Ethernet Devices/Considerations

Ethernet device requirements vary with specific applications. Regarding intended use, however, they fall
into two categories:
• Components of the Ethernet Open Connectivity Network, which links an HC900 Hybrid Controller to
Peers, to HMI Supervisory Stations, and to other Ethernet 10Base-T devices that support TCP/IP.
• Components of the I/O expansion network(C50 CPU only), which is an independent, private network
that is designed to work exclusively with the HC950 expansion racks.
Installation of the I/O expansion network is relatively straightforward; it includes only a few devices and
requires only configuration of jumpers in Scanner modules.
The Ethernet Open connectivity Network is potentially more complex than the I/O expansion network, and
in some cases, may require the services of an IT networking professional.
I/O Expansion Network(C50 CPU only)
Examples of HC900 Controller I/O expansion configurations are shown in Figure 12.
Crossover Cable
In Figure 12, any of the racks shown in each controller configuration can be 4-, 8-, or 12-slot versions.
Note that in configuration 2 (C50 CPU only), the Ethernet cable connects directly from the 10BaseT
connector on the Controller Module directly to the Scanner Module on the single I/O expansion rack. In
configuration 3 (C50 CPU only), the Ethernet cable goes from the 10BaseT port on the Controller Module
using a crossover cable to the Hub, and a straight through cable from each of the Hub ports to the 10BaseT
port on the Scanner Modules.
The Ethernet cabling for the I/O expansion links (C50 CPU only) are standard shielded Cat 5E cabling,
with standard RJ45 connectors. Each cable segment can be up to 100 meters (328 feet) long. Note that in
configuration 3, a second Hub is used in-line with the I/O expansion rack shown on the bottom of the
illustration, so as to extend the distance (up to an additional 100 meters) to the remote rack. The total
number of hubs allowed is limited to two in series between the controller and scanners. One combination
of two in series is illustrated.
