Components and Architecture - Ethernet Devices/Considerations
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
•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.

Examples of HC900 Controller I/O expansion configurations are shown in Figure 12.

In Figure 12, any of the racks shown in each controller configuration can be
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
