The Ethernet ports on the module are Auto-Sensing. You can use either a

standard Ethernet straight-through cable or a crossover cable when connecting

the module to an Ethernet hub, a 10/100 Base-T Ethernet switch, or directly to a

PC. The module will detect the cable type and use the appropriate pins to send

and receive Ethernet signals.

Ethernet cabling is like U.S. telephone cables, except that it has eight

conductors. Some hubs have one input that can accept either a straight-through

or crossover cable, depending on a switch position. In this case, you must ensure

that the switch position and cable type agree.

Refer to Ethernet Cable Configuration (page 132) for a diagram of how to

configure Ethernet cable.

4.10.2 Ethernet Performance

High Ethernet traffic may impact GSC performance, consider one of these

options:

 Use managed switches to reduce traffic coming to module port

 Use CIPconnect for these applications and disconnect the module Ethernet

port from the network
