Appendix C—Optional Communication Cards
Ethernet Card (C445XC-E)
Introduction
The C445 Ethernet option card (C445XC-E) supports both the
Modbus TCP and EtherNet/IP protocols. This card contains
two Ethernet ports but only one IP address. The ports act as
a two-port Ethernet switch, allowing the user to optionally
daisy chain modules together in a Ring or Linear network,
instead of running each module back to a centralized
Ethernet switch in a Star Network. Three supported Ethernet
network topologies for the C445XC-E card are shown below.

Installing the Ethernet Communication Card
The Ethernet Communication Card is installed directly into
the C445 Base Control Module. To install the card, follow the
step by step directions:
1.
Remove the blank cover with the unit not powered.
2.
Locate the communication card slot
3.
Plug the Ethernet communication card into location.
Only remove or plug in modules with the unit not
powered. Do not hot swap communication modules.
