Product Details
Product Overview
The Allen Bradley 1756-ENET acts as a foundational Ethernet communication interface for the ControlLogix platform. This module enables high-level messaging and data exchange between controllers, computers, and other Ethernet-capable devices. Despite its discontinued status in the broader market, we provide this unit as 100% Brand New original stock. It provides a vital bridge for legacy systems requiring linear topology support and reliable 10 Mbps data transfer speeds without forcing a total system overhaul.

Engineering Advantages
-
Legacy Infrastructure Support: The 1756-ENET facilitates continued operation of Series A and B ControlLogix chassis. It allows engineers to maintain existing network architectures while ensuring the PLC communicates effectively with HMI and SCADA software.
-
Dual Connection Versatility: This module features both a standard Ethernet port and a 15-pin AUI port. This dual-interface design provides flexible physical layer connectivity options for older industrial transceiver hardware.
-
Instant Diagnostic Feedback: Three dedicated LEDs (TXD, RXD, OK) provide immediate visual status of network traffic and module health. This reduces troubleshooting time by allowing technicians to verify hardware functionality at a glance.
-
Chassis Flexibility: The module fits into any available slot in a ControlLogix chassis. This unrestricted placement simplifies panel layout and allows for optimized thermal management within the enclosure.
FAQs
-
Can I use the 1756-ENET for high-speed I/O control? While this module supports messaging and adapter functions, it operates at 10 Mbps. For high-speed distributed I/O, consider the 1756-ENBT or newer modules; however, the 1756-ENET remains the standard for maintaining legacy messaging links.
-
Is this module compatible with newer Series C chassis? The 1756-ENET specifically supports Series A and B chassis (e.g., 1756-A4 through 1756-A13). Always verify your backplane revision before installation to ensure full electrical compatibility.
-
How do I address the module on the network? The module utilizes BOOTP or DHCP for initial IP assignment. Use the Rockwell Automation BOOTP/DHCP utility to set a static IP address for permanent integration into your industrial subnet.
-
