It connects a FLEX I\/O node to an EtherNet\/IP network, presenting up to eight I\/O modules installed in the same node to the controller as a remote I\/O device. The controller reads and writes I\/O data over the network as if those modules were in the local chassis. Each FLEX I\/O node requires one adapter — the 1794-AENT is the adapter for EtherNet\/IP-based systems.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1794-AENT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlatform\u003c\/td\u003e\n\u003ctd\u003eFLEX I\/O (1794)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Protocol\u003c\/td\u003e\n\u003ctd\u003eEtherNet\/IP (CIP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEthernet Speed\u003c\/td\u003e\n\u003ctd\u003e10\/100 Mbps, auto-negotiate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEthernet Ports\u003c\/td\u003e\n\u003ctd\u003e1 × RJ-45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax I\/O Modules per Node\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Messaging\u003c\/td\u003e\n\u003ctd\u003eClass 1 cyclic (I\/O) and Class 3 \/ UCMM (explicit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Address Assignment\u003c\/td\u003e\n\u003ctd\u003eBOOTP, DHCP, or static (via rotary switches or software)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Power Pass-Through\u003c\/td\u003e\n\u003ctd\u003eYes — V+ and V− rail to downstream terminal bases\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5V)\u003c\/td\u003e\n\u003ctd\u003e600 mA available to I\/O modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Power\u003c\/td\u003e\n\u003ctd\u003e24V DC (from field power rail)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0°C to 55°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEtherNet\/IP conformance tested, UL 508, CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFLEX I\/O Node Architecture\u003c\/h3\u003e\n\u003cp\u003eA FLEX I\/O node is a chain of terminal bases on a DIN rail. The adapter module clips into the first terminal base at the left end; up to eight I\/O modules clip into the remaining bases to the right. The adapter communicates with the controller over EtherNet\/IP and exchanges I\/O data with the attached modules over the FLEX I\/O backplane rail built into the terminal base chain.\u003c\/p\u003e\n\u003cp\u003eThe field power rail (24V DC) enters the node at the adapter's terminal base and passes through to all subsequent terminal bases — field power for all eight modules comes from the same entry point. If a new power segment is needed partway through the node, a 1794-TB3S terminal base with separate power rails or a power extender module can split the node into independently-powered segments.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: Does the 1794-AENT support Device Level Ring (DLR) topology?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eNo. The 1794-AENT has a single Ethernet port and does not support DLR. For DLR capability on FLEX I\/O, the 1794-AENTR (dual-port) adapter is required.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: How many 1794-AENT nodes can one controller manage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eThe limit is the controller's EtherNet\/IP connection count and backplane current budget — not a fixed node count. Each node consumes one EtherNet\/IP connection. Controllers with 256+ connections support dozens of FLEX I\/O nodes simultaneously.\u003c\/p\u003e\n\u003cp class=\"faq-q\"\u003e\u003cstrong\u003eQ: What happens to I\/O if the EtherNet\/IP connection is lost?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eThe adapter executes the configured connection loss action for each I\/O module — typically outputs de-energize (go to 0) and inputs hold last state until reconnection.

The eight module slots accommodate any combination of FLEX I\/O module types — digital, analog, specialty (thermocouple, RTD, counter) — in any order.
