Beckhoff EL6090 EtherCAT Display Terminal

Product Overview

The Beckhoff EL6090 is a specialized EtherCAT terminal that brings a Human-Machine Interface (HMI) directly to your DIN rail-mounted I/O station. Featuring a 2x16 character LC display and an integrated 5-position navigation switch, it allows operators to interact with the automation system, view diagnostic information, and modify local settings without requiring a separate, larger HMI panel. It also functions as a sophisticated data-logging module, featuring an internal, non-volatile operating hours counter and multiple secondary counters for maintenance and performance tracking.

Technical Configuration

The EL6090 is designed to bridge the gap between simple terminal blocks and complex HMI controllers.

• Interactive Display: The LC display supports scrolling text modes for messages longer than 16 characters and includes a switchable backlight for clear visibility in various lighting conditions.
• Navigation: The 5-position navigation switch (Up, Down, Left, Right, Enter) allows for intuitive menu-driven interaction, enabling the creation of custom parameter adjustment menus directly on the terminal.
• Integrated Data Tracking:
  • Operating Hours Counter: A 32-bit counter tracks machine runtime (overflows after 136 years) with secure data storage, ensuring that maintenance schedules are accurately monitored even after power cycles.
  • Time & Event Counters: Includes four additional 32-bit counters for specific process tracking (e.g., cycle counts, error counts, or time-in-state measurements).
• Robust Hardware: Like all EL-series terminals, it fits perfectly within the standard Beckhoff modular system, utilizing spring-actuated terminals for fast, vibration-resistant wiring.

Frequently Asked Questions

Is the operating hours counter truly permanent?

Yes, the terminal uses non-volatile memory that stores data even without power. Data is written to this storage automatically every 15 minutes or upon manual trigger, with a secure data retention lifespan of over 100 years.

Can I display dynamic process data (e.g., motor speed) on this screen?

Yes. Since the EL6090 is an EtherCAT slave, your PLC controller can write any string data to the terminal's process image. This allows you to display live system values, alarm messages, or status updates directly from your TwinCAT program.

How do I configure the menu structure?

The terminal itself does not have an "operating system." The logic for how to navigate menus and what text to display is programmed within your TwinCAT PLC code. You treat the terminal as a standard I/O device, mapping the navigation switch inputs to your own logic to control what the display shows.

Engineering Integration and Operational Best Practices

• UI/UX Design: Because the display is only 2x16 characters, keep your menu structure simple. Use clear, short abbreviations and intuitive navigation logic to prevent operator confusion.
• Write Frequency: While the internal memory is highly durable, avoid unnecessary constant writing to the non-volatile counter memory. Stick to the 15-minute automatic interval to maximize the lifespan of the memory registers.
• Cabinet Placement: Since this terminal features an integrated screen, ensure it is installed in a location on the DIN rail that is visible through a cabinet window or accessible via a maintenance door.
• Backlight Management: Use the switchable backlight feature to conserve energy and extend the life of the display. You can program the backlight to turn off automatically after a period of inactivity.
