Allen-Bradley 1794-AENT Flex I/O EtherNet/IP Adapter

The Allen-Bradley 1794-AENT is a FLEX I/O EtherNet/IP adapter module that bridges a FLEX I/O backplane to an EtherNet/IP network, enabling ControlLogix or CompactLogix controllers to read and write I/O data from FLEX I/O modules over Ethernet. It provides a single 10/100 Mbps Ethernet interface (RJ-45) for network connectivity and supports IP address assignment via BootP/DHCP using standard EtherNet/IP commissioning tools. As the single-port member of the FLEX I/O Ethernet adapter family, the 1794-AENT works in a FLEX I/O rack to connect distributed I/O to EtherNet/IP-enabled controllers, with Rockwell documentation noting its role alongside other FLEX adapters in enabling ControlLogix or CompactLogix systems. Typical applications include distributed sensor and actuator networks on the factory floor where high-speed data exchange between FLEX I/O and the main PLC is required, such as material handling, packaging lines, and process automation.
