Appendix D EtherNet/IP Network Overview
A second network with Hosts D and E has been added. Gateway G2 connects
Network 2.1 with Network 2.2. Hosts D and E will use Gateway G2 to
communicate with hosts not on Network 2.2. Hosts B and C will use Gateway
G to communicate with hosts not on Network 2.1. When B is communicating
with D, G (the configured Gateway for B) will route the data from B to D...G2.
Manual Configuration on an
Ethernet Switch
The EtherNet/IP modules support these 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 autonegotiation
protocol.
Or
, with RSLogix 5000 programming software, version 12 and later,
you can manually set the communication rate and duplex mode of the
communication module and the switch port that is connected to the module.
If you manually set the communication rate and duplex mode, the settings of
the communication module and the switch port must match.
Change Ports on an
Ethernet Switch
If you reconnect the EtherNet/IP module from one port to another,
regardless of whether the new port is on the same or a different switch (or a
hub), perform this procedure.
1. Disconnect the cable from the port to which the EtherNet/IP module
is cur
rently connected.
2. Wait until the EtherNet/IP module Link Status status indicator is off.
3. Connect the cable to the new port.
T
his procedure restarts the autonegotiation process at the EtherNet/IP
module
side. Another option is to restart the EtherNet/IP module itself.
