Product Overview
PLX51‑DF1‑ENI is a high‑performance industrial routing module developed by ProSoft Technology. It bridges legacy DF1 serial‑based Allen‑Bradley controllers (SLC 500, MicroLogix, PLC‑5) with modern EtherNet/IP control platforms such as ControlLogix and CompactLogix. It supports bidirectional message routing, PLC program upload/download, tag‑based data mapping, and serial‑network diagnostic functions. Widely used for system retrofitting, legacy PLC modernization and replacement for discontinued 1761‑NET‑ENI module in automation sitesProSoft Te….
Series
PLX51 series consists of compact DIN‑rail mount protocol gateways for factory automation. Different variants realize conversion between EtherNet/IP and various serial protocols including DF1, Modbus, ASCII. These gateways focus on connecting legacy serial devices to modern EtherNet/IP control systems, supporting web configuration, built‑in diagnostics and redundant control system deployment for plant‑floor integration projectsProSoft Te….

Function
PLX51‑DF1‑ENI receives DF1 serial messages from legacy Allen‑Bradley PLCs, converts and routes them into EtherNet/IP CIP packets for modern controllers, and vice versa. It executes tag‑oriented data mapping, allows remote PLC program upload‑download over Ethernet. Embedded packet analyzer captures DF1 serial traffic for onsite debugging. DIP‑switch hardware controls support IP reset and configuration lock to avoid unintended parameter modification. It acts as protocol translator to realize seamless interoperation between old serial‑PLC hardware and new EtherNet/IP‑based automation systems.
Purpose
Realize interconnection between DF1 serial‑legacy PLC hardware and EtherNet/IP control systems. Serve as replacement for discontinued 1761‑NET‑ENI hardware. Support equipment upgrade without full replacement of existing field‑level controllers, reduce renovation cost and production downtime for manufacturing plants.
Application Fields
Automotive assembly lines, food & beverage processing, water‑wastewater treatment, material‑handling systems, oil‑gas auxiliary control systems, factory legacy Rockwell PLC modernization, industrial automation retrofit & migration projects.
