Allen-Bradley 1785-ENET/C PLC-5 Ethernet/IP Interface Module

The Allen-Bradley 1785-ENET/C is an Ethernet/IP expansion module for PLC-5 series controllers. It enables high-speed networking via Channel 3A, supports BOOTP/DHCP addressing, and provides a robust bridge between legacy processors and modern Ethernet-based automation systems.

Product Description

The Allen-Bradley 1785-ENET/C functions as a high-performance communication “sidecar” module, specifically designed to bridge legacy PLC-5 programmable controllers with modern Ethernet/IP industrial networks. By attaching this module directly to a PLC-5 processor, users enable high-speed data exchange, peer-to-peer messaging, and remote programming capabilities over standard Ethernet architectures. This interface effectively transforms a standalone controller into a networked node capable of interacting with supervisory control systems (SCADA) and other Allen-Bradley processors.

To facilitate reliable data flow, the 1785-ENET/C utilizes Channel 3A within the controller’s internal architecture. Furthermore, the module supports versatile IP addressing methods, including manual static configuration via programming software or dynamic assignment through BOOTP/DHCP servers. Because the module draws power directly from the controller chassis, it maintains a small footprint while providing robust diagnostic capabilities. Engineers can monitor network health in real-time by assigning dedicated diagnostic integer files, which track packet integrity and connection status. Ultimately, the 1785-ENET/C protects existing hardware investments by allowing older PLC-5 systems to operate seamlessly within contemporary, data-driven manufacturing environments.
