8 Select FLEX I/O Communication Adapters
Select a Network
You can configure your system for information exchange between a range of field
devices and a specific scanner. You select the communication adapters for the
networks that meet your needs:
EtherNet/IP Network
EtherNet/IP is a network suitable for use in industrial environment and
time-critical applications. EtherNet/IP uses standard Ethernet and TCP/IP
technologies and an open application layer protocol called the Control and
Information Protocol (CIP). CIP is also the application layer used in DeviceNet
and ControlNet networks. The open Application Layer protocol makes
interoperability and interchangeability of industrial automation and control
devices on EtherNet/IP a reality for automation and control applications.
The 1794-AENT and 1794-AENTR connect FLEX I/O to Ethernet/IP
enabled controllers such as ControlLogix or CompactLogix.

and search for products under the FLEX I/O platform.
(2) Modules that have the letter K in the last position of the catalog number, before the series designation, refer to conformal coated versions of the standard modules. These
modules meet the following certifications: ANSI / ISA-S71.04-1985, Class G1, G2, and G3 environments; CEI IEC 6065A-4 Class 1 and 2 environments; UL 746E
(3) Modules that have the letter R in the catalog number, before the series designation, refer to redundancy versions of the standard modules and are meant for redundancy
networks.
(4) Modules that have the letters XT in the catalog number, before the series designation, refer to extended temperatures version of the standard modules.
