Ethernet Network
The TCP/IP Ethernet network is a local-area network designed for the high-speed exchange of information
between computers and related devices. With its high bandwidth (10 Mbps to 100 Mbps),
an Ethernet network allows many computers, controllers, and other devices to communicate over vast distances. An Ethernet network
The 1747-BSN module contains the full complement of RIO scanner features, plus
backup capability for support of redundant processor applications. The backup system
consists of one or more pairs of complementary modules, with one module residing in the
primary system and the other in the backup system. The primary system controls the
operation of remote I/O, while the backup system monitors communications via the
high-speed serial link (HSSL) and is available to take control in the event of a fault in the primary system.
