1785-ENET/C Functional Description

The Allen-Bradley 1785-ENET/C ENet/IP Expansion Module represents a sophisticated Ethernet communication interface module specifically engineered for integration with PLC-5 programmable controllers in industrial automation environments. This expansion module enables seamless network connectivity through standard Ethernet protocols, allowing PLC-5 processors to communicate effectively with factory networks and supervisory control systems. The technical implementation requires careful configuration of channel 3A within the controller architecture, which must be properly designated to support the communication functions of the module through appropriate programming software that recognizes this specific channel assignment.

Installation and configuration of the COMMUNICATION EXPANSION MODULE Allen Bradley 1785-ENET/C involves several critical steps including verification of compatible firmware revisions in the host processor and assignment of a dedicated diagnostics file to monitor communication status. The module supports multiple configuration methods including manual setup through programming software or automated address assignment via BOOTP server protocols available through Rockwell Automation's online tools. The operational requirements specify that the module must be physically attached to the PLC-5 processor for online configuration procedures, while offline configuration demands adherence to specific software documentation guidelines to ensure proper functionality.

Compatible with all ControlNet 1.5 PLC-5 processors, the Ethernet Interface Module AB 1785-ENET/C operates as a sidecar module that expands the communication capabilities of the base control system. The module's electrical specifications include a 5 VDC power supply with 2.2 amp current requirements, ensuring stable operation within the controller chassis environment. The Allen-Bradley 1785-ENET/C establishes Ethernet/IP connectivity that facilitates data exchange between the PLC-5 platform and various industrial devices while supporting network diagnostics through properly configured integer files that track communication status.

Through its robust design and comprehensive network capabilities, the 1785-ENET/C ROCKWELL Ethernet Interface Module provides a reliable bridge between legacy PLC-5 control systems and modern Ethernet-based industrial networks. The module's architecture maintains the ruggedness expected in industrial environments while delivering the connectivity necessary for contemporary automation applications. The continued utilization of the 1785-ENET/C Allen-Bradley PLC-5 SERIES across industrial facilities demonstrates its effectiveness in extending the operational lifespan of PLC-5 systems while enabling integration with newer technologies, thereby protecting investments in existing automation infrastructure.
