Description

The Allen-Bradley 1788-EN2PAR is a high-performance network gateway and linking device designed to facilitate seamless communication between EtherNet/IP control networks and PROFIBUS PA fieldbus segments. This intelligent bridge allows for the direct integration of process instrumentation, such as flow meters, pressure transmitters, and temperature sensors, into ControlLogix or CompactLogix systems. By eliminating the need for separate PROFIBUS DP master cards or intermediate segment couplers, this device simplifies plant architecture and reduces field-wiring complexity in process automation environments.

Features

  • Direct Network Bridging: Translates EtherNet/IP explicit and implicit messaging into deterministic PROFIBUS PA commands, enabling real-time diagnostic data and process variables to be mapped directly into the controller's tag database.
  • Integrated Power Management: Features a robust, pluggable Phoenix-style terminal block for external DC power input, supporting 24 to 18 AWG wire sizes for reliable power delivery.
  • Optimized Thermal Design: Engineered for vertical mounting configurations to maximize natural convection and manage a maximum power dissipation of 12.24 Watts.
  • Standardized Connectivity: Utilizes industry-standard Cat5 twisted-pair cabling for Ethernet uplinks, ensuring compatibility with common network infrastructure.

Applications

This linking device is engineered for demanding process manufacturing industries, including chemical processing, oil refining, wastewater treatment, and pharmaceutical batching. It is ideal for facilities looking to integrate bus-powered instrumentation into an existing Allen-Bradley control platform.

Installation Guidelines

  • Mounting: Must be mounted in a vertical orientation on a panel backpan to ensure proper thermal dissipation.
  • Environment: The unit is an open-style device and must be installed within a sealed, dust-tight, and moisture-controlled industrial enclosure.
  • Wiring: Ensure all power connections use 24 to 18 AWG solid or stranded copper wire. Secure the pluggable terminal block firmly to prevent intermittent contact.
  • Grounding: Follow standard industrial practices for grounding to minimize EMI/RFI interference.
  • Safety: Always disconnect power before installing or removing the module from the mounting surface.

FAQ

Q: Does this device require a separate PROFIBUS master card?
A: No, the 1788-EN2PAR acts as the bridge, allowing the EtherNet/IP controller to communicate directly with PROFIBUS PA instruments without additional master cards.

Q: What is the required mounting orientation?
A: This module must be mounted vertically to maintain its thermal rating and prevent overheating.
