HONEYWELL 51306673-100 EPNI

Description

Product Overview

The HONEYWELL 51306673-100 EPNI is a critical communication and network interface module for the Honeywell Experion Process Knowledge System (PKS). This specific module, identified as an Enhanced Performance Network Interface (EPNI), functions as the primary communication card for the C300 Process Controller, providing redundant, high-speed connectivity to the Experion control network (Experion Ethernet). The robust design of the HONEYWELL 51306673-100 ensures reliable data exchange between the controller, I/O modules, and the system’s servers and operator stations.

• Product Type: Enhanced Performance Network Interface (EPNI) Card

• Compatible System: Honeywell Experion PKS C-Series (C300 Controller)

• Part Number: 51306673-100

• Function: Provides dual, redundant 100Base-TX Ethernet ports for connection to the Experion FTEB (Fault Tolerant Ethernet Bus) or other plant networks.

• Redundancy: Supports true hot-swappable, 1:1 redundancy for maximum network availability.

• Protocols: Implements Honeywell’s proprietary, deterministic communication protocols for real-time control data, alongside standard TCP/IP for non-critical traffic.

• Controller Integration: Plugs directly into the C300 controller chassis, serving as its communication front-end.

• Diagnostics: Features comprehensive LED status indicators for power, network activity, fault, and redundancy status.

Advantages and Core Features

The primary advantage of the HONEYWELL 51306673-100 EPNI is its role in delivering deterministic, fault-tolerant network performance essential for process control. Its dual-port design and seamless redundancy switching ensure uninterrupted communication, which is critical for continuous process operations. The module is optimized for low latency and high data integrity within the Experion architecture. The 51306673-100 EPNI simplifies system integration and troubleshooting with its clear diagnostic indicators and is designed for high reliability in 24/7 industrial environments, forming a backbone of the Experion control network.

Application Scenarios

This interface module is deployed in any Experion PKS system utilizing C300 controllers across process industries:

• Oil Refining: Connecting controllers managing distillation columns, catalytic crackers, and hydrotreaters to the Experion servers.

• Chemical Processing: Enabling communication for batch reactors, continuous flow processes, and utilities control.

• Natural Gas Processing & LNG: Providing network connectivity for controllers in cryogenic plants, sweetening units, and compression stations.

• Pharmaceuticals: Facilitating data flow in batch-oriented production systems requiring high data integrity.

• Pulp & Paper: Linking distributed control for digester, bleaching, and paper machine control sections.

Comparison with Competing Products

Within the Experion ecosystem, the EPNI card is an enhanced successor to older NIM (Network Interface Module) cards, offering better performance. Competing products are the network interface cards for other DCS controllers, such as Emerson’s DeltaV controller cards or Siemens’ PCS 7 CP 443-1 communication processors. The HONEYWELL 51306673-100 EPNI is distinguished by its deep, firmware-level integration with the C300 controller and the Experion FTEB, providing a seamless, vendor-optimized solution for deterministic control traffic that generic industrial Ethernet cards cannot match.

Selection Guide and Important Notes

The HONEYWELL 51306673-100 EPNI is a required component for each C300 controller in an Experion PKS system. It is typically specified as part of the controller assembly.

Important Precautions:

• Controller Compatibility: This EPNI card is specifically for the C300 controller chassis. Verify the controller model and chassis type.

• Redundant Pairing: For fault-tolerant applications, two 51306673-100 cards must be installed in a controller as a redundant pair and properly configured in the Experion software.

• Network Design: The module must be connected to a switch or network infrastructure approved and configured for the Experion FTEB (using protocols like HSR/PRP or specific switch settings).

• Firmware Synchronization: The firmware on the EPNI card must be compatible with the version of the Experion software release and the C300 controller firmware.

• Handling: As a sensitive electronic component, proper ESD (electrostatic discharge) precautions must be taken during installation or replacement.
