicroLogix 1100 and PC
Connections to the
Ethernet Network The MicroLogix 1100 Ethernet connector conforms to ISO/IEC 8802-3 STD
802.3 and utilizes 10/100Base-T media. Connections are made directly from
the MicroLogix 1100 to an Ethernet hub or switch. The network setup is
simple and cost effective. Typical network topology is pictured below.
Ethernet Network Topology
Connecting an Ethernet switch on the Ethernet Network
The MicroLogix 1100 Ethernet port supports the following Ethernet settings:
• 10 Mbps half duplex or full duplex
• 100 Mbps half duplex or full duplex
Mode selection can be automatic, based on the IEEE 802.3 auto negotiation
protocol. In most cases, using the auto negotiation function results in proper
operation between a switch port and MicroLogix 1100 Ethernet port.
With RSLogix500 programming software version 7.00.00 or later, you can
manually set the communication rate and duplex mode of an Ethernet port
you have connected to the switch port. The settings of the Ethernet port and
the switch port must match.
IMPORTANT
The MicroLogix 1100 controller contains a
10/100Base-T, RJ45 Ethernet connector which
connects to standard Ethernet hubs or switchs via
8-wire twisted-pair straight-through cable. To access
other Ethernet mediums, use 10/100Base-T media
converters or Ethernet hubs or switchs that can be
connected together via fiber, thin-wire, or thick-wire
coaxial cables, or any other physical media
commercially available with Ethernet hubs or switchs.
