Eaton E84BAN Communication Interface Module

The Eaton E84BAN is a communication interface module designed for use with Eaton XC200 and XC100 series programmable logic controllers. This module provides Profibus DP slave connectivity, enabling seamless integration of Eaton controllers into distributed automation networks. The E84BAN supports high-speed data exchange with Profibus DP masters, making it an essential component for systems requiring standardized fieldbus communication.

Technical Specifications

• Communication Protocol: Profibus DP (EN 50170, IEC 61158)

• Physical Interface: RS-485, 9-pin D-sub connector

• Baud Rates: 9.6 kbps to 12 Mbps, auto-detecting

• Profibus Address: Configurable via DIP switches or software

• Data Exchange: Up to 244 bytes input, 244 bytes output

• Power Supply: 5 V DC from controller backplane

• Current Consumption: 120 mA typical

Integration with Eaton XC Controllers

The E84BAN attaches directly to the side of XC200 and XC100 controllers, extending the communication capabilities without occupying additional DIN rail space. The module communicates with the controller via the internal expansion bus, providing a transparent interface between the controller application and the Profibus network. Data exchange is configured using the CoDeSys programming environment, where Profibus process data is mapped to controller variables. This architecture allows the controller to operate as a Profibus DP slave while executing control logic independently.

Profibus DP Slave Operation

As a Profibus DP slave, the E84BAN responds to cyclic data exchange requests from a Profibus DP master, typically a PLC or DCS. The module supports DP-V0 for cyclic data transfer and DP-V1 for acyclic parameter access and diagnostics. Configuration is accomplished using a GSD file that describes the module capabilities to the Profibus master engineering tool. The GSD file is provided with the module, enabling simple integration into any Profibus network.

Diagnostic Features

The E84BAN incorporates comprehensive diagnostic capabilities to simplify system troubleshooting:

• Status LEDs for power, bus activity, and diagnostic events

• Diagnostic data accessible via Profibus DP-V1 services

• Local error indication for rapid fault identification

• Watchdog monitoring for communication integrity

• Configuration validation at startup

Applications

The E84BAN is suitable for a variety of industrial automation applications:

• Integration of Eaton XC controllers into larger Profibus networks

• Distributed control systems requiring standardized fieldbus communication

• Machine automation with centralized Profibus DP master control

• Process automation systems incorporating Eaton controllers

• Retrofit projects upgrading legacy control systems

Environmental Specifications

• Operating Temperature: 0°C to 55°C (32°F to 131°F)

• Storage Temperature: -25°C to 70°C (-13°F to 158°F)

• Relative Humidity: 5% to 95% non-condensing

• Protection Rating: IP20

• Vibration Resistance: IEC 60068-2-6 compliant

Certifications

The E84BAN is certified by the Profibus International organization for interoperability with Profibus DP networks. It complies with CE requirements for industrial control equipment and meets UL standards for use in the United States and Canada. The module is manufactured under ISO 9001 quality management systems.

Installation and Configuration

Installation involves mounting the E84BAN onto the side of an XC200 or XC100 controller using the integrated locking mechanism. No additional mounting hardware is required. The module receives power from the controller via the expansion bus. Configuration is performed using Eaton CoDeSys software, where the Profibus slave interface is enabled and data mapping defined. The module address can be set using DIP switches or configured through software, providing flexibility for network planning.
