The Flex I/O Dual Port EtherNet/IP communication adapter module (1794-AENTR) includes two EtherNet/IP ports configured as embedded switches that support not only the conventional star and tree topologies but also the daisy chain and Device Level Ring (DLR) topologies. The DLR topology provides a level of communication redundancy that enhances product availability, says its maker, and the DLR also reduces and simplifies network wiring.
It can connect up to eight Flex I/O modules per adapter module. The extreme environment (1794-AENTRXT) communication adapter module operates in a broader temperature spectrum of -20 to 70°C.
Flex I/O was designed to be a cost-effective, flexible, modular I/O system for distributed applications that offers the functions of larger rack-based I/O without the space requirement. Users can independently select the I/O type, termination and network; and with more than 110 catalogue numbers and a breadth of specialty modules, Flex I/O offers support for hundreds of applications.
