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. DLR also reduces and simplifies network wiring.

It can connect up to 8 FLEX I/O modules per adapter module. The extreme environment (1794-AENTRXT) version of the communication adapter module operates in a broader temperature spectrum, -20°C to 70°C, and provides a solution for extreme environment applications.

FLEX I/O is a cost-effective, flexible, modular I/O system for distributed applications and offers the functions of larger rack-based I/O without the space requirement. Users can independently select the I/O type, termination and network. With more than 110 catalogue numbers and a breadth of specialty modules, FLEX I/O offers support for hundreds of applications. Its features and reliability are why more than 10 million of the modules have been installed by machine builders and automation end-users worldwide.
