Allen-Bradley 1788HP-EN2PA Communication Modules
The 1788HP-EN2PA is an advanced communication linking device developed through the Rockwell Automation and Hiprom partnership to bridge EtherNet/IP control systems with Profibus PA field instruments. It functions as a direct master gateway, eliminating the need for an intermediate Profibus-DP layer. This enables seamless integration of process automation field devices directly into Allen-Bradley Logix platforms using standard RSLogix 5000 or Studio 5000 engineering environments.
Direct Integration Architecture
By acting as a true Profibus PA master on the network side, the 1788HP-EN2PA simplifies loop architectures in industrial processing plants. It connects directly to an Allen-Bradley Ethernet bridge or switch, mapping field instruments into the controller's I/O tree. This configuration allows process controllers to handle cyclic process variables and acyclic device diagnostics without complex third-party protocol converters.
On-Board Diagnostics & Display
Equipped with an integrated LCD panel, the module offers immediate, on-site visibility into system health and network traffic. Operators can monitor bus voltages, internal module temperatures, external power feed values, and individual field device node status directly from the hardware interface. This local diagnostic capability streamlines troubleshooting during commissioning and routine maintenance routines.
