Networking Hardware

The iNetGrow system uses standard UDP/IP protocols over Ethernet to handle the data transfer between the controllers and the PCs. Each control unit (see Concepts) also runs a local network of modules, called the mNet, to handle the communications between the smart I/O modules and the controller. mNet also uses eight-conductor straight-through “Category 5” networking cables with RJ-45 plugs.

Connecting the various controllers to the LAN requires standard network hardware such as cabling and switches. A controller may be connected to the LAN using a wireless bridge. Use an “Access Point Client” and a “Wireless Access point.” For instance, the LinkSys WAP54G may be configured to run as a access point or as an access point client. So a pair of WAP54Gs could be used to construct a “virtual cable” connecting the controller to the LAN. The controller end of the virtual cable is the access point client and the LAN end of the virtual cable is the access point. Some wireless products contain a wireless access point along with other subsystems. A “wireless router,” for instance is a combination of a switch and a wireless access point (e.g. LinkSys WRT54G). So the wireless router can be used to connect LAN components through regular wired (the router side) or through wireless connections (through the wireless access point side).
