Product Description

The Allen-Bradley 1785-ENET/C functions as a specialized Ethernet communication “sidecar” module, engineered to bridge the gap between legacy PLC-5 processors and modern Ethernet/IP industrial networks. By attaching this module to the host controller, users upgrade their existing automation hardware to support high-speed data exchange with supervisory systems (SCADA), Human-Machine Interfaces (HMI), and other networked controllers. This interface preserves the utility of established PLC-5 systems while enabling them to participate in contemporary plant-wide information architectures.

To initiate communication, the system recognizes the module through the processor’s Channel 3A. Because the 1785-ENET/C requires specific firmware and software recognition, operators must use compatible programming tools to designate this channel and assign a dedicated diagnostics file. This diagnostics file allows the system to monitor connection health and track communication performance in real-time. The module supports flexible IP addressing, permitting technicians to configure the unit manually through software or automatically via BOOTP server protocols.

Furthermore, the 1785-ENET/C delivers a robust electrical and mechanical connection to ControlNet 1.5 PLC-5 processors. It draws 2.2A of current at 5V DC directly from the controller assembly to ensure stable high-speed signaling without external power supplies. Its rugged USA-manufactured design withstands the typical electrical noise and environmental stressors found in factory floor settings. By incorporating this interface, facilities extend the operational lifecycle of their legacy assets while gaining the connectivity needed for data-driven manufacturing and remote system monitoring.
