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 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.

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

Figure 12 – HC900 Controller Configurations

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.
